Bolara 60: A kitchen garden for this Croatian guesthouse

Bolara 60 is a beautiful house in a beautiful setting: it sits up in the hills above the Adriatic coast of Croatia, in Istria, the large peninsula which juts out into the Adriatic Sea just south of the Italian border. Originally a farmhouse, it has been carefully restored and renovated in traditional local stone and wood and is now a comfortable guesthouse. Sustainable living was an important factor in the restoration: solar panels on the roof heat the water in summer months, rainwater is diverted into an underground aquifer and pumped to taps around the ground for irrigation.

Bolara 60 is owned and run by Anna Colquhoun and Matt Purver as a guesthouse, an ideal base for anyone wanting to explore Istria and Croatia, and to experience the food and drink of the region. Anna is a cooking teacher, food writer, and academic researcher, who ran cookery classes and a supper club in north London as the Culinary Anthropologist for some years before coming out to Istria. Many of the guests come here to expand their food horizons and Anna will give classes and demos to guests on request.

As well as renovating the old farmhouse, Anna and Matt have planted fruit trees in the meadow below the house, and in the main garden, giving them figs, quinces, peaches, grapevines, kiwi fruit - a very popular shade-giving plant in Istria - and sour cherries. They have also restored the old kitchen garden, abandoned for over 30 years, with a new stone wall boundary and edged beds.

Anna invited me to come out to Bolara 60 to work on planning and planting the vegetable garden at the start of the 2018 season. Armed with my best secateurs, a suitcase full of seeds, and Anna's vegetable wishlist, I set off for Bolara 60 via Stansted and Ljubljana for a two-week working stay.

The vegetable garden is optimally situated on a south-facing slope. A line of bamboo (still standing among the ruins when Anna and Matt first set eyes on Bolara 60 in 2012) at the foot of the hill soaks up the water that runs down the slope, and provides canes to support beans and other climbing plants. Also here is the strawberry bed, and a separate perennial herbs bed with rosemary, thyme sage, lemon verbena, lemon balm, tarragon, and lovage. The banks are planted up with more rosemary, thyme and sage bushes and also lavender. Globe artichoke plants, apricot and plum trees line the side walls. That leaves six long rhombus-shaped beds for annual vegetables.

It's not often that you get a complete blank slate to work on with a vegetable garden. Matt rotovated all the beds, which were then left a few days before being hand-weeded. We - a team comprising Anna, myself and Bolara 60 volunteer Caitriona Courtney - cleared out the beds. Any perennial plant which was taking up valuable space was moved. Two globe artichoke plants were moved to nearer the side walls, where they sulked for a week before deciding to make a go of it and put on new growth. A couple of gooseberry bushes were taken out of the beds and transplanted to a shadier place between the kitchen garden and the house - ten days later, they were already showing tiny incipient fruit.

The garden needs to supply the kitchen and a continual houseful of guests, so there was much discussion about which crops to concentrate on. Anna and Matt don't at the moment want to grow potatoes or onions - plenty always available in the local farmers' markets. They do however want lots of tomatoes and various beans, from Borlottis to local varieties whose seeds are wrapped in unmarked paper bags. Tomatoes can be made into passata and used throughout the winter months, while the beans can easily be dried and likewise kept for months. So after some mapping and redrawing, we divided the beds into 1) tomatoes, 2) beans, 3) courgettes and cucumbers, 4) lettuces and salad leaves, 5) brassicas and beets, and 6) bitter leaves and roots.

Chillies and aubergines could be planted in the narrow beds set against the south-facing rear wall and benefit from the heat reflected off the stone, and Anna was also keen to grow squashes. Why not train them up the wall to scramble over the top instead of rambling haphazardly over the garden? There was space at the sides to dig out 60cm wide beds and grow the squash here. Melons could go along the side wall as well.

Sitting at the long dining table, which comfortably accommodates up to 16 guests in season, we pooled our seed resources. I'd brought with me a selection of Franchi seeds, with their provenance mainly in northern Italy, just over the border 45 minutes away, some old favourites such as my carefully hoarded Turkish rocket and tomatillos, and some that Anna had requested: purple sprouting broccoli, and good eating squash.

We stocked up on seed-sowing modules from a local agrarija (like Wickes, if only Wickes sold rows and rows of 250ltr vats for making wine, and olive oil presses) and spent a happy afternoon or two sowing 45 varieties of vegetable and constructing a mini-greenhouse from plastic sheeting and split canes. In fact we ended up calling on Caitriona's experience as a trained architect to advise on the design of the mini-greenhouse and her expertise paid off: the mini-greenhouse worked superbly.

I miscalculated the adjustment required between a Mediterranean climate (Istria) and a warm temperate one (London). While the squash seeds germinated after about a week and the brassicas in just a few days, as they do in the UK, the salad leaves, sown directly into the open ground, clearly enjoyed the warmth and the irrigation and germinated within 48 hours, Puzzlingly, the tomatoes wouldn't germinate at all. "How is this possible?" I asked. "Tomatoes always germinate." But I had failed to take into account that while the days were very warm, the nights were still cold, and the drop down to 10-12 degrees was too cool for the tomatoes. The tomato modules were brought indoors and seedlings started to appear in the next day or so.

Garden centres aren't as plentiful in Istria as in the UK, but the agrarijas sell seedlings in season and are well worth visiting in spring to pick up new stock as it comes in. We found chilli and aubergine plants, local tomato varieties, courgette and watermelon seedlings, which could go straight out into the garden and save a lot of space in the mini-greenhouse. The irrigation lines - essential in this Mediterranean climate where the year's rain falls mostly in winter and spring - were realigned to ensure that all the germinated seedlings and bought plants were getting their fair share.

By the end of the fortnight, we felt we'd made good progress. The brassicas were all in, the salad leaves growing apace, and the courgettes, chillies, aubergines and tomateos all well established and putting on good growth. Here's hoping for a bumper season at Bolara 60 this summer - Anna has reported that since I've been back in London, they have had their first batch of strawberries, their first artichoke and there are tiny courgettes already forming. 

I'm planning to return in October to help with the harvest and to get the garden ready for the winter months. For more details about Bolara 60 and planning a visit, see the website at, or for more on this stunning and unspoiled part of Croatia, look up Istria at

The outdoor grill: the large stone dining table is made from a single slab excavated during the renovation of the main house.
Kiwi fruit vine: the large leaves provide welcome shade in summer, and plenty of fruit in the autumn.

Shrubby herbs planted into the steep banks help to prevent soil erosion with their spreading roots and also attract bees and other beneficial insects int the kitchen garden.

Taming the Yacon monster

I have grown a monster. This is the harvest from just one plant, grown from a tiny seed tuber back in April 2017. Each one of those long oval roots is the size of a marrow. For all that it looks like a sweet potato it is in fact a yacon (Smallanthus sonchifolius), a tuberous perennial hailing originally from South America, historically grown on the eastern slopes of the Andes. It's also known as Peruvian ground apple and, in its native South America is also confusingly known as jicama. It's definitely not a jicama, though - jicama is a Mexican legume also grown for its underground rhizomes, although the taste is not dissimilar.

It is however related to the Jerusalem artichoke and therefore also kin to the sunflower. The relationship becomes apparent when the plant begins to grow in early summer with its sturdy, slightly hairy, stem and broad leaves. At the end of summer the yacon plant produces small bright yellow flowers very similar to those of the Jerusalem artichoke.

I first read about yacon in Mark Diacono's book A Taste of the Unexpected. At the time I was experimenting with growing oca, another South American tuber, and finding the results somewhat underwhelming. The idea of devoting yet more space to another 'lost crop of the Incas' did not really  appeal.

I was surprised by just how vigorous and tall the yacon plants grew, reaching around 2m by August. Even so, I had no idea what lay beneath until I harvested the first plant at the beginning of November. That yielded three fat sweet-potato-sized tubers, and I was pretty pleased with myself, so much so that I tweeted the following:

Little did I realise that I'd just pulled up the (very much) smaller of the two. The second plant I left to grow on, mindful of Mark Diacono's advice that the roots will stay happily in the ground until - and beyond - the first frosts.

There's no way I can use all this yacon at once. After adding them to salads where the mildly sweet, juicy crunch gives a winter salad some welcome texture, I also tried yacon remoulade, stirring julienned yacon into creme fraiche laced with mustard and a bit of lemon juice. They were julienned again with carrot for a dish based on a south-east Asian papaya salad: sprinkled with a dressing made with fish sauce, lime juice, crushed garlic and sugar, and topped with cashew nuts. That went down very well.

The roots store like potatoes: keep cool - say, around 5-10 degrees Celsius - in the dark, not too dry (they will wither), but definitely not damp (they will rot). Some roots won't keep, but those that do should stay good for weeks if not months.

There's also no need to to buy yacon starter plants each year. Once the giant swollen tubers have been removed, you're left with the stems and the small round buds around the crown. These will grow again the following season. Bury this remaining haulm and nodules in barely damp soil or sand and keep somewhere cool and dark - possibly the same place that is storing the roots for eating. Plant out again in spring, somewhere sunny and well mulched with manure, once the soil has warmed up a bit and the frosts should be over.  

You should probably protect the new leaves from slugs and snails, but I found the emerging plants needed little in way of cossetting. Last year was a notably good growing season for many 'long season' crops so it will be interesting to see how they do this year in whatever conditions 2018 throws up.

Autumn tomato chutney

Tomato blight ripped through the allotment in August this year, turning stems and leaves sooty-black and blotching the fruit. Every plant was dug up and burnt by August Bank Holiday leaving just the greenhouse plants, safe behind closed doors, to carry on free of infection.

My greenhouse isn't frost-free and we've had a few very cold mornings now, with the temperature dipping just freezing. While the chilli plants seem to be able to withstand temperatures hovering around zero, the tomatoes are grinding to a halt, the plants looking pretty exhausted, with brown papery leaves and wizened stems, just a few small fruit still slowly turning red in the sunny days.

I decided last week that it was time to put them out of their misery and to gather up all the remaining fruits, whether ripe or not, and make a big batch of late harvest chutney, so that none go to waste.

I've called this autumn tomato chutney because while it might lack some of the sweet sunshine and honeyed notes of tomatoes picked in high summer, the rag-tag of season's end tomatoes, green, pinkish, orange and red in places, has a concentrated, distinctively sharper flavour.

I added a few more autumn pickings: the last of the huge glut of tomatillos, which restore some of the zingy freshness of flavour, a warm chilli or two from the greenhouse for a little bit of fruity heat, and also one of my favourite chutney ingredients, dates. I use these instead of sultanas or raisins quite simply because I like them better, but also because they add a depth of sweet flavour, and a fudgy texture that definitely contributes to the finished chutney.

Apart from that, I kept the recipe as simple as possible - I don't think chutneys are meant to be complicated either in quantities or method. If you sterilise the jars and lids and utensils, this chutney will keep for a year or so - leave it for three months to mature before starting to eat it.

Autumn tomato chutney
500g tomatoes, mixed green and red
300g tomatillos
500g yellow onions
3 cloves garlic
Large thumb of fresh ginger
500g cooking apples
200g dried pitted dates (I used Deglet Nour from Waitrose but any will do)
300ml cider vinegar
175g soft brown sugar

Chop the tomatoes, onions, garlic and dates. Peel and grate the ginger. Remove the papery husk from the tomatillos and rinse any sticky residue off under the tap. Give a quick shake to throw off most of the moisture. Peel and core the apples, then chop roughly.

Put all the ingredients into a large non-reactive pan and mix with a spoon. You might want to hold back 25g or so of sugar and add it to taste as the chutney cooks, depending on how sweet your tooth is.

Bring to the boil over a medium-high heat, then cover the pan, reduce the heat and simmer for an hour and a half by which time the chutney should be dark and thickened.

While the chutney is simmering, sterilise jars for potting up. The amounts given here will fill around six or seven 250ml jars. I think the easiest way to sterilise them is to run them through the dishwasher on a hot cycle, then dry them off in the oven at 120 degrees while the chutney is bubbling away. You should also sterilise the lids and the utensils used for transferring the chutney.

When ready, spoon the chutney into the prepared jars, seal and leave to cool on a wire rack. Label, and transfer to a cool dark cupboard to mature before eating.

Mellow fruitfulness - autumn harvest

Along with the smells of mellow earth and burning leaves, autumn also brings aromas of vinegar, honey, sugar and fruits in our house. I only have a small freezer and no room to install a bigger one, so if I'm lucky enough to get a produce glut (and there's usually something that runs riot and produces far more than we can reasonably eat while it's still fresh), it needs to be preserved some other way.

Liqueurs, pickles, jellies and chutneys will use up a satisfyingly large amount of excess produce and keep for months - indeed, liqueurs and chutneys are often at their best if kept for months before you start to use them. You can happily experiment with ingredients and the balance of spicing to suit your palate and nearly always end up with something delicious - although I am still haunted by the spiced quince chutney which tasted fine but looked exactly like Pedigree Chum.


Jellies are I think particularly rewarding. They look beautiful: clear and in jewel-like colours. Quince jelly sets to a rich tawny amber colour; the golden lemon chilli jelly is almost irridescent when it catches the morning sun. They are versatile:can be spread on bread, rolls or toast, can accompany meats and cheese, a scant teaspoonful will lift a gravy and I did once, in extremis, use damson jelly as a filling for a Victoria sponge when I found the strawberry jam jar quite empty. They use up loads of fruit (and, it must be said, an industrial amount of sugar) and make good gifts for friends, school fairs and harvest festivals.

The quince jelly (above left) is made using the classic method: chop up quinces and boil in water with a little lemon juice for about an hour, then strain overnight through a jelly bag. The next day, boil up again using 450g sugar for every 600ml of juice, and boil rapidly until the setting point is reached.

The lemon chilli jelly (left) is made with an apple juice base: chop up apples, simmer in water with a little lemon juice* for an hour then strain through a jelly bag. Next day, boil up again using the same juice-to-sugar ratio as above - I find apple jelly very quick to set compared to others. While the liquid is boiling away, chop up around 60-80g of hot lemon** chillies and one yellow sweet pepper - I put them in the mini food processor to get the pieces very fine and it means I don't have to take my eye off the jelly pan for too long. Once the setting point is reached, turn off the heat and stir in the chillies. Stir the mix again when you're just about to pour into jars to ensure the chilli pieces are distributed evenly.

* This year's batch, very poncily, uses fresh bergamot juice as the citrus as I've had a big fat bergamot hanging from my Citrus bergamia bush all summer and hadn't yet found a use for it.

** I use yellow chillies to highlight the gorgeous honey blonde colour of this jelly, but finely chopped red chillies (and a red sweet pepper) would be visually stunning suspended in the pale jelly as well.


I'm not as adventurous with pickles as I could be: sweet peppers, and also chilli peppers, in glut years, will be preserved this way. I also regularly go through the shallots to pick out the smallest ones and pickle these in white wine vinegar, salt and tarragon. Peeling tiny shallots, even after they've been soaked in boiling water, is a pain, but once that's been done, it's a quick and easy method.

There is also always one pumpkin that you know won't be a keeper, whether it's been damaged, or as happened this year, because the fruit grew through the plastic mesh supporting the plants and ended up looking more like a Penny Bun than a pumpkin. Non-keeping squash will also be pickled: peeled, sliced into slim wedges and steeped in white wine vinegar, spiced with coriander, allspice, mace, ginger, chillies and a little star anise. This year I took inspiration from Karon Grieve's recipe at Larder Love and added a spoonful of sherry to the pickling liquor. Pickled pumpkin, served with pickled walnuts (sadly, not having a walnut tree, I have to buy these) and burrata or very fresh mozzarella, makes an excellent no-cook Christmas Day starter to keep everyone quiet while you finish off the main course.

Flavoured liqueurs are an rewarding way to use up a glut of fruit while creating something delicious. The basic method is to steep fruit, with sugar, in your chosen alcohol - I often use vodka because it doesn't have a strong flavour of its own but it's fun to experiment. Brandy and gin are both excellent vehicles for making a fruit-based liqueur and impart their own flavour to the finished drink.

You can leave the fruit and sugar gently infusing the alcohol for days, weeks, even months. The amount of sugar to add is really down to your own taste and also depends on the natural sweetness of the fruit. For the damson gin, shown here still at the infusion stage, I will add half the weight of the damsons in sugar, ie, 500g of sugar to every 1kg of damsons.

For blackberry vodka (creme de mure), below, you can use less sugar as the blackberries tend to be sweeter than damson and to use a similar amount would give you quite a cloying liqueur.

The infusion needs to be kept somewhere cool and dark and the process can't be hurried. At the beginning, you can up-end the jar every couple of days to get the sugar to dissolve; once it has, leave the mixture severely alone.

After a couple of months, you might want to taste the infusion - just to see how it's doing. It probably won't taste quite ready, so re-seal and leave alone again for another couple of months. But once it does taste a bit more rounded, a bit more full-bodies, strain the liqueur through muslin or a fine nylon sieve into a clean jar, reseal, put it back in the cool dark place, and leave again for a good couple of months before tasting.

I made the blackberry vodka at the end of July and I'm planning to use it in a celebratory Kir Royale to toast in the New Year. The damson gin above still has a way to go; I think we'll start sipping that with our first outdoor suppers next spring.

Note: when making any of these preserves, including the liqueurs for long-term storage and use, make sure all your jars, bottles, utensils, etc, are sterilised. This can be done easily enough in a hot dishwasher cycle, followed by drying them off in an oven at 120 degrees. Don't forget to do the lids as well!

Planting for a shady rockery

Choosing the planting for this rockery was one of my very first garden design jobs and I always appreciate the opportunity to return to gardens I have helped to create to see how they develop as the plants establish and settle. This planting is two years old now and the plants have matured and grown in an around the rocks. While it's always satisfying when the finished article looks much as you had envisaged it, sometimes plants grow together in unexpected ways and you can get a quite new, unintended but still appealing arrangement. 

 It was completely bare of any vegetation when I took it on, something I now know is quite unusual - a completely blank slate to work with.
Although laid out as a rockery, it faces east and is predominantly shady. Paradoxically the north end is the brighter side, as trees and fencing overshadow it on the southern edge. So the conventional sun-loving alpine plants had to be set aside in favour of leafier shade lovers.

When initially planted up, you can see the distances between plants quite clearly. The positioning of the rocks determined the spacing between plants just as much as allowing for their eventual spread. 

Two years on, and Buddha is sitting atop a wave of grasses, flanked by the two small conifers and the Japanese anemones as a backdrop. Tellima grandiflora provides background vegetation in spring and summer. The colour palette of mostly pinks and purples is designed to be visible from the kitchen window opposite at the far end of the garden.

At this time of year, the sedums form pink cloudy cushions for Buddha, and the Verbena bonariensis will add colour until the first frosts. their seed heads will add structure to the evergreen leaves over winter and then in spring the bed comes alive with bulbs: crocus, dwarf daffodils, chionodoxa, and snowdrops, and then tulips and yellow and gold primulas.

Plants that have done well in this somewhat unpromising environment include Heuchera - the 'Palace Purple' is crowding out 'Ginger Ale' and we will plant more 'Ginger Ale' next year to maintain the balance of light and dark leaves - Euphorbia myrsinites at the brighter end of the bed whose leaves look suitably alpine like, Luzula sylvestris, and the ferns. Tiarella puts on a brave display during the spring and early summer but is barely evident for the  rest of the time, and Alchemilla mollis is beginning to self-seed satisfactorily. My efforts to establish Aubretia have come to nothing so far: too dark and damp, I suspect and I am now looking for something else that will fulfil an Aubretia-like function, ie, tumble over the stones with some bright flowers, which is also better suited to the conditions.

The focal point within the bed was originally to be a single conifer, either a Juniper 'Skyrocket' or J. communis 'Hibernica', or ideally something slower growing. Buddha at the time was sitting rather lonely under a tree nearby and the client suggested moving him to the centre of the new rockery with his two conifer sentinels. He looked at home straightaway, and I swear his face has developed a smile since his move.

We had another serendipitous discovery while preparing the bed for planting. I cut back the ivy covering the fence behind quite dramatically and fund a few straggly and tattered wisteria stems underneath. By clearing a space around them and giving the wisteria more light it has shot up and this year gave us long racemes of blue flowers for a dramatic backdrop to the bed.

Sussex Prairie - a garden to immerse yourself in

Paul and Pauline McBride created a prairie garden in a field on the family farm in Henfield, Sussex. It is one of the most stunning examples of prairie planting I've ever visited. With large swathes of planting, waves perennials interespersed with drifts of grasses, the combination of colours, textures and shapes is incredibly beautiful.
The grasses are probably at their best now, in autumn. The plants will be left to form seedheads into the winter and provide food for birds, then early next year the whole lot is burned, ready for regeneration the next season.
Sussex Prairie Garden is set over 8 acres with wide curved beds, with bark chip paths running through the middle of each so that you can get right up close to the plants. This you will want to do - the grass fronds, cobwebby or soft like cat's fur, are immensely touchable.
Also contained within the garden is a teashop with excellent homemade cake (courgette, mango and lemon drizzle, sticky toffee...) and a shop selling many of the plants from the garden and also sourced elsewhere. Many of these are quite rare and not your run-of-the-mill garden centre cultivars, so well worth a look.

Sussex Prairie is open 6 days a week (closed Tuesdays) from 1.00pm-5.00pm until October 15th. It's an RHS partner garden so RHS members go in free, otherwise it's £7.00 for adults, £3.50 for children.

Dahlias - dramatic and dazzling in the autumn garden

As many summer blooms begin to fade with the advent of autumn, those flowers which will gamely carry on until the first frosts are especially welcome. Verbena, Rudbeckia and Geranium Rozanne are all earning their keep in the garden right now, but nothing can compete with the sheer showiness of dahlias, now in their pomp and bringing dazzling colour and dramatic shapes to the border. Whether singles, doubles, pompoms, or dinner plates, the flowers demand attention.

Personally, however much I admire the flower forms that look like old-fashioned bathing hats, or sea anemones, it is the simpler blooms that have enduring appeal. Nothing like some old-fashioned ecclesiastical dahlias to produce masses of flowers throughout the autumn.

Keen dahlia growers will disbud and prune side stems to encourage fewer but larger flowers; I'm content to deadhead - when I remember - and give the plants some discreet support as they grow tall. An open-topped paeony support, fixed before the dahlia begins to shoot up, is ideal, but I never remember, or never have spare supports, at the right time and usually end up with cane and string as usual.

My main concern is usually keeping the slugs off them when the plants are young. Slugs seem to especially like the growing buds and need to be picked off assiduously in a bad year. (Last year was terrible for slug damage, this year not so bad at all.)

After the first frost it's time to cut down the stems and then the big question is whether to leave the tubers in the ground, mulch on top with bark chips and cross one's fingers, or whether to lift the tubers and hang upside down somewhere dry, and cold but frost-free, for the winter. I've found I can usually get away with leaving them in my London town garden, but it's obviously better practice to lift them.

Come springtime when it's time to put the tubers back in the ground, you can also increase your stock by dividing up healthy ones. Find tubers with more than one 'eye' or incipient bud and cut cleanly so that each eye comes with a nice plump bit of tuber attached. Leave for a couple of days for the wound to heal before planting.
Star dahlias with their petals curling inwards look like children's seaside windmills and have a delicate prettiness in contrast to the exhibitionist tendencies of pompom and cactus dahlias.

Decorative blooms: lush overlapping petals and no central disc
