How did you find your way from Connecticut to the UK? I'd started a biodynamic vegetable garden in Connecticut and we used to have people come along at weekends to help out. A particular young man turned up: he returned many times and at the end of the summer I married him.
So it was all down to love? Isn't that the best way? I initially came over for just 2 years whilst Peter [Clegg] finished his studies at Cambridge. But then he came over here to set up his architectural studio in Bath with Richard Feilden. We eventually found this place and so over 20 years later, here I am.
There's quite a difference between vegetable growing and specialising in tender perennials though. Yes, my mother was a very keen plantswoman and I resisted following in her footsteps very strongly. Then when we first came to Bath, we built a wonderfully large conservatory onto our house because I was desperate for one. That's when my love of plants really took off. Tender plants are much more beautiful than hardy ones: their foliage is more interesting and they flower much more prolifically. My one regret about this place is not being able to have a large conservatory, but with way the site slopes here that's impossible.
How are your plants coping with the severe winter we've been having? I won't know until much later in the year [around May]. Of course, I've taken lots of insurance cuttings, which are overwintering in the greenhouse. But then it doesn't really matter if I lose something, I can try something else. I love trying new things.
Isn't there one plant you'd really regret losing? Well, there's my Melanoselinum decipiens. It's an monocarpic umbelifer which I've been nurturing for two years and it should finally get to look its best this year. If it's survived. [we had a quick peep under its protective fleece in the garden later and there were encouraging signs of green - fingers crossed it stays that way]
How do you look after all your plants and cuttings over the winter? The less tender plants are in the area at the top of the nursery under plastic (to keep the rain off), which gets pulled back most days to give them plenty of air. The tender ones are in the heated greenhouse which gets ventilated during the day. If it's below -2 degrees [centigrade] it's opened up slightly, above that temperature the doors are fully open. I believe in tough love: it means my plants are hardened up and ready to grow well come spring.
Is everything being kept on site here? No, Maureen [a former neighbour who has the use of a large greenhouse close to where she now lives and who popped in whilst I was there] also overwinters plants and grows on some of the seeds for me.
How do you prevent pests and diseases? Tidiness and good ventilation are the key to mould prevention [whenever we went outside Derry's fingers were constantly busy pulling off dead leaves and tidying up whilst we were talking]. I have to use chemicals to prevent vine weevil: as a nursery owner I cannot afford to sell a plant which is diseased or comes complete with pests or weeds. I use Neem oil (organic) in the greenhouse to prevent red spider mite and whitefly.
Are you using peat free compost? No it's around 20% peat. I haven't had good results with peat-free compost. A particular compost brand can be very variable and I need consistency to ensure good quality plants.
Do you grow all of your plants? It's around 80%, either from cuttings or saved seed. The other 20% are plants which I find difficult to propagate and I buy them in, or new seeds which I'd like to try. There's some wonderful Coreopsis 'Jive' young plants ordered for this year [as shown recently in the new Coreopsis featured in The Garden magazine].
Now is a quiet time gardening-wise, what do you do at this time of the year? I make sure the nursery is cleaned and tidied up, then there's the accounts and tax returns to do, website updates, putting together the catalogue, press releases, arranging group visits and just general organising. I love the natural rhythm of the year from this quiet organising time, then seed sowing and the garden clean-up starts next month and goes on into March, in April everything gets staked, in May there's the Chelsea chop, then the nursery gets really busy...
It's a while since your famous Black and White garden at Chelsea in 1999, do you have plans to do another exhibit there? Back then I used to do about 47 shows per year all over the country, and sometimes I'd do more than one over a weekend. I decided I wanted to get my life back, and I'd not previously exhibited at Chelsea, so it was a kind of fond farewell. At the time everything in the Floral Marquee was blowsy and colour, colour, colour. Mine was a complete contrast. The Head Gardener at Highgrove saw it and now there's something similar there. Lots of people found it inspirational because it was so different. I just do a few local shows nowadays, about one a month. However, whilst Chelsea was a goodbye to doing the big shows it was also the start of something. You can't sell plants at Chelsea, but you can sell seed. Chelsea was the start of the seed catalogue side of my business.
You also put together the programme of speakers for the University of Bath Gardening Club, how did your involvement come about? I just was just a member at first around 20 years ago when everything to do with the club was done by just one woman. It had very good speakers in those days too and was very popular. Then one year she stood up and said she wasn't going to do it anymore and the club would fold. There was a howl of protest and three of us volunteered to take things forward. That's the best way to get help with this kind of thing: threaten to give up and leave and a few people will volunteer.
Do you choose the speakers yourself or does the committee decide? I have a totally free rein and I get to choose the people I want to hear. It's great, they come on over and some of them stay here. It's the fun job to do on the committee. I'm thinking about asking the Head Gardener from the Inner Temple for next year's programme, what do you think? [Fantastic!!!!]
Where in the world inspires you? South Africa is my absolute favourite[and several of Derry's lectures are about South Africa]. You stop at the side of the road and you immediately see at least new 10 plants you don't know. I've just come back and I just love it there. We also do a lot of mountain walking: the Mountains of the Moon in Uganda were rewarding but extremely hard going, I've never seen such deep mud on the steepest of slopes! Peter and I will be going to Libya in the spring: I think there's a lot of North African flora that's relatively unknown and worth exploring.
At this point we went outside as I was keen to contrast my visit with last September's. I wanted to get more of an idea of the structure Derry's husband had put in place when designing and constructing the garden before she set to with planting up the borders. I just wish there was more of an opportunity to do this kind of thing at this time of the year: plants are lovely, but they do wave about and can get in the way of studying the structural elements of a garden!
I'll tell you more of what I found, plus a winter's look at the nursery soon. However, just before I go, Derry posed an interesting question during the close of our chat. We were mulling over how you get to meet the nicest of people when it comes to gardening. Her question was this:
Does gardening make us nice people, or is it only nice people that do gardening?
Now it's over to you...
