Derry Watkins is one of those quintessential British plantswomen that are endlessly impressive - I'd love to channel her brain, let alone plunder her garden! At least it's possible to get on her mailing list for seed unlike any you've seen before. Watkins sells fresh collected seeds of herbaceous perennials, tender perennials, annuals, biennials, grasses, umbels and almost every sort of plant apart from trees and aquatics. Many are her own new introductions.
Here's a tiny, tempting taste of what's on Derry's list this spring:
I can't quite imagine growing an agapanthus from seed, considering how much trouble I have getting them to bloom in my Langley garden...but this very dark blue Agapanthus Headbourne hybrids, or hardy lily of the Nile, might be worth the try...the grow nearly two feet high and bloom late summer (if your garden is warmer than mine).
