Here's a picture of some of the Andean root crops I've been growing. Species present are oca (Oxalis tuberosa), mashua (Tropaeolum tuberosum), ulluco (Ullucus tuberosus) and yacon (Smallanthus sonchifolius).
I'm a botanist and horticulturist with a longstanding interest in edible and useful plants. I founded an alternative seed company called Future Foods and I also worked in the Heritage Seed Library at Ryton Gardens, HDRA, growing heirloom vegetables for distribution to the members. I'm the only person I know who has tried to grow Japanese knotweed and failed.
Other interests include walking, cycling, music and natural history.
