What a generous idea to collect and post seeds all the way from Washington! My mum is a plantswoman extraordinaire and I know she has smuggled the occasional seed between countries. I am the more paranoid sort who phoned ahead to see if it was alright to bring my sour dough starter! I am putting the seeds in a seedbed in my potting shed to see what grows before committing to scattering them across our traditional medieval meadow. I will report back! Very excited and looking forward to seeing the seedlings pop up!
