I sowed mine in a cold greenhouse in January this year on the advice of Carrie Thomas, National Collection holder. Excellent germination of all. Previously I'd sown them outside when ripe, this also worked very well but sometimes I had germination in autumn and had to look after tiny plants through the winter.
