I have a spare f/s tuber of Corydalis maracandica, and fresh seed of it, C glaucescens, and C henrikii, flowerd as pairs of tubers open polinated.
I also have fresh seed of C shangii shangii, nudicaulis, and ruksanii flowerd as single tubers in proximity to each other and other species, and seed of ledbouriana grown next to a plant I believe is ledbouriana x popovii, I have collected seed from both.
I am looking to exchange for material of similar corydalis species looking for any seed to be likely pure species.
