For several years, I have been trying to grow and flower specimens of N. minor ssp asturiensis. I have bought flowering plants labeled as N. asturiensis at shows and have grown some plants from seed. My "specification" is the description given in John Blanchard's book and uses the characteristics of waisted corona and green leaves. The plants I've grown from seed haven't flowered yet (flowers expected Spring 2016) but do have green leaves. All the flowering plants I have bought have somewhat glaucous leaves. Some of these plants have waisted coronas to the flowers but others don't have that pronounced waisting. The seed was ex JJA and JA.
So, are these glaucous leaved plants not actually asturiensis but N. minor or other sub-species of N. minor?
Wisley have a plant with glaucous leaves and waisted corona labelled as N. asturiensis.
Does the N. minor group naturally hybridise so it's difficult to find a "pure" John Blanchard specimen? Would DNA analysis enable one to separate the various forms of N. minor?
Any thoughts would be appreciated
