Dear Diane Whitehead,
i only know of the tretraploid form of rizehensis which multiplies like a weed and has fused twin headed flowers or frequently two or more flowers to a scape and many other infirmities.All other forms of this species can be excruciatingly slow.My original clone from Potterton & Martin in the early eighties has made a small clump after all these years.One form that I collected in turkey recently flowers in November every year for the last two years.Quite a surprise.it was growing very low down near the black sea compared to all other populations.It seems to grow well but slowly,better than my original P. & M. form.
25 different galanthus in full flower on the 30th of jan.Since then it is spiralling out of count.
Kind regards,
Mark W. Brown
