I've been scrutinizing my two snowdrop books in preparation for the season. In Snowdrops, by John Grimshaw and Aaron Davis, it was written that Dr. Ben Zonneveld of Leiden University was measuring the amount of DNA in snowdrop species and some cultivars, using Flow Cytometry. In 2003, Zonneveld, Grimshaw and Davis, published an article about this in Plant Systematics and Evolution. Tetraploids were found in Galanthus transcaucasicus and hexaploids in G. elwesii and G. lagodechianus. I grow a lot of elwesii. Does this mean that some of them are likely to be hexaploid? Would I look for the biggest ones? I have read that some of the best-known snowdrops, like Magnet, are triploid, which means they are sterile. Is there a list somewhere of tetraploid snowdrop cultivars? Diane Whitehead Victoria, British Columbia, Canada maritime zone 8, cool Mediterranean climate mild rainy winters, mild dry summers
