I haven't visited since "allplants" became "garden.org."Can someone tell me how to get to
the DETAILED descriptions of lilies, put together by the Brits. In a few months I'd like to do some crossing, and knowing the ploidy of each lily might help. 3Pete

The thread "Lily register links" in Lilies forum

Not all entries note the ploidy so if you don't find what you are looking for then ask in a thread on the forum, someone might know.

@3pete - I have been compiling a list of ploidies, so this may help you:
