This is an unusual primary hybrid that has bloomed for the first time. The plant is still small, but I am happy with the size and number of flowers. As far as I know this cross hasn't been registered yet. The tag actually says platyphylla x thomsonii, but platyphylla is "officially" ellisii -- at least for now. I don't see much thomsonii influence, but in the few other crosses I have with ellisii as a parent it does seem quite dominant.
