These look great. I just transplanted one a little larger than these and it went into shock but i think it will recover. I know your zone pushing these in Gresham so my question is...whats your stratagy for getting them through the winter. I would plant one in the ground as a test through the winter. I think it would survive in a well draining location unless you had a very cold snap, like under 20°, for an extended time. I have'nt seen any siblings of yours here yet, but the rains have just started and I expect I'll be weeding them out by spring if they germination rate like yours. Here is me and the parent plant of yours. I'm 5'10". I'm hoping to have two in bloom in 2016 and more very year after. They are quite eyecatching.
