Yes, nice color on that one. This species gives me nostalgic pangs from childhood every time I see one - which has been a long time now! Have you seen any alba flowers Mary? They seem to be more common in the northern reaches of the NE area compared to further south.
I haven't seen any alba in this colony, but I will check in the future. This patch seems to be doing fairly well by itself. But, per cnycharles' 2014 suggestion, we will pollinate a few flowers this year. ( When I say 'we' I mean my son-in-law ;-) )
