Wow, this one has a lot of different looks in the pictures in the database! It's beautiful in most of them. I don't grow this one, but Gossard has a lot of great intros; this one appears to share in that trend.

I can add a little here with my experience with 'Radiation Biohazard'. I received 4 fans from Miss Becky's back in 2017. It grew well, bloomed prolifically and multiplied very fast. Then I dug and divided it, after three years it still has not recovered. It is the only plant I remember having that showed such a poor reaction to being transplanted.
