Have googled and read about this beautiful bush (saw in a neighborhood
in full bloom and asked owner what it was).

Anybody have any negative words to say about it? I know enough to
gather those seed pods before they burst and self-sow.

Do you think it would do well in a large pot? I was just given a
volunteer from the person mentioned above (it's about 6" in a large
coffee can right now).

Thanks.
