A new view of Asclepias curtissi

Asclepias curtissi appears to be more common this year on my island. I've seen several plants and they are usually white when in full bloom and begin to yellow in decine. Over the weekend I found a few with a lilac tint. They appear to be new flowers--one had a few unopened buds. I will post photos when I get them back. It is thrilling to find little secrets about plants you think you already know.
