Serendipity strikes again!!!!!

The Crafters Choice envelope arrived Saturday. My first impulse was to put it directly into the recycling bag, since I had already replied to them via their website. But sometimes they offer an outstanding value on a book I MUST have, so I looked through the flyers and wouldn't you know it. On the front of the one with all the gardening books, there's a picture of the plant I've been trying to identify for all these years. Caltha palustris. Now I can research further to discover the other properties of this heretofore mystery plant. The book that was offered at cc was a book on animal resistant plants. And I just thought my plant was pretty.
