I did promise to give you illustrations of these plants I've been writing about, here is the first one. This is Beggar's Purse. I forgot to note anything about seeds when I sketched this up. I apologize for the lack of color, I can't find where my stock pile of colored pencils went. And I didn't feel comfortable using my boys' crayons for this.
As you may see, the blossom has a shape similar to a pouch. The leaves are similar to broad leaf platain and it grows fairly low to the ground. And the roots are fibrous.
