This has become one of my favorite spring bloomers, with electric sulphur color in April and May.

I asked in another thread, where the seeds would be, and got no reply, so here's the scoop.

After the flowers fade away, each of them leaves a little flat round disk on the flower stem. As they dry, these pods become translucent, and you can see the seeds inside. Strip them when they'll fall off into your hand.

Each pod has 1-4 small amber-colored seeds, which darken in color as they dry.
