Celandine Poppy

I had a picture of Celandine Poppies (Stylophorum diphyllum) at Garden in the Woods a few days ago, but this closeup is from my own garden. I love their bright yellow flowers and the way they self-seed and pop up all over in the shade without becoming agressive about it. The bloom time is fairly long, extending through May and into June, and the foliage is bright green and quite attractive also. I think the seed pods look nice, but if you want to slow down their spread, you could pick the pods off before they scatter their seed..

I think they look particularly nice when paired up with something blue. Here it's Pulmonaria angustifolia.
