This is a beautifull plant. I have tried to grow this plant from seeds, but to no avail. I wonder if it is possible to grow this plant from seed? This plant blooms in early spring. Bees love this plant. I did notice, this year with lots of rain, that the plant rebloomed in September again. This plant multiplies itself slowly by roots.
