Recently I bought a Ranunculus acris 'Suphureum' in a plant fair. I love it very much for its natural wild looks and wish I had bought a couple more.
So I was thinking of trying to get a couple of plants through seeds..
As I'm observing the process of the seed making in the seed heads, I noticed that seeds still green but seemingly fully developped brake loose by the slightest touch as if ready..
