Regrowing new peanese from it's own seeds?...

Hi. Could you post a picture of these as from your short description, they don't sound very ripe or mature.

When the carpels/seed pods of Paeonia are ripe and mature, they generally split along one side revealing a nice row of dark fat seeds (a bit like a pea pod).

Two other points to mention are that the genus Paeonia are very slow from seed. The other is generally, it is only worth growing the species (wild forms) from seed but this is still possible with the P. lactiflora and P. officinalis garden varieties if ripe seed pods are produced. The only thing with these is that the progeny will be different to the parent which could be interesting when they flower four-five years later.

I am concerned that you might have picked the pods too early and the seed is not yet ready. I always leave the pods on the plant until they actually split open.
