Is it typical that there be NO seed pods on the plant?
Most of my pods have already cracked and split. I cut branches in mid november for seed pods that looked nearly ripe to save. I only had a few on either of my two plants. One, an immature bush that came up this year, had none. It only bloomed once.
Is it typical? No. If it bloomed and if it got any pollination there should be seed pods.
Plants have to be sexually mature to reproduce; improved varieties are cloned via cuttings. Butterfly Bush seeds need stratification (cold treatment) before they germinate, usually 3-4 weeks in the fridge will do.
