Don't you just love them? I harvest the seeds when they fall away easily from the plant. That usually happens once they become black. They look like baby elephant teeth don't they? They probably aren't as large here in Columbus, Ohio. It's a nice cottage garden plant.

Look at it this way: when the plant says they are loose and ready to go, they probably are.

Thank you for the advice... My plants are growing like crazy... I think if I let them... they could become trees! Do you know if they attract beneficial insects? Or hummers?
Thank you again!

I know my bumbles just love them and there are always bees and butterflies hanging around them. Enjoy your cool plant.
