I can't remember but seems like I plant them up in 6 packs about late March. I left mine in 4 inch pots for most of the summer and planted out late September. They seem to really grow big once out of the pots. I will keep you posted. The last round of growing heuchera was some time ago. I'm excited for these. Last time I just took seeds off all my heuchera that were ready at the time of a one time gathering and mixed them up. So no idea of the pod parent. Also, I believe some of the heuchera hybrids maybe sterile, not sure on that.
