Geranium Seed Collection: Zonal vs. Hardy Types

Zonal Geraniums (Pelargonium)

Many zonal geraniums don't produce seeds. Easier to overwinter: dig up, store upside down in cool (38–45°F), humid basement. Or take 4–6 inch cuttings, root in pots on sunny windowsills.

Hardy Geraniums (Cranesbill)

These produce seeds readily. Collect when pods are dry and split.

Seed Availability

Named zonal varieties that do set seed are sold by seed companies (Thompson & Morgan, etc.).
