Plant

Geranium

987 US plant patents name this plant. 797 have expired, so those cultivars are free to propagate and sell. The next of the 190 still protected comes off patent on September 27, 2026.

Still under patent — 190 cultivars

Soonest to come off patent first. You may not propagate these for sale until the date shown.

Already in the public domain — 797 cultivars

Most recently freed first. Anyone may propagate and sell these plants — though the name it is sold under may still be a live trademark.

Botanically this is Geranium. A patent expiring frees the plant, and its cultivar name with it — cultivar names cannot be trademarked. Any brand name it is sold under is a separate thing and may still be owned.
