Plant

Daphne

12 US plant patents name this plant. 2 have expired, so those cultivars are free to propagate and sell. The next of the 10 still protected comes off patent on August 22, 2029.

Still under patent — 10 cultivars

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

Already in the public domain — 2 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 Daphne. 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.
