The Patent Garden

Genus

Verbena

466 US plant patents have been granted in this genus. 202 are already in the public domain — anyone may propagate and sell them. The next of the 264 still protected comes off patent on September 14, 2026.

On the name: Recorded as field [54] of the patent reads, verbatim. The previously stored value was a botanical/species name rather than a denomination.

Still under patent — 264 cultivars

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

Already in the public domain — 202 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.

A patent expiring frees the plant, and its cultivar name comes with it — cultivar names cannot be trademarked, so they are always free to use. What it does not free is any brand name the plant is marketed under. Those are trademarks and renew indefinitely.
