Genus

Tetrazygia

1 US plant patent has been granted in this genus. 1 is already in the public domain — anyone may propagate and sell it.

On the name: Filed as Tetrazygia. Now generally treated as a synonym of Miconia.

Already in the public domain — 1 cultivar

Most recently freed first. Anyone may propagate and sell this plant — 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.
