Plant

Stromanthe

2 US plant patents name this plant. 1 has expired, so that cultivar is free to propagate and sell. The next of the 1 still protected comes off patent on June 2, 2033.

Still under patent — 1 cultivar

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

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.

Botanically this is Stromanthe. 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.
