Respectable greenhouse product's identity stolen by medical marijuana

Green thumbs down

to a perfectly good horticultural term being usurped by the medical marijuana producers. "Pot crop" was once a major part of a greenhouse's sales, but now any mention of that category illicits giggles. Whatever will we call the plants grown in pots for sale as decorations now that checking an index reference to "pot crop" is likely to tell us all we never wanted to know about Cannabis production?
