I would call it like a mid/low rareness, i feel like alot of the ones considered rarer like 1-2 years ago got tissue cultured/ grown out enough to sell now which bumped down their trophy status

Albos, vurracossum, as well as some Anthuriums which would have been a lot harder to find back then ive seen in some Nurserys/garden centers unexpectedly

I check in with plant youtubers/insta for trends tho now my tastes are a bit more specific
