PILF
The list

Light 1. Rooms with no window.

A hallway, a bathroom, an interior desk, the corner the lamp doesn’t reach. Almost nothing wants to live here. These will.

Grade ALight 1
The best plant for a dark room, full stop. Water monthly.
Grade ALight 1
A close second. Slightly cheaper, slightly slower.
Grade ALight 2
Copes with a dim room — it’ll grow slowly and stay small. Not the marble queen; that one needs a window.
Grade ALight 2
Same as pothos. Fine in the dim, just slower.
Cast Iron PlantNot on a PILF shelf
Grade ALight 1
Victorian parlours had gaslight and coal smoke. It survived those.
Parlor PalmNot on a PILF shelf
Grade BLight 2
A small palm that’s fine across the room from a window. Water weekly.

Grades and light numbers follow the PILF Scale. “Not on a PILF shelf” means any plant shop has it — buy it there, and use the scale to know what you’re getting into.
