Most paddles that you see are ones that have small holes within them. Solid paddles are ones that don’t have any holes. These paddles are a step up in resistance from the paddles with holes.

They look like small paddles or flapjacks, hence the plant’s common names. Native to South Africa, the paddle plant can be grown outdoors in USDA Plant Hardiness Zones 10-12 or as a houseplant.
