About Bluff Lettuce

Dudleya farinosa · also called Bluff Lettuce, Powdery Liveforever · houseplant

A compact California/Oregon coastal native succulent with tight rosettes covered in white, powdery farina. Extremely drought-tolerant and adapted to sea-bluff conditions — cool, dry summers with winter rain. Excellent for cool coastal gardens or a bright, airy indoor windowsill. Handle minimally to preserve the delicate chalky coating.

Preferred mix: Gritty, fast-draining cactus/pumice mix

Watch for — Etiolation: Stretched, pale growth indicates insufficient light. Move to a brighter location; the distorted form will not recover but new growth will be compact and tighter.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

A decent bagged houseplant compost works for bluff lettuce as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.

Drainage and the pot
