About Broadleaf Stonecrop

Sedum spathulifolium · also called Broadleaf Stonecrop, Spoon-Leaved Stonecrop · houseplant

Sedum spathulifolium is a low-growing native stonecrop from the Pacific Coast of North America, forming tight rosettes of spoon-shaped, waxy leaves dusted with a silvery or purple-flushed bloom. Hardy and adaptable, it suits alpine troughs, rock gardens, and bright indoor containers. Bright yellow star-shaped flowers appear in early summer. ASPCA lists Sedum as non-toxic.

Preferred mix: Lean, sharply draining gritty mix or alpine compost

Watch for — Crown rot in wet winters: The main risk outdoors in wet UK/Pacific Northwest winters. Rosettes blacken and collapse when sitting in waterlogged soil. Plant in raised beds or troughs with deep grit drainage layers, and ensure the crown stays dry. Move container-grown plants under cover in prolonged wet spells.

pH — does it matter for broadleaf stonecrop?

Broadleaf Stonecrop is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.

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 broadleaf stonecrop as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
