Sedum clavatum

Not all sedums are cold-hardy mountain plants, and Sedum clavatum makes that clear from the start. It's a Mexican species — from the highlands of Tamaulipas, to be specific — with chunky, club-shaped blue-green rosettes that have a sculptural, almost architectural quality. The leaves are thick and fleshy, tipped in a slight point, and arranged in perfect rosettes that stack and cluster over time. In bloom it produces white flowers that hover above the rosettes on upright stems. It's Zone 8 to 10, which makes it tender in most inland PNW locations.

On the mild west side of the Cascades — particularly in the maritime-influenced areas of coastal Oregon and Washington — it can overwinter in a protected spot or a south-facing rock garden with excellent drainage. More practically, it shines as a container plant: a terracotta pot on a sunny porch, a mixed succulent arrangement, or a summer patio display that comes indoors before the first hard frost. The blue-green rosettes pair beautifully with warmer-toned succulents and sedums in mixed containers. For the right conditions or the right container situation, Sedum clavatum is a rewarding and genuinely beautiful plant — just know its limits and plan accordingly, and it'll be one of your favorites.
