Sempervivum 'Ohu Om Ohu' is a rare sempervivum cultivar from the Crassulaceae family, belonging to the hardy succulents native to mountainous regions of Europe and Asia Minor. These alpine succulents evolved to survive rocky, well-drained terrain with extreme temperature swings, making this cold hardy plant exceptionally tough and adaptable to harsh growing conditions.
Ohu Om Ohu forms tight, symmetrical rosettes with fleshy, pointed leaves in lime green and burgundy-red tones that deepen in cooler temperatures and bright sun. As a clustering succulent, it spreads by producing offsets around the mother rosette, creating a carpet-like mat over time. The compact rosettes have a jewel-like texture that sets this collector sempervivum variety apart in any collection.
Like all hens and chicks, individual rosettes bloom once and then die back, while the surrounding offsets carry on the colony. A noticeable drop in nighttime temperatures triggers the bloom cycle, so plants kept consistently warm may not flower as readily. The chicks left behind ensure it keeps growing long after any single rosette completes its life cycle.
This alpine succulent excels in rock gardens, alpine troughs, containers, and balcony planters, handling wind and light rain without trouble. You can leave it up to ten days without water. Ohu Om Ohu is cat friendly and dog friendly, so no concerns about curious pets investigating the rosettes.

Water it deeply but infrequently, allowing the soil to dry out completely between waterings, roughly every 10 to 14 days.
Ohu Om Ohu does best in gritty, fast-draining cactus soil blended with perlite or coarse sand at a 1:1 ratio.
It handles temperatures from -30°F up to around 90°F, showing exceptional frost tolerance across a wide temperature range.
