Sedum Red Cauliflower

Royal Horticultural Society Award of Garden Merit

Sedum ‘Red Cauliflower’ is a unique, award-winning stonecrop known for its vibrant color and seasonal interest. Growing 8 to 12 inches tall, it blooms from late summer into fall with clusters of green buds that open into star-shaped flowers, transforming into one of the darkest reds found in garden plants. The vivid blooms pair beautifully with the succulent’s dark grey-green foliage, which may blush with cooler weather, creating a bold, eye-catching display. Although loved by pollinators, such as bees, butterflies, and hummingbirds, these flowers also make wonderful additions to fresh-cut arrangements.

Commonly called stonecrop, ‘Red Cauliflower’ (Sedum telephium) is a perennial that thrives in Zones 3-9. With a mounded, spreading growth habit, it’s ideal for use as ground cover, in rock gardens, or mass plantings. It’s equally striking as a container plant or mixed into borders. Its non-aggressive growth makes it a low-maintenance choice for gardeners seeking structure and color in their designs.

This hardy and drought-tolerant sedum flourishes in sunny locations with well-draining soil. It stores water in its fleshy leaves, making it an excellent option for arid areas or sandy soils. Heat tolerant and deer resistant, it’s a perfect addition to any garden requiring minimal care.

Plant ‘Red Cauliflower’ roots in spring, spacing them 18 to 24 inches apart and planting 1/2 inch deep for optimal growth.
