Sedum 'Dazzleberry' is a compact hybrid stonecrop with dark burgundy-tinged succulent foliage and dense, flat-topped clusters of deep raspberry-pink flowers that emerge in late summer and persist through fall. It stays more upright and compact than older stonecrop cultivars, avoiding the tendency for large clumps to split and collapse at the center.
Plant in lean, sharply drained soil in full sun. Rich or consistently wet soil promotes lax stems and invites crown rot. Once established, the plant tolerates extended drought. In wet climates, a collar of coarse grit around the crown helps divert excess moisture. Leave top growth standing through winter to protect the crown; cut it back to the base in early spring as new shoots emerge.
Late-season clusters attract butterflies and bees when few other plants are in flower. Dried seed heads persist through winter, adding structural interest and providing forage for seed-eating birds.
Crown Rot
Lower leaves yellow and wilt; the base of the rosette turns brown and soft, sometimes with white fungal threads at the soil line. Plants collapse in wet conditions.
Remove and destroy affected plants. Improve drainage and avoid overhead watering. Do not mulch directly against the crown. Space plants for airflow and avoid replanting in the same wet spot.
Root rot
Plants wilt, yellow, and stunt even in moist soil; lower stems and roots turn brown, soft, and mushy and the plant may collapse. Most common in heavy, wet, or poorly drained ground.
Improve drainage and stop overwatering, and never plant too deep. Lift and destroy badly affected plants along with the soil around the roots. Grow in raised or free-draining beds to prevent it returning.
Fungal leaf spot
Brown or purplish spots on the leaves, often ringed with a yellow halo, that spread and merge in warm, humid, or wet weather; heavily spotted leaves yellow and drop early.
Pick off spotted leaves and clear fallen debris to remove overwintering spores. Improve air circulation by thinning, and water at the base so foliage dries quickly. If it persists, apply a copper- or sulfur-based fungicide at the first sign.
