Full sun.

Frost tolerant

Yes, showy sedum is cold hardy once established, with the hardiest cultivars tolerating temperatures down to -30°F (-35°C).

Feeding

In early spring as new growth emerges, feed plants with a balanced organic fertilizer.

Spacing

Single Plants: 7" (20cm) each way (minimum)
Rows: 7" (20cm) with 7" (20cm) row gap (minimum)

Sow and Plant

Plant dormant roots or container-grown plants in spring. Sedums root very quickly and should show new growth within two weeks. Stems that break off during transplanting can be rooted in small containers of potting soil. Sedum is easily propagated by rooting stem cuttings taken from spring to early summer.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.

Notes

Showy sedum is a stalwart perennial that produces rosy flower umbels in summer that ripen to reddish brown in the fall. Use show sedum as a feature plant in perennial beds, where it will attract bees and other pollinators with their nectar-rich flowers. In spring, prune back the previous year’s stems to make room for vigorous new growth.

Harvesting

Gather stems of showy sedum for use in cut arrangements as you need them. Leave remaining flowers on the plants through winter.
