Sedum kamtschaticum, commonly known as Kamchatka sedum or Kamchatka stonecrop, is a compact low-growing ground cover that typically forms a foliage mat to 6” tall spreading indefinitely by trailing stems to 12-18” wide. It is native to northern China and along the Pacific coast of Siberia including the Kamchatka Peninsula.
Thick, triangular, succulent, scalloped, spatulate to obovate, semi-evergreen, dark green leaves (3/4” to 1 1/2” long) are deciduous at the stem bases but tend to be evergreen at the tips. Tiny, star-shaped, yellow flowers (to 1/2”) bloom in flat cymes (each having 6-10 flowers) in June-August. Flowers give way to small fruits which turn russet red in fall. Most of the foliage disappears in cold winter months.
‘Weihenstephaner Gold’ is a cultivar that features starry pale yellow flowers which acquire pink tones with age, blooming in summer on plants clad with and silvery gray-green foliage. It typically grows to only 3-4” tall.
