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.
Genus name comes from the Latin word sedeo meaning to sit in reference to the general growing habit of many of the sedums (they sit and sprawl over rocks).
Specific epithet is in reference to the Kamchatka Peninsula which juts out into the Pacific Ocean from the far eastern Coast of Siberia.
‘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. It is named after an agricultural college in southern Germany. Although this cultivar is listed herein as a variety of S. kamtchaticum, it is listed by some experts as a cultivar of S. kamtschaticum or as a cultivar of S. floriferum. Some experts consider var. floriferum to be a synonym of the straight species.
