Genus Phedimus and Sedum include around 600 species of nectar plants, of which 8 grow ferally in Finland. Many stonecrop plants are popular rockery and stone garden plants and no less than 45 species or varieties, many of which are very rare, grow in Finland. Several of the species that are cultivated in Finland are quite commonly found outside the garden too, as leftovers or escapes from cultivation. Escapes have received only a tiny fraction of the attention received by Finland’s native plants, but the first mention of wild Caucasian stonecrops was at the turn of the 19th and 20th centuries.
As its name suggests, the plant is native to the Caucuses, where it grows on shady and nutritious rock walls. It could be the most popular and common of all the stonecrops that are cultivated in Finland. Outside the garden it grows on rocky outcrops in southern Finland. Caucasian stonecrop’s flowers are naturally pink, but varieties might also have white or dark red flowers. Butterflies and bees are happy visitors, and the plant has a particularly good reputation for attracting butterflies. (Hylotelephium ewersii) is another red-flowered rockery plant that grows on thin soil that has been cultivated a long time in Finland and can sometimes be found as an escape. It is originally home to the mountains of central Asia, and in Finland it can be found growing slightly to the south of Caucasian stonecrop.
