Sedum sp. is a small evergreen sedum species. I received a small cutting several years ago and it did not have a species name with it, so I am not sure of the species of this one. In any case, plants grow to only 2-3 inches (5-7.5 cm) in height with attractive bluish green leaves that are 1/4 inch (7 mm) long that cover the plant. In the greenhouse, it is a fast grower and forms very dense clumps. Over two years, our plants have spread over 2 feet (60 cm), forming a wonderful groundcover in containers underneath our larger cacti and succulents.
Blooming: This species blooms in late spring to early summer. The very small flowers cover the plant. It is very showy whether in bloom or just as a groundcover.
Culture: Sedum sp. needs full sun to light shade or very high interior lighting with a well drained soil mix. In the greenhouse, we use a soil mix consisting of 1 part peat moss to 2 parts loam to 2 parts coarse sand. The plants are well watered and allowed to dry thoroughly before watering again. We fertilize them twice during the growing season, once in early spring and again in late summer with a balanced fertilizer. Since we use this plant as a groundcover with cacti and cold hardy succulents, the winter nighttime temperatures fall to 48°F (9°C). During this period we water very little--only enough to keep the leaves from shriveling.
Propagation: Sedum sp. is very easily propagated from cuttings or division of larger clumps.
Sedum sp. was featured as Plant of the Week February 23-March 1, 2007.
