Caucasian Stonecrop, Two-Row Stonecrop
Sedum spurium ‘Tri-Color’
Sedum spurium M.Bieb. is the correct and accepted scientific name for this species of Sedum. It was first described as such by Friedrich August Marschall von Bieberstein in Flora Taurico-Caucasica in 1808.
Phedimus spurius (M.Bieb.) ‘t Hart is the accepted name on some databases. It was named and described by Henk ’t Hart in Evolution and Systematics of the Crassulaceae in 1995.
Sedum spurius was one of several Sedum species moved to the newly formed Phedimus genus in 1995. The change was accepted by some databases and not by others. Tropicos and the USDA Plants Database have opted, so far, to accept the Phedimus name. Plants of the World Online are sticking with Sedum spurium as the accepted name. I wonder what Tropicos and the USDA will say “after” and “when” they do an update…
Well, the change was made to reclassify species of the very large Sedum genus into smaller genera according to their similar characteristics. There are no “laws” that say what names have to be used and the curators of any database decide what names they choose. So, since this is my blog, I am sticking with Sedum spurium…
I bought my Sedum spurium ’Tri-Color’ from Lowe’s in Greenville, Mississippi while living at the mansion in Leland. They were very nice plants with green leaves with a white margin. I must have bought two because one is a pot and one is in the ground.
Origin: The Caucasus
Zones: USDA Zones 4a-9b (-30 to 25° F)*
Size: 6” tall or so
Light: Sun to light shade
*Some websites say down to USDA Zone 3a.
As with most “groundcover-type” Sedum, they prefer well-drained soil in sun to light shade. In areas with very hot summers, it is best to grow them where they have some shade during the heat of the day.
In my experience, Sedum do well in a slightly elevated bed or in pots where their soil can drain well. They do NOT like wet feet, especially during the winter months.
Information online says the leaves grow up to 2” long. Lower leaves are deciduous while new leaves are evergreen which typically turns burgundy during the cooler months. The leaves are arranged in two rows along the stems which is where they get one of their common names. Information also says this cultivar has a tendency to revert and produce a few all green leaves which should be removed. They produce star-shaped pinkish-red flowers in May through July.
