Caucasian Stonecrop, Two-Row Stonecrop
Sedum spurium ‘John Creech’
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.
Sedum spurium ‘John Creech’ was named after Dr. Jon Creech, former director of the U.S. National Arboretum. Dr. Creech discovered this plant in the Siberian Academ Gorodok Gardens in 1971. The plant was identified by Ray Stephenson in 1971 as a rare, small-leaved, pink-flowered form of Sedum spurium.
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.
The genus, Sedum L., was named and described as such my Carl von Linnaeus in the first edition of Species Plantarum in 1753. Plants of the World Online by Kew currently lists 546 accepted species in the Sedum genus (as of when I am updating this page on March 24, 2019). They also list 44 genera that are now synonyms of the genus.
The genus, Phedimus Raf., was named and described by Constantine Samuel Rafinesque in the American Monthly Magazine and Critical Review in 1817.
Even though many Sedum species were reclassified in 1995, the change isn’t 100% official. The Missouri Botanical Gardens seems to be sticking with the Phedimus genus for some species, but Plants of the World Online by Kew are sticking with Sedum for the time being. Most other databases that changed the name to Phedimus have changed it back to Sedum…
In an email from the Senior Content Editor of Kew on August 23 (2018), he said: “As to Sedum, POWO still takes a wide view of the genus because there is not yet an agreed system to deal with it. Most of the research has been done in Europe on European species for which a number of genera have been made but it is unclear how they relate to the Asian and American species. So until this is settled we will retain a large Sedum.”
I bought this nice Sedum spurium ‘John Creech’ from Green Streets Market in 2017. This garden center always has a very nice selection of plants to choose from. This is where I also buy most of the seeds for our garden and where my dad did for many years before.
I planted this Sedum behind the old cast iron planter in the bed behind next to the foundation of my grandparents old home. The cast iron planter used to be a firebox in an old coal-fired furnace. A good friend of mine and I removed the furnace from a home in the early 1980’s and it has been in this spot ever since.
Origin: The Caucasus
Zones: USDA Zones 3a-9b (-40 to 25° F)
Size: 1/4-1/2” or so tall x 12-24” or so wide
Light: Sun to light shade
In my experience, Sedum does 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.
As with most “groundcover-type” Sedum, they prefer well-drained soil in full 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 this location, Sedum spurium ‘John Creech’ receives a good amount of sun all day until late afternoon as the sun passes over the foundation.
The upper leaves of Sedum spurium are evergreen while the lower leaves are deciduous. So, as cooler temperatures come, the lower leaves fall off…
During the winter the leaves turn a nice burgundy color. January 2018 was very cold, even down to -10° F twice the first week. The Sedum spurium ‘John Creech’ survived with flying colors…
As the temperatures started warming up and the day-length increased, its leaves started turning green once again.
After another month, it was looking very good!
Leaves along the stems are arranged in two rows, giving this plant one of its common names, Two-Row Stonecrop.
If allowed, it is no doubt Sedum spurium ‘John Creech’ would spread quite well…
I guess I need to put a few pieces in other areas, huh…
I was happy to see it had one stem with flowers but maybe it will have more in 2019. I tried several times to get better photos, but they were all blurry. I guess it is camera shy…
Even though we have had a very hot and dry summer, the Sedum spurium ‘John Creech’ has been a great performer. They like supplemental water during the hotter months, but sometimes I am busy or I have to water the plants whose life depends on it. Even though it has been sometimes over a week between waterings, all the Sedum in the bed behind the old foundation always does great.
The Sedum spurium ‘John Creech’ is a pretty good spreader and has been sneaking into the planter.
We have made it through the winter once again. It wasn’t near as cold as last winter and we had periods of nice days followed by several snows. As always, Sedum spurium loses its lower leaves and retains the top leaves. Soon warmer temps will stay around and the Sedum will start growing once again.
I will continue adding more photos and information as time goes by.
