I AM CURRENTLY UPDATING THIS PAGE. IT SHOULD BE FINISHED BY 1-5-20 OR 1-6-20 DEPENDING ON WHERE YOU LIVE. THE NAME HAS CHANGED BACK TO PHEDIMUS AGAIN… I have more photos to add…

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 spurium M.Bieb. was first described as such by Friedrich August Marschall von Bieberstein in Flora Taurico-Caucasica in 1808.

Phedimus spurius/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.

The genus, Phedimus Raf., was named and described by Constantine Samuel Rafinesque in the American Monthly Magazine and Critical Review in 1817. According to Plants of the World Online, there are currently 14 accepted species in the Phedimus genus (as of 1-4-20 when I am updating this page). That number could change.

The genus, Sedum L., was named and described as such by Carl von Linnaeus in the first edition of Species Plantarum in 1753. Plants of the World Online currently list 456 accepted species when I am updating this page on 1-4-20. There were 550 accepted species when I last updated on June 8, 2019, when I am updating this page. Version 1.1 of The Plant List (not maintained since 2013) listed 392 accepted species plus 29 infraspecific names, a total of 655 synonyms, and 429 names yet to be assessed. The number of accepted species will continue to change. There are other databases but I think Plants of the World Online by Kew is the most up-to-date.

I had been in correspondence with one of the foremost Crassulaceae experts, Margrit Bischofberger of the International Crassulaceae Network, and she had this to say in an email in 2013…

“For the plant now called Phedimus kamtschaticus :

It has been described as a Sedum species in 1841 and has been considered a Sedum species for a very long time. The genus Sedum in a wide sense has been used to accommodate a great number of sometimes fairly diverse plants. At the end of the last century botanists have begun to separate certain groups with distinctive features and give them new names, > Phedimus, > Hylotelephium, < Rhodiola, > Orostachys etc.

So now the correct name of a group of plants with flat leaves which are often serrate or dentate is Phedimus.

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.”

It will be interesting to see how this plays out…

If you don’t mind, I am keeping both names in the captions… The next time I update, Phedimus may be a synonym again.

 

Phedimus spurius/Sedum spurium ‘John Creech’ on 5-31-17, #339-37.

I bought this nice Phedimus spurius/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 the garden and where my dad did for many years before.

I planted this Phedimus/Sedum (whatever you choose to call it) behind the old cast iron planter in the bed behind next to the foundation of my grandparent’s 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.

 In my experience, Phedimus/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” Phedimus or 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 Phedimus spurius/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 Phedimus spurius/Sedum spurium ‘John Creech’ survived with flying colors…

 

Phedimus spurius/Sedum spurium ‘John Creech’ on 3-9-18, #416-11.

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!

 

Phedimus spurius/Sedum spurium ‘John Creech’ on 4-13-18, #425-46.

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 Phedimus spurius/Sedum spurium ‘John Creech’ would spread quite well…

 

Phedimus spurius/Sedum spurium ‘John Creech on 6-14-18, #459-66.

I guess I need to put a few pieces in other areas, huh…

 

Phedimus spurius/Sedum spurium ‘John Creech buds on 6-14-18, #459-67.

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…

Looking AWESOME on June 28!

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, Phedimus spurius/Sedum spurium loses its lower leaves and retains the top leaves. Soon warmer temps will stay around and this clump will start growing once again.

Phedimus spurius/Sedum spurium ‘John Creech’ on 4-7-19, #558-34.

By April 7 the Phedimus spurius/Sedum spurium ‘John Ceech’ was greening up nicely and growing new leaves.

This colony is living up to its reputation as a spreading groundcover for sure…

 

Phedimus spurius/Sedum spurium ‘John Creech’ on 5-5-19, #566-70.

Trying to take over new territory in the cast iron planter…

What else can I say?

 

Phedimus spurius/Sedum spurium ‘John Creech’ on 6-14-19, #589-14.

It is always good to have plants that thrive in adverse conditions as well as when conditions are just right. This Pededimus spurius/Sedum spurium ‘John Creech’ performs well all summer long and has proved to be reliably cold hardy. I highly recommend this cultivar!

I will continue adding more photos and information as time goes by.

    thanks for your creeping sedum dairy 👍🏻. What sort of temperatures cause this sedum to loose its leaves? How would you compare it to Sedum makinoi Tornado?

    • Hello Wayne! As you can see in the photos, this Sedum loses most of its leaves when the temps get cooler. I have not grown Sedum makinoi ‘Tornado’. The only Sedum makinoi I have grows was ‘Salsa Verde’. I live in USDA zone 6a now and I don’t believe Sedum makinoi is cold hardy in this zone. So, I suppose hardiness is about the only comparison I can make. Sedum makinoi leaves are also MUCH smaller than Sedum spurium. I REALLY liked the Sedum makinoi ‘Salsa Verde’ when I lived in Mississippi. VERY NICE! Thanks for the comment!
