sedum ID

I was out at North Star Seed and Nursery in Faribault, Minnesota, USA.

They have two plants that came with the name "Sedum planifolium."

They are very different. One has half-inch red flat leaves; the other has very tiny blue-green leaves.

Any idea how to sort this out?

Does anyone have a picture of the real "Sedum panifolium"?

Re: sedum ID

Hi,

Impossible to guess the plants you described.
I suppose you have seen the description of Sedum planifolium, here ?

Re: sedum ID

Tom,

Yes, I found that description. It describes leaves that are narrower than the red-leaved plant. But it is rather difficult for me to follow these technical descriptions, especially when the ranges are so wide as in leaf length. I was hoping someone would have an image to compare.

I did take photographs of the two plants in question with a friend's camera, but have not yet figured out how to get the images from the SDHC card. If I can retrieve them, I will add them to this post.

Re: sedum ID

Yes, please, Henry, post the photos, I will show them Ray Stephenson, the expert on Sedum, he should be able to help you.

The Illustrated Handbook of Succulent Plants has the following remark :

"Fu & Fu (1984)considered S. planifolium to be close to S. japonicum [or uniflorum japonicum] but it differs by the longer, densely imbricate and flatter leaves, sepals without spur and free petals."

Maybe the comparison with japonicum helps ?

Re: sedum ID

I am familiar with Sedum japonicum 'Tokyo Sun'. Neither of these could be confused with that. Photos will come.

Re: sedum ID

So, I see Crassula pellucida 'Calico Kitten' and perhaps Hylotelephium pluricaule (we need flowers).

Re: sedum ID

Tom, Thanks! Neither of them fit the description of Sedum planifolium. Both of your suggestions fit well. The Hylotelephium has not flowered at the greenhouse, but it has been treated like a tropical. We will have to try it outdoors!

Re: sedum ID

Hylotelephium should be hardy .... where do you live, Henry ?

Re: sedum ID

I live in Minnesota. Zone 4. I just saw a tray of cuttings of the assumed Hylotelephium. They looked quite different from the image above,  Art at North Star said that was more normal. The stems were pinker and the leaves a little broader. I will try to get another picture. And some others that need ID now that I know about this resource.

Re: sedum ID

H. pluricaule is somewhat variable regarding leaf shape and size. Your plant will look more characteristic when grown outdoors.
