Hi. I posted this thread: The thread "Mysteries in container!" in Sedum forum about a mixed container I was given, and one item identified is Sedum makinoi 'Ogon'.

I put most of that into a container and sunk it in the ground outside because I want it out there and I'm not ready to site it til next year when new beds are ready.

The recent cold temperatures do seem to have damaged it; the leaves looked affected, when I checked it yesterday. Today, it is warm and rainy but tonight and tomorrow is forecast to freeze again. Sad I do have a few sprigs of the Ogon inside here, but hope to protect the main part of it outside. I put a little light mulch over the top of it yesterday but no idea if that will help or not.

So, should I just bring it all inside? I kind of want to see if it will survive this, but I also would hate to lose so much of it.

The other sedums that are outside are all fine.

'Ogon' outside in the winter has not survived for me even in a relatively protected site with some mulch cover. Temps dropping into the upper 20sF have damaged the growth, though those didn't kill it outright. I'm in zone 7b. There is continual heat/cool temps fluctuating in the winter months and never any snow cover. Those may be a factor in the lack of survival here. We usually have at least one cold snap that gets into the lower teens and occasionally into single digits. Whatever the reasons, when spring returns 'Ogon' has not been there to see it. I bring mine into the garage or on the closed in porch, though I often have it outside when temps are staying above 32F.

Donald, thanks. Eh, I guess I will lift that pot and bring it in. We're definitely going into the 20s, and did once, which is when it took damage. It isn't completely dead yet (leaves at the base looked okay) but clearly not doing wonderfully like the other three I have out there.

I think our database ought to be modified to reflect this. I'd call this a zone 8 hardy plant, but not a zone 7.

Too bad! It's so lovely when it spreads among rocks....

Here's the freeze damage. Looks like there might be some healthy bits down in there, and as I said I do have a few sprigs inside in other pots:

But our member @Catmint20906 says she has this outside in her zone 7 garden, so I am not sure what's going on. I wonder now if I have a different plant.

Here's a healthy bit, but the flash compromises the color:

In the colder zones of 7 'Ogon' will go dormant/semi dormant.
My son's neighbor in Annandale, VA has had it growing outside for a number of years. It comes back every spring, and has made a most beautiful large colony underneath a Japanese Maple.
I took this photo the end of November while I was visiting. The colony covered the entire space under the maple.


It's a good idea to cover your base though.

Huh. Well, I think I won't plant any outside until spring. And hope the one whose top frizz manages to recover.

Er, unless you think wintering it inside is a bad idea?

I *do*, now I recall, have a teeny patch still outside, because it was attached to a semp I put in the ground so I left it there. It may become a test patch, LOL!

If you can I would do it in several different ways, to see which is more successful. I do know that the photo of the one in my above post was it a somewhat protected position by the front of the house. In the summer it had filtered light under the tree. Protection in both summer and winter.

I've wondered about it, too, Kyla. The burned foliage in your photo should recover, I think. At least mine did that I protected subsequent to being frost bitten. I seem to always have a bunch of this growing in various ways because the tiny pieces root and form new plants and colonies easily. Mine has been in containers of various types along with other plants and directly in the ground. Those directly in the ground and in some containers have been left out in winter and just have not survived. However, it takes a while for the plant to be completely knocked out. It obviously has some resistance to cold, just not enough where I've tried it. I have a nice patch this year right next to the garage and so far it looks okay. Some with more exposure looks the same as yours. I'm thinking I may turn an empty pot or two over it and see if that will be enough for it to survive outside.

Okay. Well, I am well set up to try several things. The main plant, though, which has the freeze damage and which I brought inside, I think I am going to wait for a milder stretch (HA! assuming there will be one! but I hear that is a usual pattern) and if it has recovered sufficiently I'll try putting a larger patch outside, somewhere. It will be fun to experiment a little.

I had Ogon outside last year, zone 7a, did not survive our 0 degree nights. Zero degrees is not the norm here. Bought new one this year and have brought a clump inside for the winter.
