I think that plant coming back to life is unlikely, BUT that may depend how low temps were...I had a frostbitten jade, and all afected branches fell off. It was left on a balcony for few cold nights (I don't know how many, & don't know how cold it was, but def. below 0*C). Maybe you remember, I posted the photos at least couple of times. Main stem/trunk was quite thick & didn't suffer. But every single branch - mostly tips or about 1-2", fell off. It may depend on how hard it is damaged; it reacts few different ways: Its leaves may wilt/collapse when they become warm again (I hink there is some tissue damage when it is frostbitten). Some leaves may turn brown or black and others may just dry out and shrivel. Some may fall off the plant and others remain attached. Parts of the plant may rot. Here are the pics of the said jade:

I trimmed some leaves before - they were blackish & mushy. Just about all the leaves you see in the photo fell off. And parts of the branches. I didn't think it will survive & didn't take photos after. It did over the years; photo below is same plant 3.5yrs later. The main trunk straightened up without me doing anything. There is orange line I drew showing what was left after frozen parts/branches fell off:

The plant is much bigger now - I don't have recent photos since I gave it away.

IF MY PLANT, I would cut off all damaed parts...

I'm going away for several days to help with my twin grandbabies. I think I'll cover it and re assess when I get back.

I'm pretty sure I'll cut back the grey stuff and hope the pink is still alive!

First it got frozen and now it will be covered? That sounds like a recipe for how to kill a plant. Can it be brought inside?

To ID plants, you can put pics of them in the "name that plant" forum:

Even in a less than perfect state, somebody might recognize. I've seen a lot of extra copies of many kinds of plants freeze to death.

No it can't be brought inside. This is only the second time in the 5 years we've been here that it has gone below freezing.

I figured I would cover it just in case we got more low temps, but got busy packing and forgot. No more freezes expected in the near future.

Don't understand the second part of your reply. First part....a bit ...never mind.

Are you commenting about my reply? I'm sorry if it wasn't clear. The second part is to say that somebody might recognize your plants, no matter what condition they are in now. Knowing what plant(s) you have would enable others to provide specific feedback about that plant. There are many succulents that don't mind freezing temps, some that can survive from the roots but the existing growth will turn to mush in a hard frost, and some that would just be killed. I hope your plants end up OK. :)

Tiffany, gotcha. I don't have this on my phone, so I'm not able to post pics. I might be able to do so on my tablet.

Well, it was a beautiful day and I went out and trimmed off the grey mushy stuff.

It looks like I have plenty of pink plant left!

It might take a year or 2 to get it to bounce back, but I wouldn't have any idea where to buy another one! We got this one at a nursery that was going out of business! I've only seen one other!

What a relief! Even if you don't want to add a pic to this discussion, you could take a pic to preserve in case something does happen to your plant. Should that happen, you would have the pic to ask people the name, and remember your pretty plant.

From your descriptions so far, I wonder if it is this?

No it isn't, but thanks for the site.

It's not that I don't want to post a picture, I would love to.

The problem is that I don't have this on my phone. That's how I take photos.

Hmmmm. Just realized I can take pics on my tablet and might be able to post pics from there!
