cold damaged plants

Hey everyone. I hope folks managed to get through the big freeze with no major damage to your homes or selves. Our plants, however, may be another story. Curious to hear if people are losing some tender or borderline hardy perennials or shrubs after having -10 degrees in central OK.

I was terribly worried about my figs, society garlic, lantanas, prickly pears, Japanese Aucuba, and Carolina Jessamine. A lot of that I managed to cover up (even the Aucuba), and so when it got another foot snow dumped over them, I think they were insulated enough to survive. My Jessamine vine, however, is in very bad shape, as it was too large to be protected from the cold. I was wondering if anyone had any idea about trying to save it. Do you think that if I cut it off at the ground it will come back? It took me 5 years to grow it up over my trellis but now the thicker vine trunks are all split open and the leaves are slowly turning brown. So heartbreaking.

What other plants or shrubs may be affected by the cold snap last week? Even my hollies and boxwoods look stressed...

    I cut my Fargesia rufa 'Green Panda' clumping bamboo down to 3 inches yesterday. It should have been hardy from the temperatures but the combination of drying winds killed the leaves. I figured since it will be shooting in a month, it would not only look better, but form up better from scratch versus having to deal with live canes but which have no leaves (clutter).

    I agree with Moni with regard to the vine, wait and see. It's quite different than the once or twice a year sudden growth on the bamboo. My opportunity to clean up safely is now and would be impossible when the new shoots show up.

    I lost the foliage on my Oxblood lily (Rhodophiala), which is hardy to 10F, but I reached -15F. I believe the bulb will be little affected, since foliage would have been dying down by end of March anyway (as I recall).

    My sabal minor palm has leaf burn and the newest spear may be lost, but I think it'll recover over the summer. I believe the several clumps of crinum that I have will be totally unaffected. Being protected by the ground, they survived -25F in NE Oklahoma in 2007 without any issue...shocking.

    I have absolutely no idea about my lantanas, but am hopeful. In Oklahoma, they also survived -25F with a week under 3 foot of snow, but they were better established than mine in here in NWA. We should know something by mid April I would guess? I didn't feel like the ground temps shot down that much to hurt things that were still below the surface.

    I lost some foliage on hellebores (you know hardy to z5 or z4, but due to the abrupt and late cold, new growth and bloom was affected).

    Relatively speaking, I feel that plants were very resilient, but only time will tell, right? I told a gardening friend in Edmund that the tears may begin in June when we know for sure on things.

    Well, I took a tour of the yard yesterday, and I'm afraid I'm gonna lose some ornamentals. Nandia looks bad. Got some parts of the boxwood that's looking dead. Worried about the crepe myrtles and my koran spice vibernum.

    I am concerned about my crepe myrtles also, we took a few out a year or two ago. I am thinking I will go ahead and trim them up and just wait and see what happens. We still may have 12 or 15 crepe myrtles left. I wont loose an sleep if we have to take them out, we have too much junk to mow around anyway.

    I have a hedge on two sides of my back yard. It came with the house... and is way cheaper than a privacy fence. But, what is it? Euonymus?

    As you can see, it has frost damage. First time since 2016. I will trim that damage off, which in itself is no problem I was going to trim it anyway before the spring growth spurt.

    These nandia look terrible, even if they're not completely gone, they will have to be replaced

    Thanks for all the helpful responses. A lot of the plants I mentioned are also on the south side of our house (lantanas, society garlic, some cannas), and are planted next to sidewalks and other stone objects, so I'm sure that's partially why they have come back consistently for 10 years now, but yes, time will tell. We hit -10 F but they were buried in so much snow that I'm hopeful. I recently read an article based on a study that indicated that 9 inches of snow can make a 42 degree difference in temperature: https://mynortherngarden.com/2011/02/04/snow-insulating-power-in-winter/.


    Oh no, Lynn! I'm so sorry about those nandinas. So disappointing.

    Moni, those shrubs maybe look like a privet, but it's hard to tell with the leaf damage. Others on here would surely know better than I do.


    I also have several crepe myrtles, and an somewhat worried about them. I had to take one out this Fall because it was just starting to look bad after sustaining a few years of sunscald on the bark, and then got infested with black scale, so I gave up on it. They just seem to require so much maintenance around here..


    And this is to say nothing about the miles of cannas that we have around here... I have a feeling if they were covered under enough leaves and snow that they'd be OK in the ground.. We'll see!

    the poor Jessamine vine...

    I think my parfuma crush rose bush was taken out by the last storm. It's gone completely black. Told my husband and surprisingly he was all hopeful for me saying "it'll bounce back!" I sure hope so. I got it on clearance at Lowe's about 4 years ago and babied it back to health and it has thrived. It's so pretty! Here is a picture I took last year and just happened to catch a tiny bee at the same time. This is one of my favorite pictures!!

    Roses are generally pretty good at taking minor damage and returning. If *all* the canes are black, it may not though. Leaves, no one cares about..they'll be replaced soon (if it's alive).

    The nursery business is gonna be good this spring. I bet I'm not the only one who will be replacing shrubs and bushes.

  • 5 years ago

    I doubt the nurseries will make a lot off me, we are at a point in life where we are trying to have less stuff to care for.

    Guys I just found this thread. I’ve just been devastated looking at my garden. I’ve trimmed back some stuff. So questioning does anyone think my lorapetalum will come back. They are such beautiful red in my landscape.

  • 5 years ago

    I’ve seen some in my neighborhood that seem to be alive so I’d say there’s hope. Has it put on any new growth yet?

    My plants mostly all survived, but took some damage of course. My dwarf burford hollies almost completely defoliated but are putting on new growth and looking fine. Same with my nandinas. I had to cut the jessamine vine down to about 8 inches above the ground but it’s starting to put on good new growth. Japanese Aucuba also doing ok, as is the crepe myrtle. I may lose a fig (ironically the one that’s been there the longest) and a few lantanas that had been coming back for several years. I also lost and pretty much anything in containers I had been storing in the garage for the winter...

    Thanks greenmanOK. I’ve been holding my breath and most of my stuff putting on new leaves and buds too!!! I love on them almost every day(along with the rabbits and squirrels)!! I just today pulled down Carolina jasmine vines that had covered almost half of my pergola. Made me sick but with new growth at the roots I’m hoping that will give it energy to get going strong again. My nandinas and red tip photinia and lorapetalum seem to be struggling the most.
