I can't answer you on whether there is a Kalanchoe that is hardy in zone 8, but the one I have certainly isn't. I had forgotten about this, but when I set my first plant out for a summer, she dropped tons of babies into the lawn, the big pea-gravel area with the picnic table, and even the cracks in the driveway before she died. They all disappeared quite quickly when the frosts arrived and were never seen again.

I'm not sure that's the same plant I have - the leaf shape is almost right, but I've never seen a hint of pink, and the purple markings stay on the undersides of mine's leaves, not the top. The genus Kalanchoe has over 100 species, though I don't know how many of them are kept as houseplants. It's probably a safe bet that it won't survive a freeze, though.

They get purple markings underside or all over, when it still feels some cold..cold stress reaction. Then they turn all green when full swing warm weather comes about.

Mine must be confused... the house has been in the 50s regularly this winter, yet they're greener than I've ever seen

I'll defer to your expertise, Tarev. I've only kept the one type, and they obviously haven't been treated right this past year.

Oh yeah..plants are temperamental and confusing at times! Just today, I have been moving my succulents outdoors, repositioning them here and there..trying to remember which ones prefer more sun or more shade..

Now i don't know what to think mine turned colors and got stripes or a pattern on it in the sun.Now that it's inside the growth that happened over the winter (my plants all grow all winter) we don't have much cold weather and i don't think they ever realize it's time to take a break and not just my succulents.MY Hoya's,lipstick plant's, prayer plant,rhipsalis's,jades etc... all have new growth well not so new now but all happened during the winter.Maybe i keep my house to warm.My granddaughter has lived here since she was born so i do keep my house warm and succulents under grow lights.

Maybe i need a cool/cold room but they don't seem to suffer.The growth slows just never seems to stop.I do water less and don't feed in winter.

Speaking of the baby she's trying to type yall a message so got to go. will come back later
