I'm in MI, and our temps have been getting down to the 40s, 30s, and 20s lately.
I know S.purpurea purpurea is an MI native, so obviously the temps aren't that big of a deal for a mature plant--I'm just wondering since mine is immature.
Same goes for my D.rotiundiflora.
I'm assuming they're fine,but I figured I'd ask.
I was leaving them out, but lately I've been bringing them in and keeping them on my sill just to be safe.
They appear healthy so far--nice and green, no wilting or evidence of damage.
Also, I have a VFT which I got several months ago, and which is more established, but probably less than a year old. I'm keeping that inside for now...
