Probably not hardy in your zone. It is said to be hardy to zone 6 but I imagine that would be pushing it too.

Fully hardy here in zone 6. Came back last spring after a very cold winter with no snow cover. They are, however, very late. Give them at least two more months. Also, you must leave the old growth over the winter to help protect them and avoid bringing moisture into the crown.

Last year when I bought them the company said hardy to z5, now they say z6.

I did leave old growth on over the winter and its still there.

We had snow cover the entire winter, so I will keep my fingers crossed.

I bought wild thing two years ago and it did come back. I'm in zone 5 between a and b, however with all the moisture meaning snow I haven't seen any sign of life either. I'm going to give it more time, don't have anything to put in its place anyway.

I too bought wild thing last year knowing it might night come back. So far no new growth has shown but I am hoping. However, I like it so much that even if it does not survive the winter I will just treat it like an annual and plant every year.

Not hardy here. I have tried several different years in several different garden spots and never had any luck.

I'd say zone 5 (even zone 6) is very generous regarding the hardiness of this plant. Salvia greggii doesn't even winter over reliably in my zone 8 unless drainage is superb. IME, any combination of wet winter soils combined with too much cold will be fatal. This plant wants extremely sharp drainage, lean soil, full sun and minimal moisture -- all year.

OK - maybe it's not meant to be in z5. I grow many other salvias quite happily, and since my garden is on a gentle slope, I always have excellent drainage. (too good in the summer)

Ah well, she was pretty while she lasted.

Want to amend my previous post. After checking, I see that it's S. 'Black Cherry' and S. 'Ultra Violet' that have come back. No sign of life on the three 'Wild Things'. I bought all three from High Country Gardens, and after last season's return of the first two mentioned, I felt confident enough of HCG catalog info to try 'Wild Thing' last year. It is still, however, very early; last year the first two didn't show signs of life until I had completely given up on them and were about to pull them out--some time in mid May I think.

I've given S. greggii hybrids a couple of tries here in the northern part of zone 6, and had none overwinter, though I've gotten other supposedly tender Salvias to make it for at least a few seasons.

High Country Gardens has a lot of interesting stuff potentially worth experimenting with, but in general I'd add at least a zone to their projected hardiness ratings (i.e. with plants they describe as hardy to zone 5, I'd expect survival only in zone 6 or above as a general rule).

Prolonged cold wet weather in the Midwest and Northeast and damp winter soils are tougher on perennial survival than the conditions which apparently prevail in much of the Rocky Mountain West.
