I've a salvia 'San Carlos Festival' that has overwintered (24 inch container) for several years.

Besides that one, these overwintered from last year and they're in containers.

Ordered 3 agastache 'Red Happiness' from High Country Gardens and planted all 3 in a 24 inch container. This spring I was so happy that at least one survived and it's big (stems and green leaves). Don't remember if buds are showing yet. That's wonderful, as I wasn't going to order anything else (ever again) from HCG after getting plants in 2019.

Ordered from Bluestone Perennials an agastache 'Firebird' that was growing in a 20 inch container, along side of salvia 'Raspberry Royale'. Firebird showing new green leaves. Not sure of the salvia in the pot if it survived.

Bought locally at Kroger's 3 one-gallon pots of agastache 'Kudos Gold' and planted in a large container tub. One big one overwintered and have 2 smaller plants that overwintered.

Bought locally at Kroger's 4 small plants (4 pack tray) salvia 'Victoria Blue'. Planted them (along the sides) with salvia 'Rockin' Fuchsia' (cnter) in a large container tub. Since I didn't think they would all survive the winter, started pulling them out earlier this spring. Today I noticed a nice sized Victoria Blue with buds and some smaller VB plants, and where Rockin' Fuchsia was planted, I'm pretty sure I saw a couple green leaves.

In another large container tub (black nursery pot), salvia 'Amante' was planted with 2 salvias ('Elk Orange Spires' and 'Scarlet Spires'). I didn't think they'd overwintered, so I started pulling them out and today I noticed 2 green leaves where Amante was planted.

Ordered 2 'Elk Raspberry Moose' from FBTS and planted (one or two) in a 24 inch container and today I noticed some green leaves on one.

Three Bee Balm plants that I knew would overwinter, did. 'Sugar Buzz 'Cherry Pops' I ordered from Romence Gardens in 2018 has overwintered since then; 'Balmy Rose' that I got locally in 2018 at Meijer's and overwintered since then (starting to bloom) and last year, I got 'Fireball' from Meijer's and is doing great with buds.

Planted a coneflower (have to check the tag this week) in a 20 inch container with salvia 'Snow Nymph'. The coneflower is doing good and showing green leaves. Also more of the same coneflower seedlings showing. Haven't seen any seedlings of the salvia. (I knew the coneflower would overwinter).

I can't remember what else overwintered from last year. Later this week when it's not so hot as the next 2 days (especially Tuesday) are going to be, I'll try and check all the containers.

I live in an elevated house that has a laundry room on the bottom floor. Every plant that I do not think can survive under 35 I put them in there. To prevent frost I move the plAnts under the house or put them in our hangar. The rock in salvia weren't looking so good beginning of winter, but they have really taken off. I might have a problem with room this year since right now I have the saucy salvia and those can get pretty large, but supposedly can't handle the cold too well. Red Porter weed is one that I do not believe can even handle 36f.

Eric,

I'd think that in zone 9a that you wouldn't have to worry about frost.

By elevated, do you mean it's a 2 story house?

The house is on top of cement columns with a cement bottom. We get about 10 frost days every winter.

I was surprised, puzzled and pleased to see all the Salvia viscosa returned. (Of course, they might be misidentified.) They were seedlings last year and didn't get large enough to bloom before winter arrived. I figured that was the end of them since they're listed as hardy to 8a or so, while we're 4b/5a. We did have some snow cover for part of the winter (very unusual for us). There wasn't any snow in April, though, when the single digits torched quite a few other plants that typically aren't bothered by the cold.

Mystic spires over winters well in my usda 8b, never lost it's leaves. Very pretty plant in bloom.

I am a little confused by the saucy salvias in the database. When i bought them it said zone 10. Im in zone 9a. The database says they are good till zone 7. Anyone know where the zone 7 came from?

Eric, the first year or two that the Saucy Salvias were marketed by Southern Living and Sunset, they were promoted as being hardy to zone 7. They were wrong! Luckily for me, my local Home Depot lived up to their plant guarantee.

I'll change the hardiness to 10a for the 3 Saucy salvias.

I noticed Agastache Heatwave blooming yesterday. Week ago, I'd noticed some small agastache plants growing in the container where I had Heatwave and I thought the main plant had died, but it's growing and blooming.

When I thought it was dead, I wanted to get another one, but I didn't find any place that had it online or locally. It's wonderful that it came back in the 20 inch container I had it in last year.

In the 24 inch container with salvia San Carlos Festival, salvia Red Velvet overwintered and has been blooming. Love that bright and rich red color.
