"Hot Lips" isn't very hardy. I live in zone 7 and I lost it all the winters.
You can planted them in full sun, and sandy soil, like other Salvia microphylla.

They are both hardy throughout zone 7, so go ahead and get them in the ground. Plant in well-drained soil in sun ('Maraschino' seems to appreciate a little afternoon shade). The big thing to remember is not to cut down the dead winter branches till you see new growth appear in the Spring.

Thanks ladies.....I have no sandy soil at all....I do have rich soil thats been super ammended over the years from the Carolina red clay.....I think I might plant Maraschino and keep Hot Lips in the pot and move her into the greenhouse over the winter. lol

Ladies?

If the crown stays dry enough in winter I think Hot Lips will be hardy for you. Last winter mine suffered damage in zone 7 when temperature dropped to about 3 degrees in January and nearly that low at the end of February. Still, 6 of 8 eventually did return, albeit slowly.

I also live in the cusp of 7B/8A in Olympia, WA, 60 miles south of Seattle. Low temps the last few years have been in the 12 - 18 range. I have been growing Hot Lips for a few years and they usually die out if I leave them in the ground. Despite the wet winters I usually don't lose plants that are fussy about winter drainage because my soil is clay-free. Some greggii/microphylla types do come back just fine so I'm not sure what the difference is.
