| Last year was really a severe winter for my area, I lost a lot of plants. Some to be expected, some that should have made it. Lost a few daylilies, a variety of shasta I can't remember the name, a few other perennials that were supposed to be hardy to zone 5 or so. I'm in what is now considered zone 7, used to be zone 6. I guess that is due to warming? Anyway, harsh winter, no surprise that my cannas didn't make it, although I mulched them very well & they were in a protected area in a corner by the foundation of my house. Not one canna survived. Calla lilies all returned, most bloomed, & I have them scattered. No extra mulch, not protected areas. Who knew? Just found some oxalis that has come back, very late in the year but I had definitely given up on it. One was listed zone 8 when I bought it. Both varieties of Hymenocallis bounced back, although not many bloomed, but they were zoned 7b & 8. Salvia black & blue is sold as an annual here. Most have not returned, but I have one clump that has returned every year, & it was back this year. I've been pleasantly surprised at what has survived, I really didn't expect it. |

| Salvia guaranitica is a tough customer. I've had a clump of "Black and Blue" return for several years, including after lows to -19F last winter. Full sun, mulching and location in a well-drained area help. Out of all my supposedly tender plants (such as dwarf palmetto, Amorphophallus konjac and Mirabilis longiflora) only one croaked as a result of the harsh winter - Texas tarragon (Tagetes lucida). It wasn't a huge loss since I hadn't been able to get it to flower here. |

| Well since oxalis are related to some of the weeds on the planet IMHO, it's not surprising they are tough overall. I too was surprised my Calla lily survived here with no special care, but it is growing in a natural wetland area and had snow cover during all the freezes (very lucky) and some surrounding vegetative cover like Scirpuses. (Scirpii? haha) Much as cold winters are a downer, it's good to have one once in a while to stay realistic about climate, and learn about plant tolerances. I let my Euphorbia characias self-seed around the garden and one clump showed much less damage than the others...should I introduce it? I have been meaning to try Hymenocallis so your report is encouraging. Do you remember which ones survived? |

| I have Ismene, Sulphur Queen hymenocallis. I'm not sure if the name is for the same plant, or if Ismene is one variety & Sulphur Queen is another. I know I have 2 varieties, they look different & bloom at different times. Which is which, I can't say. One has multiplied quite a bit & has much larger foliage, the other one returned, but has never multiplied & I think I lost on of the bulbs. Sorry I can't help more than that. |
