I figure if I list all the negatives, I might as well list some of the positives!
I'll list here some of the better things to come from the winter:
Most of the cacti survived: Cylindropuntia kleinae (first time ever!), Opuntia phaeacantha (4 different types!), Echinoceri including triglochidiatus, rechenbachii and coccineus, ALL of my Escobaria (vivipara, missouriensis, sneedii), M. poppigii, A couple Sclerocactus, Opuntia erinaceae v. ursina, and EVERY form of Opuntia basilaris I have (It's my favorite, I have about 7 different types, and 3 more that I've just planted!)
Yucca elata continues to thrive, as does Y. baccata, Y. harrimaniae and Y. neomexicana. Out of zone palms seem to have survived (T. fortunei and R. hystrix). Out of zone Rose of Sharon (yes, my area is too cold, normally, for Rose of Sharon!) seems alive, as does Paw-Paw. The bamboos (aureosulcata and nuda) seem to be at least root-hardy!
Magnolia virginiana v. australis (evergreen) has kept most of its leaves...
I think that's all!
Cheers.
