Nice report. Chilopsis linearis is much hardier than most references think. I know of someone in Pocatello, ID who was successful with it for a long time.

I have been growing Chilopsis linearis in Boulder, Colorado, for over 20 years. They have survived -24 F. They do not become very large, due to the short growing season, but they survive our coldest temps with no trouble. Just another cold climate plant which survives in hot, dry areas. (It probably does not occur this far north naturally because young plants can not survive the cold. Old, established plants do fine; same applies to Cupressus arizonica, which survives very cold weather if it is well established.)

Yeah, you're both right about desert willow. In the wild, it occurs to about Bernalillo, NM, which can get very cold now and then (not sure how cold it got this winter, but probably in the -15 to -20 range). There are a few locations around Santa Fe with some beautiful, large specimans, but I'm not sure at what size they were planted.

Good news from the southern end of the state.
Lots, and I mean lots, of palms are pushing up green fronds. Crape myrtles are starting to bud on the branches and rosemarys are pushing out new leaves high on the plant.
Still have lots of brown pines but we're hoping they'll push out new needles soon.
Things aren't looking as bleak as we had feared.

That's great news nmgirl!

I agree that things are not looking as bleak as we had feared.

Here is some follow-up to my original report:
-- AZ barrel did succomb to the cold it turns out
-- Desert agave that was killed was survived by some pups!
-- Believe it or not, my rosemary also survived!
-- Still waiting to verify plight of Mimosa (planted last summer), Fig, and a few others...
