Any luck with Dyckia in the Texas frozen tundra this year?

[MattTX]

I am relatively new to this genus so I am not aware of many growing around me (Houston TX area). It's hard to get any consistent data on cold hardiness - especially with the 'mutt' nature of many of these on the market. Does anyone have any experiences to share with extreme lows with these?

I have one planted in the ground in central TX - it saw 7F I believe. It was not well established so I'm not sure if it is typical.

This is the 'before' photo from right after it was planted. I bought it from the Cactus King here - hence the ratty appearance. I don't have an 'after' photo yet, but it looks like 2 or 3 heads survived.

Here's an old clump growing in the Montrose area of Houston. I drove by last week and it didn't look good. Nothing close up. I believe it is dyckia plataphylla.

Here are the 'after' photos. It was covered with only a wet towel. I ran out of plastic before I could get to this one. It was below freezing for at least 3 days and saw a low of 7F. Looks like a bloom is about to go up too. This was sold as a 'Dyckia var. Burgundy Ice'.

I left a few out accidentally, they were torched by 4*F and a week in ice.

Barton Springs Nursery in Austin sells a “Hechtia sp.” that took minimal damage if any in the last freeze. They also have a clump of Dyckia in their landscape that took minimal burn. I went ahead and bought a container of the Hechtia. It was probably 15 offsets jammed in a container for $6.99. I split them up to give them room.

Wow, that sounds interesting. I'm trying to only get 'cold hardy' plants now (after the freeze). I have enough stuff to move in when it gets cold. Anything that can survive the sun & heat + the occasional Arctic blast (and not actually be a weed) is a winner!

Hey mean post up a picture and what are your normal winter lows. The the 30’s?

[Meangreen94z]

Here NW of Austin usually sees atleast mid to high 20’s annually. The Hechtia isn’t much currently, here is one container. I’ve heard Dyckia “Burgundy Ice”, and Dyckia Choristamenea are pretty hardy. It looks like the above one will come back

[Meangreen94z]

None of these were in outside but here’s a few more of mine.

They look healthy! They will no doubt be pot fillers in the future.
