Sorry about that,your right PARRYI-Here are some pics of parryi and other agaves.the skinny leaved one is blue tequila agave,not sure of cold hardiness,supposedly 0F-

Hi Wim
It is interestingly, maybe not parryi,maybe not cold stable form.
Very small for identification

Not all parryi are extremely hardy. Some are only hardy to around 25-30F while others can take below 0. For example, parryi var. parryi and parryi var. neomexicana are some of the hardiest.

I will just need to wait and see,things are drying out now that they are covered.I have a small one of these and it is fine but only because it was not well rooted and was much drier than the others,so,wet soil was the main problem,I think these will pull out of this as centers look solid,but the tequila agave is probably toast however it does have a baby that I will kkep gravel over until things warm up next year,thanks guys.

looks like some form of americana to me?

Hi
Yes I agree with Aaron.
Josef

The one in the first pic is blue "tequila" agave,2nd Parryi(the one with 2 plants) the third was a freebie thrown in on another order,this agave and another small one similar to it have more thorns than my americana(not pictured)-soil moisture is the problem,my other small agave that is not rooted as well is unfazed by the cold so far as it is much drier

Thats makes sence, could also be first year in the ground and not frost hardened yet?

Hey D-Z,after going back and looking these up on e-bay,I agree with your original observation,as far as them possibly being some form of americana.I looked at a lot of different varieties of parryi and even when they are young they look like,surprisingly enough,parryi,however these would look a lot better if they were actually dry going into winter as one just like them is fine, that was very dry.So,what to do?I ordered an A. havardiana(15"across,hardy to-20F and a 11"across parryi)I am also going to order the blue form of A.parryi,hardy to -20F and some other mountain barrels hardy to at least zone 5 or more,my one hold out that is possibly not as cold hardy as the other succulents is Y.aloifolia,I wonder if a joshua tree is more cold hardy than Y.aloifolia,anyway I guess the point is to get more cold hardy cactus that I can just rig up something to keep them dry and not have to heat during sub zero as I have enough cold hardy palms to protect as it is.These agaves will definitely see colder temps this winter than the temps that mushed them,so we will see if drying out more before the coldest temps hit is enough.Thanks for your comment DZ and Josef,any thoughts?

Joshua-trees are very cold hardy, but need to be coverd when they are young. They also need good drainage and need crowns protected from most wet weather until they can form nice tight spears. I took a towel and covered their crowns during snow storms and very cold weather when they were young. As they get older this becomes less necessary. Also remove the towels after the snow storm has passed becuase they will need the air flow around the crowns.

PS Some individual plants are just more cold hardy then their brothers or sisters, so don't give up if you lose a plant. I lost every j-trees that I first tried, but have learned a few things sence 😉 .

I will keep a rain shelter over mine if and when I buy one,which I am sure I will! I will buy a larger plant with a foot of trunk as I am realizing that larger plants(protected the first few years at least)are more cold hardy.
