I had a cycad outside this year unprotected. Had to bring it inside as it started browning with temperatures slightly below zero celsius. It might not be the same variety as your, but it doesn't seem like its a hardy plant at all.

That's all you do for the Sago, Tim?
Are lights controlled by a thermocube? or you just plug them all in at night when it gets colder?

Interesting that the Agaves weren't frozen solid like the Aloes.

So you're done.... 😆 😆

Barb

Wow, looks good. A little late to finish protection, lol!

Tim, are you eventually going to try those A. lophanthas in-ground?

Hi Barb,

no thermocubes...........I'm in the dark ages and still use the 'manual' method. 😀

I'm sure the Agaves were frozen solid but Agaves are not as succulent as the Aloes.

Hi Cameron,

I experimented with Agave lophantha when I lived in Rhode Island USDA z6b and they would survive the warmest winters when sited in a warm microclimate. They would probably do fine if you buried them in dry leaves and placed a cover over the leaves to keep the rain/snow off them (no supplemental heat). They don't need any protection until the temps drop below 20F. The 10F to 20F range is when they get iffy......a single night down to 15F will likely not hurt them at all but 10 nights in a row down to 15F might be another story. Lophantha seemed to be one of the fastest growing and most tolerant Agaves to moisture.

Here's a old photo of my Rhode Island lophantha.....RIP (September 7, 2002).

I experimented with Agave lophantha

I also have in the past, they lasted a couple of years here. I think I will try again in the future. Very nice agave Tim. 8)

Tim... Ive left all my Agaves in. All look ok except Agave Gentryi which has taken in water and damage. The weather here has been shocking. just non stop rain

I will not even contemplate Agave Lophantha after mine nearly perished in my greenhouse. I did foolishly water it and it must have been only 3-4degrees of frost that done the damage.

Andy,

the Agaves are probably not that happy going into winter in your area due to your lack of sun and excess moisture. I can only imagine they will be less hardy in your area. What's the best performing Agave in your area (outside)? I may want to try one here!

Aaron,

it's nice to hear lophantha actually is marginal in your area.....your cold!

Tim... Agave Montana is the best performer for me. Seems to accept semi shade quite well. Agaves Neomexicana, Parryi, and Havardiana should be ok in our climate.
I do have an extensive window sill collection if that helps... some I may try out one day 😆

nice Agave collection Andy! :headbang:

Tim, maybe you should look into a lophantha cross. I remember seeing some for sale before. Perhaps a cross would add some more cold hardiness!

A couple of years ago I got agave plant that I couldn't identify yet. It had like a couple of dozen offsprings planted separately. So I've got a chance testing their frost resistance. So I left a pot with the smallest ones in my unheated GH and these tiny agave plants have being keeping there completely solid frozen for a month (a min temp outside was minus 27C). A week ago those offsprings were taken in and they look like they have survived! Yes, they were cold damaged but started growing already!

Since I can not identify the plant anyone help me with identification? And a picture of the survivors... Enjoy!

-27C survivors in an unheated GH !!!! 😯
Wow, those are keepers!
