It's a little yellow/green but I would still say Blue Glow.. Just because of the reddish margin and the marking inside and outside the leaves. Blue flame does not have such strong marking/design on leaves and leaves seem softer..

But then again, I have been wrong before...

I was thinking Blue Glow too;).

Tomorrow morning I'll post a picture of a blue glow agave pup and a pup of this plant. There's so much difference :)

It does look very greenish and somewhat scorched for a 'Blue Glow'. Perhaps it is a 'Blue Glow that needs some afternoon shade and more water, and see if it needs repotting. That might bring back the blue. Is certainly not 'Blue Flame'.

A. 'Blue Glow'

Another possibility would be A. mitis var albicans 'UCB', A. mitis used to be known as A. celsii. var albicans is also used for var albidior. The name recently changed.

Here's a picture of the plant with two of its pups. The fourth (black) pot is a blue glow agave pup. The colors are very different. Also, blue agave got some thick leaves whereas the plant in question got very thin leaves.

hoovb, the leaves of the plant you mentioned are much wider.

I need a favor. If anyone got blue flame agave, can you post two pictures for me. One taken from the side and one from the top?

I think we can rule out 'Blue Glow' with all those pups;).

'Blue Flame' from the side

Not getting a 'Blue Flame' vibe from your plant, Joe. You are in SD where availability is better than most places, so what about 'Blue Ember' or 'Blue Emperor'?

Could it be Green Glow, that one was generated by Rancho Technologies which is located in your area. Where did you get your plant from?

hoovb, this is blue flame from the top.

Up till 5 mins ago I had never heard of blue ember nor blue emperor agave. I thought you were joking. I looked them up. Beautiful plants. The leaves shape seems to be very similar. Not the color though. Plus, those have teeth but mine don't. Thanks.

Alain, the person I got it from said it was blue glow and I disagreed with him at the time because it was different from the blue glow he had in his yard. I told him I thought it was blue flame instead but he insisted that he had separated it when it was a pup from a parent blue glow.

I didn't mind at the time because I love blue glow and I didn't have any blue flame agave. But now I really want to know what's the name of this agave :)

Alain, that looks spot on.

Now I'm confused. Ok 'Blue Glow' is a hybrid of A. attenuata and A. ocahui and 'Blue Flame' is A. attenuata and A. shawii. What I've read 'Red Margin' is A. aatenuata and A. shawii so technically it is 'Blue Flame', but just a cultivar of 'Blue Flame'. That part I get, but why do people keep calling 'Red Margin 'Blue Glow' when technically it has the same "blood";) as 'Blue Flame'. Am I confused or read something wrong? Maybe I'm reading too much into it;).

'Red Margin' is not solitary so that explains the pups;).

'Blue Emperor' is on my list. That is one beautiful Agave;).

yes it is confusing and I did not dig too deep into the Red Margin make up to know the answer. One could read at times that it's an hybrid of Blue Flame but the other parent is not discussed, or as you say just a different cultivar. Or a different hybrid using different attenuate species...Hopefully someone can share that info here (as well as confirming the ID:).

Well regardless my vote is for 'Red Margin'.

You nailed it, Alain. Bingo Red Margin it is. :D

Thank you so very much!
