Default Agave arizonica

I think this is Agave arizonica. Its a slow grower. I bought it several years ago thinking it would make a companion for my A. pelona. The A.pelona died mysteriously a while ago. Is arizonica still considered a natural hybrid? I suppose alot of Agaves are. Is pelona related? Its been awhile since I have seen pelona.
Thanks for any info

Nice specimen of a rather difficult species to cultivate!

And no, Wes; A. arizonica is not related to A.pelona! (But it sure looks like it could be!)

By the way, Wes, I might be able to conjure up an A. pelona for you if you hold your mouth right!

Found this on the net.. Where did I put my Gentry book?
Whoa.. I better take better care of this one.

National Collection of Imperiled Plants

Agave arizonica was first discovered in 1959 in the New River Mountains of Arizona (Gentry 1970, 1982). It has been described as one of the rarest and most beautiful agaves in Arizona. The Arizona agave is a member of a prestigious family of plants, the Agavaceae. Within this family are numerous century plants that have been cultivated by humans for food, fiber, and alcohol uses.

The Arizona agave is considered to be a hybrid, reportedly from a cross between Agave chrysantha and A. toumeyana v. bella. This means that A. arizonica may be just starting down the path of evolution. (Nabhan 1989, Hodgson & DeLameter 1988, DeLameter & Hodgson 1987a, 1987b).

No doubt!

A very tricky to grow but very special one. I have one I bought many years ago, back when The Desert Botanical Garden in Scottsdale, Arizona used to sell off their excess acsession stock. It still has the original acsession tag! I very carefully divided it a year and a half ago into five plants. After two full seasons of growth, the plants are just now barely re-establishing. I am very lucky I didn't lose them all! So this species definitely falls into the "If it's happy, don't mess with it" category.

Sir Monger
thats a possibility.
Although I have refused many superb looking Agaves recently.. they take up so much room, I might be interested in a Pelona.
You probably are seeking the elusive Hechtia Nova in trade.. Sorry.. I don't have that. A fancy Dyckia? hmmm don't have many of those. a Deuterchonia..hmmm?

Oh..
The last born will be here next week. He will be looking for a job. He may be able to help to clean out your well stocked refrigerator.
ya know.. I had a dream last night about agaves.. when I woke up.. I was in a trance like state and I walked outside..straight to this small greyish plastic pot.
Went back and grabbed my iphone to document.. I felt like I was on one of those 'searching for ghosts' shows on tv.. I heard voices.. (probably my neighbors) saying.."get some clothes on"

whatcha think of these pictures?

Thumbs up

Sure have a lot of 'em! Maybe it's time to spread the wealth around a little; you know, with the recession & all...

Prime the pump a little... trickle down theory...

Especially since you hate Agaves and all...

Let me set the record straight. I do not hate agaves.
Was it not I who brought up the controversial topic of didgeridoos?

It's funny that this agave is hard to propagate, I just mentioned that in another thread yesterday about mine. Assuming mine is the plant in question. Mine does not seem to have the red along the leaf edges as much but there is color there. I have 2 specimens, one of which was just recently dug up and put back into a 15g pot, and is growing some very small leaves which may indicate it is ready to flower. I was able to get 2 pups to root this last summer and they are doing well. I'll get a few pics up when I get home so maybe someone can positively I'd my plant as A. arizonica.

I think those look more like A. pelona. Hard to tell, the pics are a little fuzzy. Can you take a shot from a little further away?

Greg...I was trying to pull a fast one on the monger...
The pictures you are asking about are of a plant I own labeled A.pelona.
Can't remember where I bought it... The pictures I posted at the beginning of this thread are A.arizonica (I think).
They are different plants.
I took the picture with my iphone
If my A.arizonica is really arizonica... mine pups alot.

Here are some shots I took tonight of the plant (s) I have.





And the one I believe is getting ready to flower.

I hope I did not apear to take over the thread.

Default Flowering A. Arizonica

Nice plants, Keith!

The one plant definately does look like it is getting ready to flower! Watch it closely and take care of it! Agave arizonica is extremely rare and considered endangered. Your seed would be much appreciated around these parts, I'm sure! Thanks for sharing the pics!

Could these plants be A. ocahui? They look very similar to the images I have seen from more than a few online vendors.

Question

Hi Keith!

Superficially, Agave pelona and Agave ocahui look a lot alike. Agave pelona, when well grown, has a unique bright green, almost glowing coloration to the leaves, with ruby colored margins. It is a strikingly beautiful plant when at its best. Agave ocahui is a deeper green with lighter margins, although seedlings can be quite variable. Both of these species have smooth margins with no teeth. They both top out as about 2-3' balls.

Your plant has the classic tiny teeth of Agave arizonica. However, Agave arizonica rarely gets taller than a foot or so. I assumed your plant was in a 1 gallon pot and starting to bloom. If it is actually in a fifteen gallon pot then it is probably way too large to be Agave arizonica. If it was in a one gallon pot, then this would be about the right size for a mature Agave arizonica. This is a rare and seldom seen species. You are living very near it's in situ location (up near Black Canyon), so you have a great opportunity to mimic it's requirements perfectly!

Well, the smaller pups I have are in 1g pots, they are at most 6-7 inches tall. The one that looks as if it may flower is in a 15g pot and is maybe 12" tall by 18" wide. It was just recently dug up and potted, then I realized it was putting out very small leaves. All of the agaves I have seen flower at the DBG have had a growth spurt of very small leaves before shooting up a stalk. We will just have to wait and see.

The one in the front yard is really a smaller plant, it is clumping and getting wider but not taller. I will definitely leave this one alone.

I hindsight, had I known what it was doing, I may have left it to grow in the ground. Is flower dissection the only true way to get a positive ID?

The Agave Xarizonica at the show and sale this last weekend in Los Angeles did not sell. What is the taxonomic status of this taxon?

The Flora of North America lists it as Agave x arizonica.
