Agave americana subsp. protoamericana Gentry is the correct and accepted scientific infraspecific name for this subspecies of Agave americana. It was named and described by Howard Scott Gentry in Agaves of Continental North America in 1982.

I bought this Agave species from an Ebay seller in 2009. It was listed as Agave americana ‘Blue Monster’. He actually sent me two pups. I didn’t take a photo of the smaller one until 2011.

I was amazed at how fast this Agave was growing! When the above photo was taken on December 16, 2009, it measured 8″ tall x 19″ wide!

We made it through our first winter together and the above photo shows it in the backyard of the mansion for the summer of 2010.

I was excited when I saw that after only a year this plant had its first pup. Little did I know what was to follow.

My Agave americana subsp. protoamericana grew like mad! By September 2009 it measured 20″ tall x 28″ wide.

<<<<2011>>>>

Agave americana subsp. protoamericana on 8-1-11, #68-3.

I was getting more amazed by this AWESOME Agave every time I looked at it. When the above photo was taken on 8-1-11, it measured 28 1/2″ tall x 46 1/2″ wide.

By now, this plant, as well as #2, have produced MANY pups. I learned that decorative pots look amazing, BUT… Getting pups out of this pot was insane. The runners that would grow away from the plant if it were in the ground wrapped around the pot. Not to mention the thought of removing this big plant from this pot. The beautiful pot would probably have to be broken. SO, I just left it in the pot. I did repot #2 and it had also been in a slightly curved pot. My neighbor helped me get it out and I knew that I had to put it in a straight-sided pot after the ordeal.

 

Agave americana subsp. protoamericana #2 on 9-22-11, #80-2.

I hadn’t taken a photo of #2 since I bought it until the above photo was taken on 9-22-11. It measured 20″ tall x 32″ wide.

Sometime during the summer of 2011, a friend (Kyle Hall) and I went to a K&K Nursery in Cleveland, MS to pick up some bamboo stakes and the owner had this HUGE Agave and said it was an Agave americana. It was completely different than mine and he gave me a couple of pups… The difference between the two sparked my curiosity so I took photos of the plants and leaves and sent them to Tony Avent of Plant Delights and Cheryl of Highland Succulents. Both told me that my original plant, the one from Ebay, was in an Agave protoamericana, which is a subspecies of Agave americana. It is properly called Agave americana subsp. protoamericana.

The above three photos were the ones I took and emailed to Tony Avent of Plant Delights and Cheryl of Highland Succulents for identification. The first photo is to show how the Agave grows, and the second and third were to show the leaf pattern and striations on the leaf. When a new leaf emerges, it is so tightly wrapped that it leaves the pattern on the leaf. The Agave americana has smooth lines which are shown on its own page here.

Now, folks, I have to tell you that although many Agave species, including this one, were cold hardy in Leland, Mississippi. I saw MANY Agave growing in other yards and along the road here and there and some were HUGE!!! I kept mine in pots because I was not sure how long I would be at the mansion. The estate was in probate.

Every fall when the temps got cooler, I moved all the plants into the sunrooms on the first floor. This was very tricky with the large Agave. I learned how to do it by myself, but in the spring of 2012, I decided to get some help. I went to one of the neighbors behind me, (Cat Man was his nickname) who had told me before that he would help anytime. Well, I knew he was usually half drunk, so I was somewhat reserved about it. BUT, there were two other guys visiting him and they didn’t appear to be drunk. SO, they all three came with me back to the mansion. The other two guys grabbed hold of the pot on either side like I showed them and Cat Man put his arms around the WHOLE plant. I bet he won’t do that again! I will never forget that or how Cat Man and I first met…

OK, I will tell you how… One day, maybe 2009 or 2010, I was working in the backyard. I had left the side gate open because I was in and out. I had a CD playing inside the den and the back door was open. I looked toward the house and there was this man standing by the door dancing… I am not racist and never mention someone as “this or that black guy.” But, he was an African American and he introduced himself as Cat Man. He was also drunk. Umm… There was another man in Leland, also African American, whose nickname was Cat Man, too. He was a blues singer.  Over the years, I made many friends in Mississippi, the majority were African American… Thinking back, maybe the neighbor wasn’t Cat Man… GEEZ! How could I forget? Impossible… His nickname was Cat Man.

As you can see, there is also a pot of Equisetum hyemale (Horsetail) in a pot to the left of this Agave. They were given to me by Augustine Taylor in 2010, a resident of Leland, Mississippi. She had a HUGE, HUGE Agave americana ssp. protoamericana in her front yard with a flower (anyway, it looked like mine). That’s what caught my eye at first then I saw the Equisetum in her yard. I knocked on her door and told her I was admiring her Agave and noticed she also had Horsetail. She eagerly told me I could have all the Horsetail I wanted… What an adventure!!! I am thinking I took her a plant of some kind, but it has been 7 years ago and I am not sure. I don’t know if she knew her Agave would die since it flowered and I certainly wasn’t going to break the news to her.

 

Agave americana subsp. protoamericana #2 on 7-2-12, #105-1.

I kept #2 on a wall along the driveway at the mansion. It measured 23″ tall x 38″ wide when the above photo was taken on 7-2-12. As you can see, there are MANY pups that needed to be removed.

 

Agave americana subsp. protoamericana #3 on 7-2-12, #105-2.

I think the above photo is #3, which was one of the older pups from #1. It measured 16″ tall x 24″ wide when this photo was taken on 7-2-12.

 

Agave americana subsp. protoamericana on 7-2-12, #105-3.

I lined all the pups up on the wall, actually, there was another wall on the other side of the driveway with more.

Agave americana subsp. protoamericana on 6-1-13, #151-6.

After the estate was settled at the mansion in Mississippi, my dad asked me to move back to the family farm in mid-Missouri. He was getting older (83 at the time) and mom wasn’t well. SO, after I sold the mansion, I moved back to the farm in February 2013. I had to give up hundreds of plants including all my Agave americana ssp. protoamericana except the one in the above photo.

 

Agave americana subsp. protoamericana on 9-17-13, #188-4.

It did very well here in Missouri and even started sending up offsets.

<<<<2014>>>>

Agave americana subsp. protoamericana on 7-12-14, #231-4.

As hard as it was to imagine, the Agave did very well in the basement over the winter. It was around 60-65 degrees and very low light but they did fine.

I gave up this Agave but someday I will get another Agave americana ssp. protoamericana. Why? Because they are AWESOME plants. If you have space, and the right location, these are impressive! Keeping them in pots is not a good idea, though. It is Ok for smaller species and cultivars, but not Agave that get this HUGE. You can somewhat control their size in a pot, but the plant will not be impressed and having to move them is very tricky, especially if you have to move them inside for the winter (worse if you have to go up and down steps like I did).
