Agave univittata Haw. was named and described by Adrian Hardy Haworth in Philosophical Magazine, or Annals of Chemistry, Mathematics, Astronomy, Natural History and General Science in 1831.

The species name, univittata, means “one stripe”. 

The genus, Agave L., was described by Carl von Linnaeus in the first edition of Species Plantarum in 1753.

Plants of the World Online there are 280 accepted species of Agave (as of 10-10-21 when I last updated this page). Many species of other genera have been moved to the Agave genus, such as Manfreda. It is a member of the plant family Asparagaceae with 120 genera. Those numbers could change as updates are made on POWO.

POWO was having somewhat of a glitch when I updated this page on 10-10-21. It says Agave univittata is a synonym which is apparently not correct. BUT, I checked with the World Checklist of Selected Plant Families (also from Kew) and it says Agave univittata is a synonym of Agave lophantha. That was confusing, so I sent an email to the senior content editor. His reply was the data on POWO and WCSP were the same. Ummm… He also said if the name is not on the International Plant Names Index, it wouldn’t be on POWO. Well, both Agave lophantha and Agave univittata are on the IPNI… Of course, the IPNI doesn’t say which name is accepted or not, it is for plant names, authours, and publications. OH, the editor did say it is a general agreement that Agave univittata is the correct name. He and his team at Kew are working very hard, so I trust it will all work out eventually (probably very soon). Just letting you know in case you click on the link to the species (below) next to POWO and it says Agave univittata is a synonym… And why it doesn’t say what it is a synomym of… I have no clue why the WCSP says A. lophantha is the accepted name. Well, someone screwed up…

I bought this Agave in July 2016 from a local Amish Greenhouse, I think probably Mast’s. Even though I always say I am not going to buy plants without labels AGAIN, I always wind up doing just that. This Agave was one of them. I looked off and on for its ID but decided I better make a decision so I can make this page (on December 1, 2017).

I always start out looking at images online when I have no name and clicking on the photos that look similar. This time the first photo I saw that looked similar to my plant led me to a website by Stoney Creek Cacti & Gifts.  I scrolled down their Agave selection and found the one that looked like mine. It said the name is Agave lophantha splendida. Well, Agave lophantha is a synonym of Agave univittata.

It is so much easier to send photos to an “expert” to ID, but I always try and do it myself first.

The above photo is what it looked like after a winter in the house on May 31, 2017. It didn’t get enough sun and it looks like the leaves stretched. It really doesn’t even look like the same plant.

The leaves of this species grow to around 15” long and are thinner than most Agave. The leaves are rather flat with a thin white edge and white teeth. The needle on the tips of the leaves is brown.

I have had no problems with this plant. Photos online show plants with longer leaves, so maybe they are supposed to look like this as they get older. This is a smaller Agave, growing no more than 12 to 18″ tall, so it is much more manageable than a few of the larger plants I have grown.

<<<<2018>>>>

The Agave univittata survived the winter in the house in my bedroom and was very glad to get back outside for the summer.

On July 12 I decided the Agave univittata needed to be in a larger pot… I had moved the plant table from behind the shed to the front porch and the potting table to the back porch.

Agave univittata in its new pot on 7-12-18, #476-3.

I put it in a 9″ diameter x 6″ tall pot. Now its roots can spread out a little more. Smaller Agave are so much easier to work with than the larger growing species.

The Agave univittata is now on the front porch. I don’t think it has really been getting enough sun…

<<<<2019>>>>

Agave univittata (Center Stripe Agave) on 5-25-19, #576-4.

The Agave univittata made it through another winter and I decided to put it on the back porch for 2019. It will get full sun all day here and maybe it will do better and begin to look more like what an Agave univittata should look like.

Agave univittata (Center Stripe Agave) on 6-19-19, #592-1.

The Agave univittata is doing very well and enjoying the full sun on the back porch on 6-19-19.

Agave univittata on 10-11-19, #639-4.

I had to move the plants inside on October 11 because an “F” was in the forecast. I took one last photo of it before moving it inside for the winter.

<<<<2020>>>>

Agave univittata at 13 tall x 27 1/2 wide on 10-15-20, #747-3.

I kept this plant in a sunny part on the front porch for the summer of 2020. It seemed to have a few sunburn issues on the back porch in 2019. It did well, as usual, and measured 13″ tall x 27 1/2″ wide when I brought the plants inside for the winter on October 15.

<<<<2021>>>>

Agave univittata (Center Stripe Agave) at 17 1/2″ tall x 25″ or so wide on 8-17-21, #826-4.

I took measurements earlier this year, so this plant measured 17 1/2″ tall x 25″ or so. When I added the measurement to my journal, I noticed it was 27 1/2″ wide in 2020. I went back to recheck and noticed I had neglected to consider the oldest leaf on the bottom hanging downward. I kept it on the front porch in 2021 because it didn’t seem to like the intense sun on the back porch last summer.

I will continue adding more photos as time goes by.

Even though Agave lophantha is a synonym, there are still many websites that use that name. Agave lophantha ‘Quadricolor’  is very popular.

    Hey there, I think you might actually have an Agave funkiana ‘Fatal Attraction’. I have a nearly-identical plant and was looking for the ID-yours was the first that came up as a match, but I wasn’t convinced by the univittata ID (they’re closely related, though!)

    • Hello RL! t was a tough one for me to ID. The way it looked when I brought it home and the way it looks now is so different. I will check out. I will check out your suggestion. Take care and thanks for the comment!
