Agave americana L. is the correct and accepted scientific name for this species of Agave. It was described by Carl von Linnaeus in Species Plantarum in 1753.
Plants of the World Online by Kew (Royal Botanic Garden) lists 268 accepted species of Agave.
I was given my two Agave americana plants from the owner of K&K Nursery in Cleveland, Mississippi in 2011. When someone gives me a plant I usually name it after them, so I named this plant Agave americana ‘K&K’. I had bought an Agave americana from an Ebay seller in 2009 but the leaves were completely different. The lower leaves of the Agave from K&K curled under and had smooth lines along the leaves. The plants from the Ebay seller grew upward and had distinctive patterns on the leaves.
Information on the internet just made it more confusing because they were wrong I sent photos to Tony Avent of Plant Delights Nursery and Cheryl of Highland Succulents. Both of them told me the plant from Ebay was an Agave americana ssp. protoamericana the one from K&K was Agave americana.
As you can tell from the above three photos, the Agave americana grows much different than the Agave americana ssp. protoamericana. The leaves have smooth lines and curl under.

We made it through our first winter together with flying colors and the Agave americana was glad to be back out in the backyard at the mansion.
Common Name: Century Plant
Family Name: Asparagaceae (formerly in Agavaceae)
Origin: Mexico and southwest Unites States (Arizona, New Mexico, and Texas
Zones: USDA Zones 8a-11 (10-40 degrees F.)
Size: 3-6’ tall x 6-10’ wide
Light: Full sun to part shade.
Soil: Prefers a very well drained soil somewhat on the dry side.
Water: Average. Mine get regular water during the summer but I seldom water while indoors over the winter.
Propagation: Can be grown from seed. They produce many offsets so you will have a good supply to pass along.
Although the Agave americana is a native of Arizona, New Mexico and Texas, they are grown worldwide as an ornamental. That has led to them becoming naturalized in many other countries. There are four accepted subspecies, that I know of, and several popular cultivars. A few have received the Royal Horticultural Society’s Award of Garden Merit.
When I moved back to the family farm in mid-Missouri in February 2013, I had to give up most of my plants, including the largest Agave. I did bring one of its pups, though.
The name Century Plant is a little misleading. They typically live 10-30 years and flower only once at the end of their life. The plant dies after flowering, but by then, it will have produced MANY pups. Plants grown indoors rarely flower.
The Agave americana did very well in mid-Missouri although it is in a pot because it won’t survive the cold winters here. I decided I would need to put it in a larger pot the next spring.
As strange as it may sound, the Agave and may of the other succulents didn’t mind being in the basement over the winter for a few months.
Back outside for the summer once again. I did put it in a bigger pot and remove the offsets. Now they will all have room to grow more.
Sad to say, but I gave up most of my plants in the summer of 2014. Now I am starting over and hopefully someday I will buy another Agave americana.

Just remember that many photos of Agave americana online, even from reliable websites, are actually Agave americana subsp. protoamericana. I also noticed some websites calling Agave americana with the leaves curling downward as Agave americana var. americana.
