Beware sends out runners many feet from original plant so you must constantly dig them up or have your yard totally taken over by them. Also grows fairly fast and becomes so huge it gets incredibly difficult and expensive to remove.

3. mo. ago we purchased 2 blue,3 americana marginata's,2 carribean agave's from a local nursery. they were in 7 gal. containers.we transplanted them into 15 gal. containers and all are doing well.we treat them like cactus and only water them every 3-4 weeks. we are in south florida and they seem to love our sun and heat. they are beautiful and get lots of attention from onlookers. we put them in pots so they wont grow so massive.

I didn't know the true name (Americana) of this plant until this morning, but it is one of my favorite agaves. I have not seen the bloom spike yet, but I believe it also propagates by runners. I am definitely looking forward to multiplying this plant, if and when the time comes.
Bloom spike update: 12-26-06 I had had a 10-12 foot bloom spike on the plant now for a good few months. At first the spike throws out clumps of whispy yellow strands, first blooming at the bottom of the spike and traveling up.
Then the whisps are gone, only to later reveal tender little pups growing on the bloom spike, about an eigth of an inch large now. These are expected to mature a bit on the spike and then I will replant them in chosen spots.
All in all, having this plant in my landscape has been a really positive situation. I am definitely looking fowrd to having more of these plants in my self-propagating south Florida garden.

What was over planted in the 50's and 60's is not so commonly planted anymore. So they now really stand out as front yard plants. And if you remove suckers and worn or laying flat leaves with a pruning saw (makes a easy, clean cut) they actually look elegant with a vase shape. Plus, that helps them to fit in the urban garden.

I have had this plant for three yrs and it has traveled with us. I got this plant in San Antonio as a gift from a lady that had a lot of them in her back yard.
I live in Bossier City ,La and planted it last Nov. almost lost it to frost. I do notice that if it gets to much water it starts to loose the leaves.

As a lover of southwestern plants, cacti and succulents, I
love this and other agaves.
They are not to everyone's taste, but they are strikingly beautiful, and require very little water. Normally, they
only need water obtained from rain, nothing supplemental.
This plant is from the same family of the agaves used to
make tequila.
