So slow growing and not what I thought it was like. I thought it grew into the Artichoke shaped Agave. Instead after 3 or 4 years now,its just as low to the ground as I planted it.
It's almost a plastic plant.

This is certainly a stunning agave, one of the best ornamental succulents IMO.
I have seen quite a few from different sources here in NZ and I've noticed that although at first glance they seem very unlike each other, the colour range can often be attributed more to the thickness of the powdery leaf bloom than actual leaf pigmentation. A very 'bloomy' spec can look chalk white while a medium looks more sky-blue, and another in a very wind-affected position where the bloom has been scoured away can look much greener. Maybe some of the colour differences are in fact environmental instead of genetic- it's just a thought.
Takes hard, hard midsummer sun, and I mean HARD; our UV is off the scale and it doesn't turn a hair when other succul... read more

I am well-acquainted with a Botanist curator of one of the larger private commercial Nurseries/Gardens in the Southwestern US.

This man is respected as an Agave authority and has developed many garden quality cultivars from seed collection expeditions that he has made into Mexico's Mainland Deserts. He has collected seed from the type location of Gentry's Agave titanota, and has these seedlings growing in gardens of which he is curator.

I also have 5 or 6 different clones from these seed collections. All of them have unifying characteristics with titanota, but are quite different in appearance. Some are very grayish blue, others are pea-green, and couple posess a beautiful light sky-blue skin. The leaf-thorn armor is always horn-like, sometimes dark b... read more

Attractive ghostly agave with wide, open crown of few leaves, large lateral spines and pale blue color. Makes a great accent to darker colored plants in the garden.

Kelly Griffin has repeatedly visited and studied the areas of origin for this Agave in Mexico, and is an experienced collector and grower of Agaves. He is pretty certain that this IS the same plant as FO76, as they are growing right near each other, just on opposite sides of a road.. and one side has many forms of this plant that easily blend into the squatter, greener Agave Felipe Otero plants. The bluer forms seem a bit more isolated at the edge of their range, with no green plants around, but some blue plants were found among the green populations. Additionally, seeds collected from blue plants will some... read more
