I have both the thin leafed Texas variety and the fatter leafed one. The thin leafed one is a pupping fool and will create an area of solid swords in time. I get many flowers coming off my area of lophantha. The other fatter leafed variety is slower to establish, but will start pupping and create a solid area of rosettes in time not the compressed swords. I like the dark green of that variety and it will take parted shade and combines beautifully with my pink lavender thin leafed agave strata "live wires'. I hope I will not have to weed them ever. LOL.

Is this lophantha or iophantha?? No one seems to know!
I recently acquired two small specimens and initially found them a little difficult to ID. They were sold to me as the Shin Dagger (lechuguilla) and though I am in love with that name my iophanthas are a bright forest green with a pronounced lemon yellow mid stripe and the outsides of the leaves are covered in little pale slashes, not the dark ones of the lechuguilla.

These are dangerously thorny little suckers so not child or pet friendly- keep them clear of paths etc. That said, they are mightily attractive with their bold stripyness and evil thorns, and unlike some of my other agaves they seem to have settled in quickly, rooting in nicely and handling the blazing mi... read more

It handled a VERY cold winter in Maryland (2006-2007) without damage. IT was well mulched and in vey well draining soil. But, I am very impressed with it's hardiness. Wouldn't want to fall on it though....

Though this is a pretty striking Agave, it is not one of my favorite, mostly because it suckers into one of the most intensely spiny, dangerous cluster of plants you can imagine. I grew this plant at my previous location and regretted it later on- nearly impossible to remove suckers and the spines can go through your boots. But grown in a pot, it is a wonderful looking species.

Easily confused with Agave lechuguilla.
The differences are:
A. lophantha's leaves are wider in the middle.
Some A. lechuguilla have a stripe in the middle, though faint, but A. lophantha always has the brighter stripe on the average and sometimes faded.
The dried thorns are really close on both but different shape.
A. lophantha dosen't have the dark broken streaks on the outside of the leaf.
