This plant can get HUGE and trying to dig it up after it has taken root is worse than a chore most people can't do. If stuck by the sharp end it can hurt for days.

Yucca treculeana is hardier than given credit if it's planted in a very (I mean VERY) well draining location. I've seen it planted in zone 6 Southwestern Kansas doing well in sandy dry situations. It can grow quite big and looks stunning in flower. It does have very stiff and sharp leaves which can leave you wounded if you get too close, so make sure you plant it in an area where people won't accidentally brush up against it!

It's not endemic to Texas as posted earlier, but is native over most all of the Southern third of New Mexico and much of the Northern parts of the Mexican states of Zacatecas, Chihuahua, Coahuila, and Tamaulipas as well as the SW 1/2 of Texas, South and West of a line roughly from Galveston, TX to Brownfield, TX.

Very nice looking yucca. I've seen them planted in yards and gardens in Oklahoma and the flowers look neat. And its the biggest yucca that I've seen other than the tree yuccas.

A very hardy drought, heat, wind and infertile alkaline soil resistant plant that is a prolific reproducer in the Lower Rio Grande Valley of Texas around Brownsville, Harlingen, Los Fresnos, Port Isabel, South Padre Island, McAllen,etc. These natives can be found on the sides of roads everywhere here in the dryest of areas along with cactus, mesquite,huisache,etc. Reproducing them is a simple matter of cutting any part of a stem from 6" long to a 5' tall piece and sticking it in the ground or a pot. The stem only needs water when the soil gets completely dry. This is a crucial component of our South Texas native scrub and is used by a host of wildlife. Laguna Atascosa NWR or the Texas Sabal Palm Audubon Sanctuary are places around Brownsville where such Rio Grande natives can be viewed in their natural settings with many bird species and other wildlife, even including an occasional ocelot..

San Antonio, Texas
This yucca has a simple trunk that may have a few stout branches. The leaves are a pleasant bluish-green and they form a large head. The creamy white blooms are followed by many seeded fruit that turn into reddish-brown to black pods. The blooms may be eaten alone, in salads or sauteed with onions and/or nopalitos. The seeds need to be soaked for at least 24 hours before planting.

In the wild, javelinas munch on the trunks and white tailed deer may sometimes browse the leaves as do cattle. Birds make use of the of the plant as a nesting site due the protection offered by its thorns and the good cover it provides.
