Agave ferox "Green Goblet"

Purchased an agave for the gardens this past Sunday at the Hardy Plant Society of Oregon plant sale. Agave ferox "Green Goblet", the meanest looking plant I have never seen. I thought the opuntias were Devil plants with their needles. This beautiful dark rich green plant which is about 9" wide by 7" has a single black spine on the end of each leaf that is about one inch long and there are these little spines that are on the sides of the leaves. Looks like an accident waiting to happen if it is not handled right. Trust me on that statement!

Native to eastern Mexico and reaches about 4' in height x 5' wide.

Drought tolerant and USDA hardiness zone 7b to zone 10.
