Central Phoenix -- I have a 20 year old Agave ocahui that is now about to bloom. The flower stalk is 10+ feet tall and growing but not yet with flowers. It is a solitary (non-pupping) plant in the ground against an east-facing block wall. This species really seems to benefit from heat. For the first 10 years of its life, the wall was a cedar fence and the ocahui grew slowly and didn't exceed 3 feet diameter. Once the cedar was replaced with a block wall, the ocahui grew rapidly to 6 feet diameter.
Note as of Dec. 31, 2015 -- Unlike some Agaves that live for a year or more after flowering, my A. ocahui died rapidly after flowering. It flowered in spring 2015 and was completely dead by October.

This medium-sized century plant forms an 18" tall x 3' wide solitary rosette of dark green leaves, edged with smooth reddish-brown margins. When the clumps mature, they are topped with a 9' tall narrow spike of bright yellow flowers.

Hailing from the northern Mexico state of Sonora, A. ocahui can be found on volcanic limestone up to 4,500' elevation.

I have not grown this plant. It rarely suckers. It is suitable for growing in containers due to its small size and symmetrical upright growth.
