Agave guiengola - This succulent forms open rosettes to 3-4 feet tall by 4 to 6 feet wide. The few massively thick, white-green glaucous leaves are very broad at the base and taper to a brown terminal spine. Along the edge of the 18-24+ inch long leaves there are many dark-colored teeth. When mature this plant produces a 5 to 6 foot tall spike with pale yellow flowers; although we have large plants that are 12 years old in the garden, we have not seen this plant flower. Plant in full sun to light shade and irrigate only occasionally in coastal gardens (seems to suffer from edema from over watering) to regularly in hotter inland gardens. Protect from temperatures below 25 degrees F. to avoiAgave guiengola (Guiengola Agave) - This large succulent forms open rosettes to 4-5 feet tall by 4 to 6 feet wide. The few massively thick white-green glaucous leaves are very broad at the base and taper to a brown terminal spine. Along the edge of the 24 to 36 inch long leaves there are many tiny dark-colored blunt teeth. When mature this plant produces a 8 to 10 foot tall unbranched spike with pale yellow flowers. Plant in full sun to light shade and irrigate only occasionally in coastal gardens (seems to suffer from edema from over watering) to regularly in hotter inland gardens where some shade is recommended. Protect from temperatures below 25 degrees F to avoid disfiguring the foliage. A stunning plant for large containers or planted in a protected spot in the succulent garden. Typically described as being smaller but our main stock plant was 6 feet across when it flowered in 2011 after 15 years in the ground. After flowering 3 pups resprouted that 5 years were each 3 to 4 feet across. Plants in other gardens in Santa Barbara have reached similar proportions. Agave guiengola grows natively on limestone slopes from 330 to 3,280 feet in elevation. The specific epithet is in reference to the Cerro Guiengola, the mountain where the species was first discovered.
The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have observed it in. We also will incorporate comments received from others and always appreciate getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that might aid others in growing Agave guiengola.
