Description: Agave cv. Blue Glow is a great-looking solitary dwarf agave, supposed to be a cross between Agave attenuataSN|277]]SN|277]] and Agave ocahui created by Kelly Griffin. It forms rosettes of smooth spineless foliage with red-tinged margins and a distinctly blue cast save an unimpressive dark terminal spine. "Blue Glow" grows to only 60 cm high and 90 cm wide, but note that it is a relatively slow grower.
Leaves: up to 40 cm long and 2,5-3,5 cm wide, very fleshy, deep blue green rimmed with red margins and yellow edges and bearing tiny soft spines and a stout short sharp, dark-red terminal spine.
Blooming season: Even though agaves are called "Century Plants," they actually bloom about every 10 years or so. Agaves are monocarpic, which means they die after blooming.

The gallery now contains thousands of pictures, however it is possible to do even more. We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present. Read More...
Cultivation and Propagation: “Blue Glow” Agave is suitable for pots because it tends to stay compact and not elongate, as others kinds of agave do. It grows well in a stock cactus mix; light feed in late spring makes for robust plants. It needs some protection from the blasting summer sun if the deep blue-green colour is to be preserved. Both filtered shade for the entire day or or full sun for half of the day works well.
This plant is surprisingly cold hardy and can survive with only minimal leaf damage after clear nights of -10 degrees Celsius especially if under the snow.
Propagation: Micro propagation (Tissue culture). This cultivars seldom offsets unless you destroy the meristem.
