Agave 'Blue Glow' - A beautiful smaller Agave with solitary rosettes slowly growing to 2 feet tall and 3 feet across with 18 inch long by 1-1 1/2 inch wide blue-green leaves that have red margins edged with yellow and bearing tiny soft spines and a stout short red terminal spine. Plant in full to part sun. Little irrigation required. Though hardiness is not known absolutely, it has been grown by enough people that we can say that it should tolerate temperatures down to at least 20° F and we suspect the plant should be much hardier. There are reports of it surviving nighttime temperatures of 17° F at the Juniper Level Botanic Gardens at Plant Delights Nursery in November 2008 (but not the 9°F temperature he had later that winter) and others have told us it has gone undamaged at 15° F in Bishop, California and 21° F in Atascadero, California. Great in containers or in groups - especially nice where back lighting can light up the red and yellow margin. This hybrid between Agave attenuata and A. ocahui is reported to be a Kelly Griffin hybrid. It is a beautiful plant that looks nothing like either parent though it apparently inherits the more durable tougher leaves, smaller size, solitary habit and sharp terminal spine of Agave ocahui and gets the broader leaves and blue green color from Agave attenuata. We have seen this plant described as similar to Agave 'Blue Flame' - while both are in the genus Agave and both have blue-green colored leaves, this is where the similarities end as Agave 'Blue Glow' is a much smaller, solitary plant with stiff leaves and really looks nothing like the large clump-forming soft-leafed Agave 'Blue Flame'. We received our original plant of 'Blue Glow' from the Huntington Botanic Garden in 2005.
This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Agave 'Blue Glow'.
