This hybrid is monocarpic (blooms only once and then dies and does not produce offsets). Each of its rosettes consists of a tight whorl of succulent, rigid, thick, chalky blue-green leaves (to 18” long and 1 1/2” wide) and are almost spineless. The leaves have a very bright red margin edged by an even thinner yellow line and a pointy red terminal tip.
  • Propagation: it does not produce pups off the mother plant and the seeds cannot be relied on to produce true, so it has to be replaced by a new plant when it dies.
  • Wildlife: unknown
  • Facts: 'Blue Glow’ (Agave attenuata x Agave ocahui) was hybridized and was introduced in Rancho Santa Fe, California by Kelly Griffin of Rancho Soledad Nurseries.
  • Designer Considerations: Use in rock or succulent/cactus gardens, as an accent or small specimen plant, it also grows well in containers on a patio or as an indoor plant.
