About

Blue Glow is a cultivar considered to be a hybrid between Agave attenuata and A. ocahui. According to a US grower, it was made by breeder Kelly Griffin while working at a California nursery, and the grower began selling tissue-cultured plants in 2007. It forms a single rosette that slowly reaches about 60 cm tall and 90 cm wide. The blue-green leaves, about 45 cm long and 2.5-4 cm wide, have red margins edged in yellow, tiny soft teeth and a short, stout red tip spine. It resembles neither parent, but seems to take tough, stiff leaves, a small size, a solitary habit and a sharp tip spine from ocahui, and broader leaves and blue-green colour from attenuata. A similar, older hybrid, 'Red Margin', was once confused with it, while the clumping, soft-leaved 'Blue Flame' is entirely different in size and form. A Japanese succulent encyclopedia notes that it closely resembles 'Blue Ember' and 'Burnt Burgundy', with Blue Glow tending to have narrower leaves and smoother edges. In Japan it is widely sold by garden centres and online shops.
