Agave 'Kazo Bana' is one of the best of the gold-edged forms of Agave victoriae-reginae. Kazo Bana, which means "flower of Kazo", was named by Japanese variegated plant guru, Yoshimichi Hirose. Our 3-year-old plants are now 3" tall x 5" wide, but we expect them to mature at 10" tall x 18" wide with age...great age. The tight, slowly offsetting clumps are composed of thick, dark green leaves highlighted by a butterscotch-gold border and topped with attractive white markings. Although most Agave victoriae-reginae are hardy to Zone 7b, I'd recommend growing this to a larger size before trying it outdoors north of warm Zone 8. Agave flowers attract hummingbirds.
