Agave americana 'Joanna' (Yellow-banded Century Plant) - This large succulent is slightly smaller than the typical species, but still grows to an impressive 5 to 6 feet tall by 6 to 8 feet wide. It has long gray glaucous leaves with a central broad band of yellow lines. As with the species, there are recurved spines on the margins and a long terminal spine. Yellow-green flowers attract hummingbirds, however the Century Plant doesn't bloom until it is a decade or so old (not a century!) and the main flowering plant dies after flowering.
Plant in full sun. Irrigate occasionally to not at all. Cold hardy to 15 degrees F.
This plant was a selected mutation of Agave americana var. striata that was noticed by San Marcos Growers supervisor Arturo Garcia and it is named for his daughter.
