Agave americana 'Joanna' (Yellow-banded Century Plant) - This large succulent is slightly smaller than the species but still grows to an impressive 5 to 6 feet tall and 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 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. 

This information about Agave americana 'Joanna' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
