Nolina nelsoni (Blue Nolina)

Native to Mexico, this bold plant has long, 1-inch-wide leaves ranging from grey-green to powder blue. The leaves are edged with tiny teeth. It grows at a moderate rate, eventually developing a tall trunk. Old leaves persist on the trunk and forms a skirt, but may be removed for a neater appearance. Periodically an imposing spike of chartreuse flowers is produced in the summer. Plant in full sun, reflected heat, or part shade.
