About plant names...

False aloe, actually a member of the agave family, is a North American native.

Identification: Plants are a small rosette of leaves up to 18" (45 cm) tall. Leaves are 5-16" (12-40 cm) long and 2½-3" (6.3-7.6 cm) wide, and curved along their length, with wavy edges. They are soft and thin, but they occupy a place between the thin leaves of herbaceous plants and the thick, water-storing leaves of many succulent plants. Leaves may have varying degrees of brown-purple mottling. Fragrant green or yellow-green flowers appear atop a spike up to 6' (1.8 m) tall.
