Agave potatorum 'Cubic'
Light: Morning sun with afternoon shade is best in Phoenix. Acclimate gradually to stronger sun; intense summer afternoon exposure can scorch leaves.
Water: Low water needs. Water deeply, then let the soil dry completely; provide occasional supplemental water during hot, dry weather. Water very sparingly in winter and avoid wetting the crown.
Soil: Excellent drainage is essential. Use a gritty cactus mix in containers; plant in raised or sloped beds where native soil drains poorly.
Mature size: Typically about 1–2 feet tall and wide; ultimate size varies with growing conditions and the plant sold under this name.
Bloom: Flowers once at maturity, usually after many years. A reliable flowering age is not established for this cultivar; the flowering rosette dies afterward.
Evergreen / deciduous: Evergreen.
Growth rate: Slow.
