Form & Character: Upright, arching, clean and shiny.
Growth Habit: Evergreen, herbaceous perennial, clumping with compound leaves extending upwards and arching to 3-feet long with somewhat greater spread, acaulescent with underground succulent rhizomes (stems) containing swollen water-storing tubers.

Light: Shade, prefers indirect sunlight and is tolerant of low light interiorscapes for extended intervals. Intolerant of direct Phoenix sun.
Soil: Tolerant, but in Phoenix ZZ plant grows best in a fast-draining soil or soilless substrate consisting of organic matter and pumice. Fertilize sparingly no more than three times a year or if its foliage begins to fade from its otherwise deep lustrous green color..
Watering: When grown in containers, ZZ plant can survive and even flourish for extended periods of several weeks to months without water. Highly intolerant of overwatering. For indoor culture, use harvested rainwater when ever possible.

Additional comments: ZZ plant is the consumate container plant for shaded, indirect sunlight exposures. Its deeply green, glossy, shiny foliage make it a fabulous foliar accent plant for outdoors in shaded entryways, covered patios or atriums, or it can flourish indoors with minimal care provided there is sufficient indirect sunlight from a large window.
