An extraordinarily shade, drought, disease, and pest tolerant houseplant, ZZ Plants are slow-growing perennials that grow without stems. They spread by rhizomes after many months and re-root fairly easily.
Zamioculcas zamiifolia (ZZ Plant, Arum Fern, Aroid Palm, Cardboard Palm)
Hardiness Zones: 9-10, keep in 60 degrees Fahrenheit or warmer
Height: 0.6-0.9 meters (2-3 feet) tall
Diameter: 0.6-0.9 meters (2-3 feet) wide
Growth Rate: slow
Root System: rhizomatous
Tolerates: drought (in very low light levels may go without water for a few months), shade (extremely tolerant), no known insect/disease problems (highly tolerant)
Problems (major): wet soils sometimes fatal
Problems (minor): none
Poisonous: toxic to ingest
Soil requirements: prefers somewhat moist, nutrient-rich, medium/loamy soils
Air requirements: prefers humidity above fifty (50) percent
Watering requirement: low, allow soil to dry out between watering
Sun requirement: partial shade to full shade
Leaf shape: pinnately compound, opposite, 6-8 leaves per petiole
Leaf size: to 15 centimeters (6 inches) long
Flower structure: inflorescence with a green spathe, cream-white tiny flowers on spadix
Flowering frequency: uncommon indoors
Subterranean storage organ: rhizome
Monoecious/Dioecious: monoecious (inflorescences have male and female flowers)
The ZZ Plant resembles cycads (specifically the Cardboard Cycad, Zamia furfuracea) more than some aroids, hence some of its common names.
These are becoming increasingly common houseplants due to their many resistances and glossy foliage.
