This spectacular monocot has very intriguing growth patterns and grows to considerable heights in tropical regions. The foliage contains a surprising amount of water (up to one quart of water per leaf blade) that can be used to survive harsh droughts.

Tolerates: drought (once estbalished and mature)
Problems (major): intolerant of cold temperatures (40 degrees F and below)
Problems (minor): Strong winds for taller specimens, leaf spots, difficult to transplant
Poisonous: The entire plant is mildly toxic.
Soil requirements: prefers deep, nutrient-rich, fairly moist, loamy, acidic, well-drained soils – tolerates sand and clay
Air requirements: Prefers temperatures above 60 degrees Fahrenheit, 40 degrees Fahrenheit and below are fatal.
Watering requirement: moderate

Leaf shape: deep-green, banana-like, thick, somewhat succulent, long with slits perpendicular to the long primary “veins”
Leaf size: Leaf blades (laminae) to 3 meters (10 feet) long by 1 meter wide, clusters up to 30 per single trunk, petioles may grow as long as the blades.
Stem: up to 30 centimeters (12 inches) in diameter, grows up to 12 meters (40 feet) tall, initially subterranean on younger plants
Flowering structure: White, 3 petals per flower, occur in cymes, present in boat-shaped, cream-white to light-green colored spathes (similar to Strelitzia/Bird of Paradise plants), has 5-15 sturdy bracts per inflorescence, 10-16 flowers per inflorescence, the entire inflorescence can grow 30 centimeters (12 inches) long, pollinated primarily by lemurs.
Flowering frequency: frequent in summer on mature plants, occasionally during other times of the year
Fruits: small seeds are edible, initially capsule-bound (the capsules grow up to 9 centimeters (3.5 inches) in diameter), and enclosed by blue-arils,
The entire tree, namely the foliage, contains a very considerable amount of water. Can be vegetatively reproduced by divisions and rhizomes.
