It is an evergreen perennial plant that has up to 6 leaves per rosette that more closely resemble a succulent or cacti than a garden perennial. Mature leaves are dark green with light gray-green cross-banding, and usually range between 2.5 and 3 feet in length and 2 to 2.8 inches in width. Leaves which develop under bright light out of doors or in bright greenhouses have prominent light cross-bands, while those which develop under 2000 foot-candles or less, or are held under low light intensities, have nearly solid dark green leaves.
