Deuterocohnia brevifolia (Griseb.) M. A. Spencer & L. B. Sm.
Abromeitiella brevifolia, Abromeitiella chlorantha, Navia brevifolia, Tillandsia chlorantha
Deuterocohnia brevifolia, also known as Abromeitiella brevifolia, is a terrestrial bromeliad with small rosettes of fleshy triangular leaves with toothed margins and a sharp tip. It grows up to 6 feet (1.8 m) in diameter, forming large compact rounded mats of hundreds of rosettes. The rosettes grow up to 2 inches (5 cm) in diameter. Leaves are up to 1.2 inches (3 cm) long. Flowers are small, cylindrical, intensely green, and grow in the middle of the rosettes on short inflorescences from winter to early spring.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Deuterocohnia is a perennial Bromeliad that forms an interesting mounding ground cover. It grows by slowly dividing into a tight cushion-shaped colony. In its native environments, it is watered perhaps only twice a year, obtaining most of its moisture from the air itself. It can get extra moisture from ocean fogs that roll in.
This is an excellent plant for a small-scale groundcover in rock or succulent gardens. Deuterocohnia makes an interesting specimen plant in containers.
Grow your Deuterocohnia in well-drained humus-rich soil with added pebbles, perlite, hardwood bark, or other material to facilitate drainage. Keep in bright light or part sun and water moderately in spring and summer, letting the soil dry between waterings. Limit water during winter. It is probably one of the Bromeliads' cold hardiest, but detesting winter wet on its foliage proves difficult to keep outside.
