Deuterocohnia brevifolia ssp. chlorantha is a small terrestrial bromeliad native to Argentina and Bolivia. It is probably one of the cold hardiest of the bromeliads. This small mat or cushion forming plant forms basal rosettes, with individuals reaching from 1.5-2.5 inches (3.8-6.3 cm) across. Individual mats may reach up to 3 feet (0.9 m) across. They are slow growing, forming stout leaves are very stiff with marginal spines. Plants are very drought tolerant and will live in the landscape in USDA zone 9-10.
Blooming: The flowers are very small and insignificant.
Culture: Deuterocohnia brevifolia ssp. chlorantha need full sun to light shade with a well drained soil mix. In the greenhouse, we use a soil mix consisting of 1 part loam to 2 parts coarse sand. Although the plants are very drought tolerant, they do best with average water during the spring and summer. We fertilize the mats only once during the growing season with a balanced fertilizer diluted to 1/2 the strength recommended on the label. During the winter months, water is restricted to once a month and nighttime temperatures are dropped to 48°F (9°C).
Propagation: Deuterocohnia brevifolia ssp. chlorantha is propagated by division and from seed when available.
Deuterocohnia brevifolia ssp. chlorantha was featured as Plant of the Week October 10-16, 2008.
