Deuterocohnia LONGIPETALA

Deuterocohnia LONGIPETALA - Long-petaled deuterocohnia, Deuterocohnia longipetala.

Deuterocohnia is a small genus of evergreen succulent plants in the family Bromeliaceae. It comprises 18 species of long-lived ornamental plants distributed in South America, namely in Chile, Brazil, Argentina, and Peru in the Atacama Desert, at elevations of 500 to 3,000 m (1,640 to 9,840 ft) above sea level on slopes, crevices, and fractures of hills and rocks. This is an arid mountainous region where the dry season can last up to 10 months and annual precipitation is 100-300 mm (4-12 in). Plants obtain the required moisture primarily from oceanic fog.

The plant produces numerous daughter rosettes and expands rapidly, forming mounds. In nature, colonial clumps of this genus grow up to 2 meters (6.6 ft) in diameter, accumulating dense rosettes averaging 17 cm (6.7 in) in diameter, formed by bluish or green slender leaves that are sharp and sometimes lined with spines along their entire length. It blooms with panicles of sturdy orange tubular flowers. Flower coloration can be green, yellow, orange, or violet.

Outwardly, the plant resembles a small agave or aloe.

Deuterocohnia longipetala is distinguished by long and thick bluish-green leaves. It grows predominantly in the Atacama Desert in Chile.

It propagates easily by seeds, which retain their viability for a prolonged period.

Seeds are sown superficially into a light mixture consisting of leaf mold and sand (1:1), moistened with a spray bottle, covered with film, and germinated in light, but not in direct sun at a temperature of 15-18 °C (59-64 °F). Seedlings require ventilation. It is essential to avoid waterlogging and drying out of the crops.

Seedlings most often emerge on day 5-15. Plants grown from seeds begin to flower in the 4th-5th year.

Deuterocohnia should be grown like other succulents in sun or light shade and in well-drained soil. It grows slowly and is very drought-tolerant. Watering is carried out moderately in spring and summer, allowing the soil to dry between waterings. In the winter period, watering should be restricted.

One should avoid watering the leaves and never pour water into the rosette. The plant obtains the necessary moisture level from the air. During the first 3-4 months, the soil should only be slightly moistened. Despite being one of the hardiest bromeliads, it cannot overwinter outdoors in cold periods because it is completely intolerant of moisture on foliage at cold temperatures.

A temperature of 16 °C (61 °F) is preferred. When grown in pots, it spreads uniformly in all directions and after some time forms a 'mound' of thick spiny leaves in a semicircular dome, completely covering the pot.

The plant can be propagated by leaves or seeds. When propagating by leaves, a healthy leaf is carefully detached from the mother plant, dried for a few days, planted into well-drained soil, and watered as the soil dries out.
