This diminutive species is a mountain endemic, found in the tepuis and neighboring ranges of Venezuela and its bordering countries. Plants often grow in sandy soils or shallow seeps, or cracks in rock outcroppings where debris and moisture collects, at elevations of 1,000-2,500 meters. They can reach up to 20 cm tall, perhaps more, on a column of old leaves, and form rosettes at the top up to 4 cm across. Leaves are usually semi-erect to prostrate, roughly wedge-shaped with a short, pubescent and broad petiole and obovate lamina ringed by elongate snap tentacles. Coloration ranges from a rich olive green flushed with crimson to solid bright to deep red. Inflorescences may reach more than 20 cm tall (more commonly 10-15), covered in a distinct glandular indumentum, and bear one to several small 1 cm blooms with rounded, white petals. This species is considered a close relative to D. roraimae, from which it differs in its more compact, broader-leaved rosette.
Cultivation: grow in a 1:1 sand/peat mix, kept moist to even wet and humid with temps of 65-85°F during the day, dropping 10°F or more at night. In summer, allow the pot to dry slightly to stimulate blooming. Sow seeds on soil surface, and grow in strong artificial light to full sun.
Lifespan and reproduction: perennial. Reproduces through seed and division, but may be grown through leaf and root cuttings.
