Drosera roraimae

D. roraimae.jpg

Range: Guayana Highlands, Venezuela, Brazil, Guyana

 

This highland Latin American species is a native of the tepuis and plateaus of northern South America, among them Mt. Roraima from whence it gains its name. It grows above 1000 meters in elevation in sandy soils in swamps and depressions, or nearly anywhere else perpetually wet. Plants may develop stems up to 10 cm long, topped by a rosette to 5 cm across composed of semi-erect spathulate leaves. Petioles are parallel and comprise most of the leaf length and distinctly pilose abaxially, tipped by an ovate to obovate lamina often slightly curved in form. Color is light to deep green with blood red tentacles, or even to solid maroon throughout. Inflorescences may be up to 30 cm high, covered in small glandular trichomes, and may bear up to 20 blooms. The flowers are relatively small, rarely reaching more than .75 cm across, composed of obovate to broadly spathulate white or pink petals. This species is readily distinguished from its relatives by the moderately large rosette and lengthy erect, pilose petioles with short lamina.

 

Cultivation: grow in a 2:1 sand/peat soil or a 1:1 long-fiber sphagnum and perlite mix, kept very moist to wet but well oxygenated and humid, with temps of 50-80°F year round, cooler at night if temperatures are high during the day. Sow seeds on soil surface, and grow in strong artificial light to full sun.

 

Lifespan and reproduction: perennial. Reproduces through seeds and occasional branching, and can be grown through leaf or root cuttings.
