Drosera grantsaui

D. grantsaui  from Brazil

Range: Southern-Central Brazilian Highlands, eastern Paraguay

​

This widespread member of the Drosera montana group can be found nearly throughout the highland plateau that covers most of central and southern Brazil and possibly into neighboring countries (one confirmed record from near the Brazilian border in Paraguay), growing in intermediate to highland elevations from 500-1500 meters, in sandy or peaty soils amongst grasses in permanently moist locations in savanna or grassland habitats. Plants may reach up to 28 cm tall on narrow vertical stems, with a very loose alternating rosette of leaves clustering near the tip (the rest of the stem often draped in old leaves). The leaves may be up to 2.5 cm long, thus the rosette 5 cm across, with half to 2/3 their length composed of a distinctly almost spiky pubescent petiole and the lamina narrow oblong-linear in shape. Coloration overall is typically light green overlain in a heavy red blush, and tentacles crimson; often plants may turn solid red. Inflorescences may reach 27 cm in length, sparsely glandular, and bear 1 cm pink, white or even lilac-shaded flowers with teardrop-shaped (obovate) petals. This species differs from its relatives and neighboring species by its very visible but sparser indumentum (dense in species like D. chrysolepis) and lengthy stem (shorter in D. peruensis or nonexistent in communis) or stem and prominent petioles (D. montana).

 

Cultivation: grow in a 1:1 sand/peat soil, kept very moist and humid, in temperatures of  70-85°F day, 50-65°F night, year round. In summer, permit the soil to dry slightly to signal seasonal changes and trigger blooming. Sow seeds on soil surface, and grow in strong artificial light to full sun.

 

Lifespan and reproduction: perennial. Reproduces through seed, but can be grown through leaf or stem cuttings.
