Drosera oblanceolata

D. oblanceolata Sunset Peak.jpg

Range: Southeastern China and Hong Kong


This is a beautiful but still somewhat uncommon plant in cultivation, often confused with Drosera spatulata and putative hybrids. In the wild this species is recorded from Guangxi Province around Yaoshan down to the coast around Yangjiang and Hong Kong. It may grow from almost sea level to several hundred meters in elevation, in habitats ranging from moist bogs and seepages amongst grasses and cracks in rocky outcroppings to seasonally moist montane faces and karst (where they may rely more on morning fogs and mist than rain or seeps for water). Plants may grow to almost 10 cm in diameter, ranging from smaller flattened basal rosettes to large semi-erect growth (often seasonally). Petioles are parallel and glabrous or with hairs abaxially, may compose half to 2/3 the length of the leaf, while lamina are oblanceolate to almost linear-ovular and up to 3.2 cm in length, often curling inward on large erect leaves. Coloration is brilliant green with red-tinted tentacles to solid crimson in good light. Inflorescences may be up to 12 cm tall and almost entirely glabrous, bearing up to 10 individual flowers on moderately long pedicels. Sepals are distinctly large and almost rounded, flowers themselves are up to 1.5 cm in diameter with very round, glossy pale pink to not quite white petals. This species is quite similar to D. spatulata and ultramafica, but can be told apart from the former by the typically far longer and (in summer larger growth) erect petioles and glabrous inflorescences with very round petals, and the latter in lacking red stipules and lengthier petioles with a more tapered lamina shape.


Cultivation: grow in a 1:1 peat/perlite or similar mix, kept very moist and humid, with seasonally varying temps of 50-85°F throughout the year (often does better in slightly cooler, but not cold, conditions than standard tropical). Sow seeds on soil surface, and grow in strong artificial light to full sun.


Lifespan and reproduction: perennial. Reproduces through seed, and can be grown through leaf, flower, or root cuttings and division.

I have found this to be a fairly easy species to grow, but not always keep in its best possible condition. Plants tend to like fairly open or sandy soil mixes and don't like it when the soil gets too mucky, crusty, or when temperatures in the environment get particularly hot. They don't necessarily want to be in a highland habitat, but do well on the lowest shelves of my main greenhouse alongside such plants as D. linearisD. ultramafica, or D. kaieteurensis. Flexible, but with an intermediate preference.
