Drosera binata, commonly known as the Fork-leaved sundew[1], is a large, perennial sundew native to Australia and New Zealand. The specific epithet is Latin for "having pairs" - a reference to the leaves, which are dichotomously divided or forked.[1] This species occurs naturally in Australia, primarily in coastal areas from Fraser Island in Queensland, south down through NSW and Victoria to Tasmania and the south-east corner of South Australia. D. binata's range extends to New Zealand where it is common below 1000 metres, being found in both the North and South Islands, Stewart Island and farther afield on the Chathams.[1]D. binata is unique among sundews in having narrow, branching leaves. Some populations go dormant in the winter, while others are truly tropical.

[edit] Cultivation

Drosera binata cultivation is considered to be among the easiest among the genus, similar to that of Drosera capensis. Plants should be grown in a nutrient-free potting mix (such as sphagnum peat moss and washed sand), given high levels of light, and kept constantly watered using distilled, RO, or sterile rain water. Dormancy is not required. Their seeds require a short period of cold stratification in order for germination to occur.
