Drosera, commonly known as sundews, comprises one of the largest genera of carnivorous plants, with at least 194 species. These can be found widely spread on every continent except Antarctica. Sundews, (depending on what species) can form either prostrate or upright rosettes, ranging from 1cm to 1m in height, and can live up to 50 years.
Sundews are characterised by movable glandular tentacles, topped with sweet sticky secretions. When an insect lands on the sticky tentacles, the plant is able to move more tentacles in the direction of the insect to trap it further. Once trapped, small sessile glands will digest the insect and absorb the resulting nutrients, which can then be used to aid growth.
