Sundews, can form either prostrate or upright rosettes, ranging from 1cm to 1m in height, and can live up to 50 years. They are characterized 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.
