Propagation
Sow fresh seeds during spring and maintain a temperature of 10º to 13º C. (50º to 55º F). Place seeds in a tray of moist potting mix and they may be slow to germinate.

Take cuttings during late spring.

Divide established clumps (rhizome) during spring.

Botanic information
Leaf: The yellowish-green bilobed leaves are held erect on winged petiole and the springed lobes have 15 to 20 spines along the margin. In the centre of the lobes are 3 or 4 sensitive hairs that trigger the closing of the lobes by insects that are attracted to the secreted nectar.

Flower: The rotate flower has green sepals and 5-white petals that widen from the base. There are 3 to 10 flowers arranged in a cyme on a long flat semi-decumbent to erect scape that is up to 160mm (6¼in). They appear during early summer. 

Fruit: The small capsule contains many tiny black seeds. The small seeds are viable but the plant may be reproduced vegetatively.

Note
Leaves
The two lobes are attached to a ridge mid-rib and the inward facing spines interlock with each other when the trap is closed. 

The upper surface of the leaves are covered in two types of glands, one to produce nectar that attracts the insect the other secrets digestive enzymes to consume the prey. After the leaf has trapped 2 to 3 insects it normally dies or becomes inactive. 

If the trap is closed with no insect it will slowly re-open over a 24-hour period but if it has prey the leaf begins the narrowing phase. In this phase the two lobes come together tightly and seal the insect between them, then digest the prey and absorb the nutrients.
