Propagation
Sow fresh seeds during late winter to early spring in containers and place a cold frame to germinate.  

Basal cuttings taken during spring.
May be difficult to transplant when large as roots disliked disturbance.

Note:
Contact with the milky sap may cause skin irritation, wear gloves when handling.

Botanic information
Leaf: The variable sessile leaves are lanceolate to elliptical or ovate with a cuneate to obtuse base. The apex is acute and the leaves are arranged oppositely or in whorls of 3-4. The surfaces are densely pubescent and the underside has prominent venation.

Flower: The rotate flowers have a densely pubescent pedestal with 5-sepals and 5-reflexed creamy white ovate petals. The 5-ascending pinkish white hood-shaped lobes extend to the flattened pistil head. They are arranged in an axillary umbel-like cyme that is up to 127 mm (5in) wide and appears above the foliage on a long reddish pubescent scape during summer.

Note
The hermaphrodite flowers are pollinated by bees, insects and butterflies (Lepidoptera). The flowers have 5-stamens and the pistil has a superior ovary.

Fruit: The erect fusiform follicles are normally arranged pairs and contain numerous small flat seeds with tufts of silky hair. The small seeds are viable but the plant may be reproduced vegetatively.
