Propagation
Stratified seeds for the three months at 7.2ºC (45°F) and then slow 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 densely tomentose leathery textured sessile leaves are elliptical to ovate. The apex is abruptly acute and the base can clasps the stem or have a short petiole. The pale green mid-rib and pinnate veins are prominent on the upper surface and the margins tend to undulate.

Flower: The rotate flowers have a stout densely white pubescent pedestal with 5-small sepals and 5-reflexed rose-purple ovate petals. The 5-ascending pinkish-white pointed hood-shaped lobes extend past the pistil head. The flowers are arranged in an axillary umbel-like cyme that is up to 80 mm (3⅛ in) wide and appear above the foliage on a long pale green pubescent scape during early 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 semi-pendant narrow-ovoid follicles are densely pubescent and contain numerous small flat seeds with tufts of silky hair. The small seeds are viable but the plant may be reproduced vegetatively.
