Propagation
Sow fresh seed during spring in pots and place in a cold frame to germinate.
Take stem cuttings of non-flowering shoots during spring and dip cut end into lukewarm water to stop the milky sap from bleeding.
Note:
Contact with the milky sap may cause skin and eye irritation.
Botanic information
Leaf: The sessile lanceolate leaves have a sharp-pointed acuminate apex and a thick fleshy texture. The margins are tinged in bright pink and the leaves are slightly concave from the mid rib.
Flower: The unisexual urceolate flowers have no perianth segments and are arranged in a small cyme that is inclosed in a cup-shaped involucre of yellow petaloid bracts. They appear from late winter to spring.
Fruit: The 3-valve capsule is an explosive schizocarp and contains the numerous seeds. The small seeds are viable but the plant is commonly reproduced vegetatively to maintain true to type.
