Propagation
Sow fresh seed during spring in pots or in situ. The seeds germinate readly.

Botanic information
Leaf: The broad ovate to ovate-lanceolate leaves are up to 50mm (2in) wide and have an acute to acuminate apex with a petiole up to 20mm (¾ in) long. The margins are serrulate to entire and the upper surface is bright green and the underside is dull green. The lower leaves are pinnate with up to 3-pairs of leaflets but are not normally seen. 

Flower: The small yellow cyathiform flowers have long slender green sepals up to 9mm (⅜ in) long and 4-spreading obovate petals with exserted stamens. They are arranged in a terminal raceme that becomes elongated after flowering and appear from late spring to early summer and sporadically throughout summer.

Fruit: The cylindrical or flattened silique has valves that are 3-nerved and the tiny seeds are very viable and self-sow readily and under ideal conditions the plant can become a weed.
