Botanic information
Leaf: The 2-ternate basal pinnate leaves are up to 200 mm (7¾ in) wide with a long petiole and are finely dissected with a numerous linear-oblong segments that have an obtuse apex. The upper surface is mid-green and the underside is glaucous.

Flower: The bisexual campanulate flowers have a flattened corolla with 2-green persistent broadly ovate sepals and 4-petals up to 12mm (½ in) wide. The outer two petals are spreading and pouched at the base and the oblanceolate inner two are attached at the tips. 

The flower colour is rose-pink appearing from late spring to early summer. A few flowers are arranged in a short nodding raceme above the foliage on a slender scape to 150mm (6in) long and appear during early summer.

Fruit: The narrow oblong capsule is dehiscent from the apex and contains several oblong smoothed glossy black seeds up to 2 mm long. The small seeds are viable but the plant is commonly reproduced vegetatively.
