Botanic information
Leaf: The slightly pubescent leaves are 2-3 pinnate with ovate leaflets that have a deeply serrated to dentate margins and the upper surface is mid-green and maybe flushed purple. When crushed the leaves have an apple like aroma.

Flower: The crateriform flowers have 5-obovate notched petals and 5-slender whitish exserted stamens and a deep maroon style.  They are arranged densely in a terminal umbel that is up to 60 mm (2⅜ in) wide and is held high above the foliage on a branched reddish scape that appears from late spring to mid-summer.

Fruit: The dehiscence schizocarpic capsule normally splits into two 1-seeded mericarps with a connecting stalk. The small seeds are viable but the plant may be reproduced vegetatively to maintain true to type.
