Botanic information
Leaf: The pinnate blue green leaves have obovate to spathulate leaflets that are aromatic. They are arranged alternately along the slender stems.

Flower: The small dull yellow cyathiform (cupped-shaped) flowers are arranged in a cyme that is held away from the foliage on a slender peduncle and appear in early summer.

Fruit: The dry capsule is explosive and produces many small seeds that are viable but the plant may be reproduced vegetatively.
