This plant has fine deep green linear leaves[2] that are deeply divided with a length of about 40mm.[3] The linear leaf blades occur in crowded alternate spirals are 0.8mm to 2mm in width and taper from the base.[4] This plant blooms with white, lilac or blue pea shaped sweet smelling flowers between October and December.[5] in large clusters toward the end of the branches. Flowering is followed by the production of small pods, each of these contain a single dark brown seed.[6]
