A long lived plant that is undemanding of soils. Pea like  flowers are carried above glaucous leaves on strong stems. Happy in the same position for a long time as the clump slowly increases in size. Can be propagated by cuttings but is not easy. Seed is a better method if sown fresh and over wintered outside. If the seed is allowed to become very dry the hard coated seeds will need to be chipped as they are almost impermeable to moisture. Expect a little variation in the seedlings.
