Seed pods are 4 to 5 cm long. They become black on ripening, and contain 8 to 12 black seeds. About 35,000 to 40,000 seeds weigh 1 kg. The shrubs have no thorns and produce profuse masses of fragrant white pea-like flowers in early spring, making them attractive ornamental plants. The white flowers distinguish C. palmensis from related, unpalatable species that have yellow flowers.
Cultivars develop that are suited for specific environments.
Seedlings survive with equal vigor in deep coastal sands in the hot and arid climate of Geraldton, Western Australia. Chamaecytisus palmensis establishes most easily on sandy-surfaced soils, but tolerates a wide range of soil types including gravels, loams, acid laterites and limestones. The shrubs tolerate a pH range of 5.0 to 7.0, but require soils that are free draining. Under waterlogged conditions, they are susceptible to root rot and mortality is high. Seedlings are remarkably drought resistant and can survive six months of hot weather without rain or irrigation.
