Oleander (Nerium oldeander)
Reliable summer colour in shades of red, pink, salmon and white. Although these plants are renowned for their poisonous characteristics, their bitter taste is usually an effective deterrent to ingestion.
Silver Cassia (Senna artemisioides)
Native to dry parts of Australia, the bright silver foliage of silver cassia contrasts with its golden-yellow flowers.
Geraldton Wax (Chamelaucium uncinatum)
Geraldton Wax must have perfect drainage and may be short-lived in humid areas.
Japonica (Chaenomeles japonica)
Also known as flowering quince, this great survivor produces a dense mound of thorny branches that sport pretty spring blooms.
Coastal Rosemary (Westringia fruticosa)
Rosemary-like leaves and small, lipped flowers over a long period. Good salt tolerance.
