As climate change presents us with the challenge of gardening with less water, choosing plants to suit our growing conditions becomes paramount.
Top five drought-resistant plants
With some conditioning of the soil and careful watering, there is a considerable range of plants that can tolerate dry conditions once they are established.
Many drought tolerant plants have silver or grey-green leaves, their light leaf colour reflecting the harsh rays of the sun. Some have a coating of fine hairs on their leaves or stems, helping to trap moisture around the plant tissues. Below is a selection of plants with good drought-tolerant properties.
Acacia dealbata (mimosa) AGM: Height 15-30m (50-100ft); spread 15m (50ft)Cercis siliquastrum (Judas tree) AGM: Height and spread 10m (30ft)Koelreuteria paniculata (golden rain tree) AGM: Height and spread 10m (30ft)Ptelea trifoliata ‘Aurea’ (hop tree) AGM: Height: 5m (15ft)
