PLANTS FOR HOT, DRY GARDENS

Water efficient or drought resistant plants are the significant plants in areas with low rainfall. They also become sought after plants for general gardens when climatic conditions with lower rainfall prevail. As water becomes scarce and costly, these tough, enduring plants will no doubt become more significant in every garden.

Many of the listed plants are indigenous. All of these plants are suitable for growing in KwaZulu-Natal gardens. Some are cold hardy whilst others require more sub-tropical climatic conditions.
