HOW TO IDENTIFY A WATER-WISE PLANT

18th December 2017



When planning a water-wise garden, the main objective is to create a space that is both attractive yet thrives with minimal water. You can achieve this by planting mainly indigenous plants, although a few water-wise exotics work, too. Enquire about the specific zones that exotics and indigenous plants can be used in in order to consume water most efficiently, and use our guide to indigenous plants that are also drought-resistant

 

 

Identifying water-wise plants 

We’ve compiled a guide to help you identify water-efficient plants and make an informed decision when planning and creating your water-wise garden. Look for these distinguishable characteristics:

 

Small or needle-like leaves: The smaller the surface area of the leaf, the less water lost through evaporation.  Examples: Ericas, most acacias, rosemary, origanum, thyme

 

Reduced number of leaves/closing leaves: Some plants dispense of their leaves or have leaves that fold closed when water-stressed to reduce the surface area exposed to direct sunlight. This is especially seen during periods of drought.

Examples: Karee, acacias, buffalo thorn

 

Grey foliage: The colour grey reflects the sun’s rays away from the plant to keep it cooler, which then reduces water loss through the leaves.  Examples: Lavender, artemesias, arctotis, giant honey flower (Melianthus major)

 

Hairy leaves: Hairs on leaves slow down air movement past the stomata, therefore reducing water loss. Examples: Silver tree (Leucadendron argenteum), lamb’s ear, beach salvia (Salviaa Africana-lutea), Helichrysum

 

Succulents with fleshy leaves: Water is stored in these fleshy leaves to be used by the plant when required. Examples: Crassulas, aloes, echeverias, vygies

 

Waxy leaves: A waxy characteristic prevents moisture loss. Examples: Euonymus, kalanchoe, Indian hawthorn

 

Lighter underside of leaves: When water-stressed, the lighter underside of the leaves turn upwards to reflect the sun.  Examples: Wild olive tree, gazanias, indigenous buddleja

 

Sturdy internal structure: Some plants have a firm support that prevents wilting during dry spells and drought conditions. Examples: Strelitzia, restios, agaves, New Zealand flax

 

Oils in stomata: Usually in areas with a hot, dry summer, plants have adapted to the weather by secreting oil to coat the leaves and protect against water loss. Examples: Rosemary, lavender, sage
