Drought Tolerant Plants for the Garden
Drought Tolerant Plants or Water wise plants for the garden are plants that require minimal water once established. Some Nurseries specialise in drought tolerant plants for the home garden and can provide comprehensive lists of drought tolerant plants for specific situations.
Drought Tolerant or Sun Tolerant ?
One of the big issues during hot dry weather are days of high temperature, with 4 or 5 days of temperatures from the mid 30s to mid 40s many gardens will suffer, and drought tolerant plants may not be the answere to these conditions.
For example, Clivia are regarded as drought tolerant as are Hellebores, however they are not able to tolerate hot direct sunlight. Many Australian native ferns are drought tolerant, however if exposed to the heat of the hot sun they may wellnot survive.
Drought Tolerance varies between species in the same genus
Even within a genus, some species will tolerate drier and hotter conditions than others. Campanula are not generally regarded as drought tolerant, however some species are.
Campanula rotundifolia and the Azores Bellflower Campanula vidalii are two that we have grown in full sun and with very little extra water. Other species in the same genus would turn over on a 40 degree day in direct sun.
Choosing the right plants for the right conditions
Although many drought tolerant trees and plants can be obtained through online nurseries, and are generally defined as those that need very little watering once established you will still need to ask a few questions.
- how much water will the plant require
- will it tolerate hot direct sun
- will the soil conditions greatly influence the plants ability to survive in drough
- does the plant recover well. or is it likely to just die
Drought tolerance in plants will depend on the local climate, soil type and positioning. So what plants are drought tolerant ?
In our garden we very rarely water roses, we do keep them well mulched in an attempt to retain moisture and keep the roots cool, but they are exposed to full sun, in our case we regard roses as being drought tolerant. However extreeme hot sun will knock the flowers over very quickly, again drought tolerance and ‘hot sun tolerant’ can be two different things.
We also grow clivia and never water them, so we also regard them as drought tolerant. Try the nurseries listed below for a range of drought tolerant plants.
Drought tolerant Australian Native Plants
Although many Australian native plants are drought tolerant, a large number are not. Drought tolerance will again depend on the species and the conditions.
