It’s important for you to know that that all plants require water, light, and nutrients to grow. There are however, some plants that need little water or they can survive long periods of time without watering (once established).
These are “drought- tolerant” plants. They reduce the demand for potable water in landscaping, requiring less maintenance and bringing ecological diversity and seasonal interest to the landscape.
Here in Niagara we have become aware of the dangerously low water levels of our surrounding lakes and rivers. We must all become more aware of conserving water. A few simple practices can help the home gardener maintain a beautiful garden while saving precious water, time and effort.
Fine lacy foliage – reduced leaf surface means less water loss
Tick, succulent or waxy leaves – tick leaves store more moisture
Hairy or fuzzy leaves – fine pilosity (fine hairs) keep moisture at the leaf surface
Once planted, they require deep and thorough watering on a consistent basis within the first year to establish the plant’s root systems. Drought tolerant and native plants can only be drought tolerant after the plant’s root systems have developed.
Fertilize drought tolerant plants if they begin to show signs of decline or discoloration.
Most drought tolerant perennials will perform exceptionally for years without being divided. Exceptions include the most vigorous or prolific perennials such as daylilies, hostas and tall bearded irises.
Most common are:
