The continual rise of global warming has undoubtedly contributed to the incidence of drought, especially in regions already prone to drought.
Considering that Colorado has a dry climate, it is important to know about drought tolerant plants in Colorado as this will make gardening less difficult in this region.
According to the Colorado Climate Centre records, drought has often been described as a frequent occurrence in Colorado.
Historically, Colorado is said to have experienced several years of severe drought. Today, climate change has only worsened this hazard.
A shortage of water often characterizes drought, and it is no secret that water shortage influences the growth of plants.
Hence, in regions like Colorado experiencing drought, it is important to cultivate drought tolerant plants.
Due to the rise of drought and its attendant effect in the state, the Colorado Drought Mitigation and Response Plan was set in place to provide an effective and systematic method for the state to lessen the impacts of water shortages over the short or long term.
Cultivating drought tolerant plants falls under the managing landscape irrigation aspect of water conservation planning, which is part of the goal of the Colorado Drought Mitigation and Response Plan.
Drought tolerant plants are plants that tend to need less water. It is worth noting that these plants require water, although substantially less than many other choices.
With plants like this in your yard, you conserve water while maintaining beautiful scenery. Read on as we examine drought tolerant plants in Colorado.
Drought Tolerant Plants in Colorado

The grass has a fine texture and an attractive uniform appearance, with slightly curly blades.
Buffalo grass grows 8-10 inches and has fine hairs on upper and lower surfaces. The hairs on the blades are not obvious.
They are actually an adaptation technique that helps decrease air movement across the surface of the leaves, lowering the potential for water loss.
This drought tolerant plant can be mowed or even left naturally. When mowed, it gives the landscape a manicured look, and when left to grow naturally, it reduces the maintenance needs while giving your landscape a natural prairie look.
In this untamed state, the grass flowers and produces seeds, attracting wildlife such as birds and butterflies.
It can survive extreme environmental conditions and tolerates sunlight well. Buffalo grass survives cold winter temperatures through dormancy.
The lavender flower, which goes by the botanical moniker Lavandula, is one of the world’s most aromatic and ancient flowers. It is also among the drought tolerant plants in Colorado.
Because of its Mediterranean origin, the hardy variety of lavender will survive the drought in Colorado.
The species of lavender that will strive well here are the English Lavender and Lavandins.

The plant has silver-gray leaves that are soft and feathery, with a pleasant fragrance. It also produces inconspicuous yellow flowers.
Fringed sage will strive under well-drained soil in full sun and become drought tolerant once established.
This plant is useful for landscaping and is excellent as a groundcover or garden accent.
5. Aromatic Aster
Aromatic aster is a perennial wildflower native to North Eastern and Central United States.
It goes by the scientific name– Symphyotrichum oblongifolium, and it can also survive drought in California.

This hardy plant grows in full sun to part day and tolerates poor soils. Aromatic aster flowers make a great choice for year-round color in the garden since the plant tolerates frost too.
6. Apache Sunset
Also among the drought tolerant plants in Colorado is Apache Sunset.
The plant is native to North America, China, and Japan, where they grow in poor, dry ground, which makes it adapt perfectly to the drought of Colorado.

They do well in full sunlight and can grow in a wide range of soil, even on sandy or rocky soil.
African daisy is susceptible to root rot, hence allowing the soil to dry between watering. Once established, they are drought tolerant. It is also resistant to heat and slight frost.
Another drought tolerant plant to be examined in this article is yarrow.
Also called Achillea millefolium scientifically, yarrow is indigenous to the temperate zones of the Northern Hemisphere in Europe, Asia, and North America.
The yarrow plant can grow 2 to 3 ft” tall and 2 to 3 ft” wide, depending on the cultivar.
