If you have an existing garden bed, or you would like to start one, in a dry and sunny area of your yard, you can still create a garden that is lush and colorful. There are many flowering perennials and shrubs that are drought tolerant and will thrive in dry soils.
Below is a list of 10 drought tolerant plants that you can plant in your garden right now.
1. Spanish Broom
Flowering time: Early spring to early autumn
Spanish Broom, other known as rush broom or weaver’s broom, is a slightly tender, hardy shrub that has become so common on the Sunshine Coast of southwestern British Columbia, some people there regard it as an invasive plant. But this vigorous growing plant adds brilliance and charm to any desert or windswept, seaside garden. And, if given proper care, Spanish Broom will thrive year after year without taking over your garden.
Spanish Broom does well in shallow chalky soil that is fast-draining and in full sun. Once established, it requires only a little watering and a light, annual prune. It grows 7 to 10 feet, making it ideal for large garden beds.
2. Giant Feather Grass
Flowering time: Early to late summer
With its impressive size, this hardy perennial grows to 6 to 8 feet, making it ideal for the following: To be used as a ground cover, a natural focal point in a garden, or even as a hedge. Its erect-stemmed inflorescences are attractive year-long and can be used for indoor decoration.
Giant Feather Grass prefers moderately fertile soil that is well-draining and it can tolerate periods of drought, making it an optimal plant for temperate climates.
To control its size, remove the old foliage in early spring.
3. California Lilac
Flowering time: midsummer to mid-autumn
California Lilac is best used as a border along a wall in a sunny location, or as a hedge. A California lilac, if planted in a sheltered area that receives full sunlight for more than 6 hours a day, will grow up to 12 feet high. Their succession of powder blue flowers emits a soft fragrance which is highly attractive to bees.
California lilacs don’t do well in shallow, chalky soils. They do best in light, well-draining soil so long as young plants are watered regularly throughout their first season. If the soil in your garden is mostly clay, add in horticultural grit and organic matter to a depth of 12 -18 inches deep. This will help improve drainage in your soil.
Flowering time: mid-to late summer
If the desert look is what you’re going for in your garden, or you do live in a desert, then a Yucca will be a perfect fit. This hardy, drought and heat tolerant perennial prefers full sun and fast-draining soil and does best in areas that are protected from strong winds.
5. Feather Grass
Flowering time: midsummer to early autumn
Other known as needle grass or spear grass, this ornamental grass prefers light, well-draining soil in full sun. Its small size makes it a great option for container gardens, or as a border in a garden bed. Its cream-colored plumes add a subtle beauty and sophistication to any garden.
6. Silver Sage (Salvia argentea)
Flowering time: mid-late summer
Silver Sage or Salvia argentea, a hardy biennial, is prized for its gray-blue or silver broad leaves with their wooly texture. It’s categorized as a biennial because it usually dies off once it’s finished flowering. Though, the life of a Silver Sage can be prolonged by pinching off the flowering shoots before they start.
Silver Sage prefers quick-draining soil in direct sunlight. It will also thrive in shallow chalky soils.
This plant adds a sense of calm and serenity to a garden. It can be planted as a border in a garden bed or in a container.
Flowering time: midsummer
Lavender adds an element of peace, calm, and serenity to any garden and its fragrant flowers are quite attractive to bees. Pesky animals, like deer hate lavender because of the acrid sap in its flowers. This is one reason why lavender is a popular choice for gardeners. It can even be used as a small hedge which makes for a gorgeous sight in a garden.
Lavender does best in well-draining soil in full sun, and it prefers hot, dry climates which makes it an ideal desert plant.
Flowering time: early to late summer
Dianthus, other known as carnation, adds beauty, splendor, and an element of romance to any garden. While it doesn’t have a long flowering season, deadheading these plants after their first bloom can promote a second bloom later on in the summer.
This plant can be planted in a container, as a border in a garden bed, or in between paving stones, so long as it is planted in well-draining, alkaline soil in full sun. Dianthus also does well in shallow chalky soils. Although this plant is drought tolerant, it does not like the extreme heat of summer, which makes it a better suited plant for temperate climates.
9. Geranium (Cinereum Group)
Flowering time: late spring to late summer
This hardy member of the geranium family is prized for its long flowering period that can even be extended further with regular deadheading. Geraniums, the cinereum group can be grown in either a garden bed or a container. Most fast-draining soils are suited for cinereum group geraniums and they do best in warm, sunny areas. The warmth and sunshine encourage the production of many flowers throughout the season.
10. Stonecrop Sedum
Flowering time: summer and autumn
Stonecrop Sedums, a type of succulent, are low-maintenance plants that are easy to care for. Their large flower heads and deep-green waxy foliage adds color to your garden in the late summer and autumn months when other flowering shrubs have finished blooming.
These plants will thrive in any soil that is fast draining and they do well in full to part sun. Tall hybrids of Stonecrop Sedums flower their best in full sun, while creeping stonecrop varieties can flower well in either full or part sun.
These 10 plants listed are only a few out of many drought tolerant plants available on the market. While this list is intended to get those ideas flowing about what to plant in your dry, sunny garden, the vast availability of such plants gives you more options to choose from.
Keep in mind that not all drought tolerant plants do well in heat. Also, all plants will need to be watered regularly throughout their first season until their root systems are established enough to find moisture within the soil.
If your garden is located in an area near a window or paved driveway, it will receive more heat than other areas of your yard throughout the summer months. So you will need to choose drought tolerant plants that are also heat tolerant for those areas.
