Texas Flower Gardens: 5 Plants that Flourish in DFW

Although North Texas experiences a range of temperatures throughout the year, locals should consider hot, dry summers along with unexpected winter and spring freezing temperatures when choosing perennials and annuals.

Planting Texas flower gardens does require some planning. Those looking to add pops of vibrant color and aromatic plants to their yards and patios will want to consider the year-round climate in Dallas-Fort Worth. Although North Texas experiences a range of temperatures throughout the year, DFW homeowners should consider hot, dry summers along with occasional spring and winter freezing temperatures when choosing perennials and annuals.

Louisiana Iris

This hardy perennial is a variety of Iris that is native to the Mississippi Valley. According to the Agricultural Center at Louisiana State University, this plant is resistant to the insect and pest issues that afflict many plants. While the Louisiana Iris does well in boggy conditions, it has proven to be quite tolerant of North Texas weather. This plant can withstand the cold freezes that occur throughout winter and tends to grow well with abundant sunshine — at least six hours of full sun per day.

Purple Coneflower

Another common perennial that works well with Texas soil and weather conditions is the purple coneflower. Also known as echinacea, this flower falls between zones 3–9 of the USDA hardiness scale. According to the Old Farmer’s Almanac, coneflowers are tolerant to drought and make for great cut flowers.


A member of the mint family, perilla is a purple-hued herb that tends to be used as an accent to flowering plants. The Washington Post explains that perilla was favored during the Victorian era as an accompaniment to begonias and pansies because of the color of its foliage. Perilla is edible as a garnish and can accompany Asian cuisine. Also called the Beefsteak-plant, Texas A&M University describes it as aromatic annual that blooms with white and purple flowers but can be toxic to livestock.

Obedient Plant/False Dragonhead

A great plant for fall color, the so-called obedient plant produces pink and lavender blooms during the late summer months and throughout the fall season. Texas Gardener recommends this plant for all Texas zones but mentions that this plant can take over flower beds if not controlled with moderate watering or vertical underground barriers to its root system.


These flowers mimic the appearance of daisies, with golden petals and black or purple centers. Rudbeckia is a perennial that grows well in dry soil and abundant sun exposure. According to the National Gardening Association, rudbeckia looks best when planted in large quantities to border a garden or emulate the appearance of a wildflower meadow. Rudbeckia, depending on the variety, grows two to six feet in height.

For Texas flower gardens, these five plants offer a range of color and variety that can tolerate temperature fluctuations, dry soil, and plenty of sunlight. Of course, this list is only a starting point. Your local nursery can help you design a garden that suits your tastes while also offering additional plant recommendations that can stand up to the Texas sun and summer heat.
