Texans planning wildflowers for spring 2027 should plant seeds in fall 2026 to give them time to establish before winter dormancy, according to guidance published by AgriLife Today. The general planting window runs from September through early November, with earlier planting recommended farther north in the state.

Michael Arnold, Ph.D., director of The Gardens at Texas A&M University and professor of landscape horticulture in the Texas A&M College of Agriculture and Life Sciences Department of Horticultural Sciences, said gardeners should expect a wait rather than immediate results.

Choose a site and prepare the soil

Arnold recommends a location with well-draining soil and at least eight hours of sunlight daily. Garden edges and naturalized areas are options for incorporating wildflowers into a landscape. Because wildflowers peak from late winter through midsummer, gardeners should consider where they want seasonal color.

For existing beds, loosen the soil before planting. For new planting areas, clear and till the ground. Spread seeds evenly over the prepared surface, then gently press them into the soil. The seeds need good contact with the soil but should not be buried entirely.

Water newly planted seeds and keep the soil moist without overwatering. Arnold said supplemental watering may be needed when rainfall is insufficient, particularly as seeds begin to sprout.

Mix species with different bloom times

To spread flowering across spring and midsummer, Arnold suggests choosing species that bloom at different times and using a seed blend suited to the gardener’s region of Texas. Regional mixes can be purchased online or from local nurseries that specialize in them.

A mix of annuals and perennials can also provide flowers across multiple growing seasons. Annuals live for one growing season and can flower in their first year. Perennials return for multiple years, but may bloom better in their second or third year.

Arnold’s suggested flowering sequence includes:

  • Early spring: bluebonnets, tickseed and Indian paintbrushes.
  • Late spring through midsummer: evening primrose, Mexican hat and coreopsis.
  • Later summer color: hardy sunflowers.

AgriLife Today reports that most Texas wildflowers need minimal care once established. Arnold recommends allowing flowers to produce seeds before mowing. Cutting them too early can prevent those seeds from replenishing the supply available for the following year.
