Flower Mound, TX Landscaping Rules: Native Plants (2026)

Flower Mound's development standards require landscape plans for commercial and multi-family projects to include species adapted to the North Texas climate and Cross Timbers ecology. Recommended species include post oak, bur oak, cedar elm, Texas red oak, Mexican plum, possumhaw holly, Lindheimer muhly, inland sea oats, and sideoats grama. The town's Environmental Services Division promotes native landscaping as a water conservation measure consistent with permanent irrigation restrictions. Residential property owners are free to replace turf grass with native plant beds, xeriscaping, or prairie restoration without a municipal permit. However, plantings must remain below the 12-inch weed ordinance threshold or be demonstrably intentional and maintained to avoid Code Enforcement citations. TX Property Code 202.007(d) protects xeriscaping from HOA bans, though HOAs may require design approval and maintenance standards. The Cross Timbers region supports a distinct assemblage of prairie grasses and savanna woodland species, and Flower Mound's conservation areas preserve native plant communities that serve as reference landscapes for residential gardeners.
