Best Perennials for Houston (Updated 2025 Guide)

Real Recommendations from Garden Guy the Aggie Horticulturist — Based on 33+ Years Landscaping Houston Homes

If you’ve ever bought a plant that looked amazing at the nursery — but turned brown, wilted, or crispy once Houston’s heat kicked in — you’re not alone.

Gardening in Houston isn’t like gardening in the rest of the country.

Between:

🔥 100°+ heat
💦 high humidity
🧱 heavy clay soil
🧊 unpredictable freezes
🐛 tropical pest pressure

…plants here need to be tough.

The good news?

There are perennials that love Houston, return year after year, and make your yard look great with less work.

After 33 years designing landscapes in Sugar Land, Richmond, Katy, Missouri City, and Greater Houston, here are the plants that consistently perform — not just survive — in our climate.
