The Trial Gardens

The Trial Gardens grow and evaluate thousands of plants each year, testing what thrives in the demanding climate of North Texas.

Grown for the Texas climate

North Texas presents real challenges for gardeners. While many catalogs and books describe plant requirements, that guidance is often based on growing conditions in northern states. The climate here is its own.

Winters can be mild, but sharp temperature drops arrive without warning. Summers bring extended heat, periods of drought, and occasional floods. Plants must be resilient to thrive.

The Trial Gardens were established to evaluate how plants actually perform under these conditions, generating practical data for commercial producers, retailers, and home gardeners alike.

Trial Gardens opened to the public

Each year, between 3,000 and 5,000 plants from more than 150 breeding companies are put to the test and evaluated against the full range of conditions North Texas can deliver.

2026 Field Day

Plant Trials Field Day brings together growers, retailers, educators, and garden enthusiasts to review results and recognize standout performers from the trial program. This year’s event features data on plant performance through late 2025 and spring 2026, including which varieties proved best suited to Texas conditions.
