About PoaIndex

PoaIndex helps people explore turfgrass species and cultivars with honest, evidence-backed rankings — closer to university extension guidance than to a storefront.

Principles

  • Independent & evidence-backed

    Species suitability and cultivar rankings are always shown separately, grounded in curated NTEP history.

  • Transparent & complete

    Every species returned for a location is listed, even when cultivar evidence is thin.

  • Honest about data gaps

    Insufficient NTEP data is a first-class empty state — never a fabricated ranking.

  • Not a storefront

    PoaIndex surfaces confirmed retail and vegetative directory observations where available; it does not assert live inventory or recommend a purchase.

Data sources

PoaIndex aggregates public sources. It does not invent trial results. Confirmed retail and vegetative supplier observations may appear in results; they are not live inventory claims.
