Proven Winners® Perennials

Proven Winners® Perennials

At White Flower Farm, we rigorously test and trial the plants we offer our customers. The Proven Winners® brand does precisely the same thing. Their perennials are put to the test in gardens around the world. Trialed for vigor, resistance to disease and pests, and tolerance of heat and humidity, they wear the Proven Winners® label because they’ve earned it. We’re pleased to offer a variety of Proven Winners® perennials.
