Proven Winners:

US: Trial results from North to South

Each year Proven Winners releases trial results of their plants as they receive the information from trial gardens around the United States and Canada. They spend a lot of time selecting the plants that perform the best across the continent, using a simple system of rating:
  • Top Performer: Means plants have received at least 4 of 5 points (5 being a perfect score) using the national trial garden scale.
  • Perfect score: Plants that have a perfect rating at a given trial site
  • Trial recognized: Many trial sites have awards and local programs for top performers. These local favorites are top performers in that trial.
The breeder separated the continent into 4 quarters: Northwestern, Northeastern, Southwest and Southeast. This gives you a quick reference for trial results in your part of the country.
