Trialed Every Step of the Way

Plants in selection first undergo Landscape Trials where they are evaluated against similar new plant selections and industry standards. Varieties that excel in this category are then moved to Container Trials for further evaluation and on to Production Trials. At each stage we are looking for plants that distinguish themselves against other offerings and will benefit our customers and end consumers.

Goal Oriented Approach

In addition to the expectation of better landscape and production performance, each breeding project is approached with genus specific goals. By honing specific characteristics through multiple generations of breeding, we are able to find new and unique introductions that improve upon market standards.

Over 80 Active Projects

Each year our New Plant Development department works on projects involving more than 80 plant genera. From these projects we will make and evaluate more than 35,000 unique crosses each year. While many seedlings are quickly eliminated at the onset, thousands make their way to landscape trials.

In addition to our internal hybridizing efforts, New Plant Development also evaluates cultivars and species submitted by outside sources for consideration.
