Plant Select®, the country’s leading source of plants selected to thrive in High Plains and Intermountain regions, is pleased to announce the 2016 top performing plants as reported by our Demonstration Garden Partners.
Fifty-three public gardens in Colorado, Wyoming, Utah, Idaho, and Montana participated in the Plant Select Demonstration Garden Partner performance surveys in 2016. These gardens display Plant Select winning plants, providing communities with educational opportunities to discover the plants that grow best in their local environments. To qualify as a partner, each garden must:
- display good garden design with regular garden maintenance;
- have a well-planned educational program;
- provide clear and legible signage with proper plant names;
- be open to the public year around;
- and, be at least one year old before applying.
Plants were evaluated on winter hardiness, bloom and foliage quality, and overall appearance and performance on a scale of 1-9. The results are as follows.
Grand Winner: top performer overall
This year’s overall winner is Blonde Ambition blue grama grass (Bouteloua gracilis ‘Blonde Ambition’ PP22,048). Introduced in 2011, this ornamental selection of native blue grama grass was developed by David Salman, founder of High Country Gardens, and owner of Waterwise Gardening, LLC. It received an overall score of 8.3 and was evaluated in 82 percent of the gardens reporting. This is the second year in a row for Blonde Ambition as grand winner.
