About Plant Select plants

Plant Select is a non-profit collaboration between Denver Botanic Gardens, Colorado State University and professional horticulturists. We find, test and select plants that are ideal for the high plains and intermountain regions. Then, more than 100 participating growers, botanic gardens and retailers help get the plants to market.

You can find Plant Select plants from independent garden centers, online retailers and wholesalers. Ask for Plant Select on your next visit.

If your retailer doesn’t have the plant you want, let them know you’re interested in it. Demand can help drive what retailers carry. In some cases, they may be able to order the plant for you.
