Programs

2010 selections announced by Plant Select, Colorado State University

April 1, 2010

Plant Select, a collaborative effort of Colorado State University, Denver Botanic Gardens, and regional and national horticultural professionals, has announced seven new plants for 2010.

If you are looking for an outstanding xeric shrub that will provide year-round interest and require very little effort, look no further. Redleaf Rose (Rosa glauca) is an exceptionally hardy blooming shrub.

Annual program

Plant Select’s goal is to seek and distribute the best plants for landscapes in the High Plains and Intermountain regions.

To be included in the program, selected plants should have these attributes:

  • Thrive in a broad range of garden situations
  • Be resilient to the region’s challenging climate
  • Demonstrate disease and insect resistance
  • Flourish in low-water conditions
  • Be noninvasive
  • Display a long season of beauty in the garden
  • Exemplify the unique
