Small Tree
The Rocky Mountain maple is much smaller than other maples and prefers to be an understory tree. Rocky Mountain maple or Acer glabrum often turns a brilliant red in autumn. Like other maples it can be picky about alkaline soils, so make sure your site conditions will support it or add iron amendments.
Shrubs
Lots of native shrubs display impressive autumn colors. Three-leaved sumac (Rhus trilobata) and Western sand cherry (Prunus besseyi) both flaunt reds and oranges. Both straight species and cultivars are great low-maintenance plants. Golden Currant can be especially flashy with yellows, oranges and vivid reds. Golden Currant or Ribes aureum is very versatile, doing well in both moderate and low water gardens. Other notable mentions are saskatoon serviceberry and wood’s rose.
Grasses & Perennials
Native grasses are a good choice for any season in the West. Just about any native grass will add fall interest to your garden, however if you’re after autumn colors big bluestem (Andropogon gerardi) and little bluestem (Schizachyrium scoparium) offer hues of red and purple. For more autumn colors in your landscape, sticky geranium displays bright reds that pack a punch. This low growing perennial has delicate pink flowers most of the summer.
Native plants are an essential part of western landscapes. Whether in the wild or around our homes they support a vast array of life. Many people chose to live in Northern Colorado for the abundance of natural beauty and a great way to bring that beauty to your home is planting native plants for fall color. Visit the Conservation Gardens to see examples of these plants and more to inspire your fall landscape.
