Ask Mr. Smarty Plants

You are describing a Meadow Garden, and we have How-To Articles for projects like this. Read first this one A Guide to Native Plant Gardening. Next up, Caring for your New Native Plants. We always recommend plants native not only to North America but to the area in which they are being grown. This makes things much easier, as you don't have to figure out what plant will grow in your soils, survive in your climate or tolerate your rainfall. The plants native to your area will have already learned all those things by centuries of experience.

Before we begin on the project, you might be interested in this  previous Mr. Smarty Plants answer on Colorado Wildflowers, also from Colorado Springs.

Now, go to our How-To Article on Meadow Gardening. After you have absorbed that, we will lead you into our Native Plant Database where, using the Combination Search, enter Colorado, herbs (herbaceous blooming plants, including wildflowers) for Habit,  amount of sunlight available in each part of your yard, and whether the soil is moist or dry. You can change these characteristics as you work until you have just the right plants. We are going to give you a trial list. Because you are in high altitude country, pretty dry ordinarily and definitely with a variety of soils, we are going to check each plant we recommend by accessing the USDA Plant Profile on that plant to discover if that plant is native in or close to to El Paso County, in central Colorado.

From that list, you can follow each plant link to our webpage on that plant, where you can learn time and color of bloom, propagation instructions, preferred growing conditions, etc.
