Answer: The type of wildflower seed mix you choose depends on site conditions and the effect you want to create. Commercial seed mixes may be formulated using a variety of flowers with different heights, colors and bloom times. Usually, a mix of self-seeding annuals, biennials and perennials is most effective. Wildflower mixes also may contain some grass species, which can fill in spaces around flowers, add texture and color contrast, and provide support and protection to wildflowers. Grasses also can reduce soil erosion and enhance wildlife habitat.
I would choose from the following list of wildflowers native to Colorado:
Artemisia, Aquilegia, Columbine, Cleome serrulata, Coreopsis tinctoria, Epilobium angustifolium, Eriogonum umbellatum, Erigeron speciosus, Showy daisy, Eustoma grandiflorum, Prairie gentian, Gaillardia aristata, Ipomopsis aggregata, Scarlet gilia, Liatrus, Linum, Aster, Monarda fistulosa, Oenothera (white evening primrose), Penstemon, Pulsatilla patens, mexican hat, Rudbeckia, Black-Eyed Susan, Thermopsis montana, and Showy goldeneye.
Hope this list gives you some good ideas!
