WILDFLOWER SEED MIXES

Our wildflower seed mixes showcase the unparalleled splendor of Mother Nature’s creations. These meticulously designed mixes contain a diverse array of species, carefully selected to thrive across various landscapes and climates. Each blend contains a wide variety of blossoms that will bloom throughout the season. Many species included in the mixes are perennials, ensuring long-term growth, with some annuals for quick establishment and early blooms. Many of the annuals will reseed, ensuring their presence in your wildflower area year after year.
The Rocky Mountain Wildflower Mix, Great Basin/Colorado Plateau Wildflower Mix and Southwest Desert Wildflower Mix are comprised of only species native to the USA. The Semi-Low Growing Wildflower Mix, Pollinator Wildflower Mix and Drought Resistant Wildflower Mix contain mostly native USA species but also a few introduced species.
Each mix is thoughtfully packaged in a resealable bag, allowing for easy storage of leftover seeds for future planting. For optimal preservation, we recommend storing seeds in a dark, dry, cool place or in a freezer. Additionally, every wildflower zip lock bag is presented in a reusable cloth sack, complete with an attached seed tag which contains a list of species included in the mix and a simple planting guide to ensure successful planting.
