Wildflower Seed Mixtures

WILDFLOWER SEED MIXTURES

Mother Nature’s Best

When it comes to spectacular beauty Mother Nature is hard to beat and a diverse array of fabulous wildflowers is truly one of Mother Nature’s best sites.

Stevenson Intermountain Seed, Inc. offers a fantastic selection of wildflower species of seed. Our selection includes a number of species that are hand harvested from wildlands in various areas of the Western U. S. Other species are produced in cultivated fields.

Our selection of standard wildflower mixtures contains many of the best wildflowers that Mother Nature has to offer. Many of our species are not found in other company’s wildflower mixtures because of their higher costs and low availability. Many are species that are more specifically native to the Intermountain Region of the U. S. We are pleased that we are able to offer our exclusive premium wildflower mixes at a very reasonable cost.

We offer seven standard wildflower seed mixtures for use in the Western United States. Each mix contains a large number of species that have been selected to provide a broad range of geographic and environmental site adaptability while creating a spectacular display of many colors and shapes of blossoms throughout the growing season.

Most of the species are perennials that will grow year after year but some annuals are included to insure rapid first year establishment and flowers as most perennials species are a little slower to flower. Most of the annual species will reseed themselves each year to maintain a presence in your wildflower site.

The Rocky Mountain Wildflower Mix, Great Basin/Colorado Plateau Wildflower Mix, Southwest Desert Wildflower Mix, and the Midwest Wildflower Mix are comprised of only species native to the USA. The Semi-Low Growing Wildflower Mix, Annual Species Wildflower Mix and Value Great Basin/Colorado Plateau Wildflower Mix contain mostly native USA species but also a few introduced species.

Sometimes it may be desirable to plant a moderate amount of non-aggressive, clump-type species of grass with your wildflower mix or possibly a showy ornamental type shrub species. If one of our 7 standard wildflower seed mixes does not cover your needs a custom mix can be made to your specifications.

In order to achieve a successful wildflower-planting project Stevenson Intermountain Seed, Inc. has developed a written “Quick Guide To Successful Establishing a Wildflower Site.” Just ask for a copy.
