The Intermountain region of the U.S., bounded by the Rocky Mountains on the east and the Cascade and Sierra Nevada mountain ranges on the west. This area includes eastern Washington, eastern Oregon, Nevada, Utah, Idaho, western Montana, western Wyoming and western Colorado. It is also suitable for southwestern Alberta and southeastern B.C. in Canada. The Intermountain Native Wildflower Seed Mix contains annuals and perennials that are native to the Intermountain region. This part of US and Canada, which encompasses states such as Montana, Wyoming, and Idaho, is also home to a diverse range of wildflowers. The soil in this region is varied, with some areas having fertile and moist soil, while others are dry and rocky. The weather in the Intermountain region is characterized by long, hot summers and cold, snowy winters. This extreme range in temperature can be a challenge for some wildflowers, but there are also species that have adapted to these conditions. For example, the Heart-leaved arnica can be found in the moist meadows, while the Sego lily thrives in the dry, rocky soil. Additionally, the Intermountain region receives ample rainfall, which supports the growth of wildflowers such as the Mountain goldenrod and the Rocky Mountain bee plant. Overall, the unique soil and weather conditions in the Intermountain region provide a diverse range of habitats for wildflowers to grow and thrive. Higher elevations above 7000 ft should use the Mountain Native wildflower mix.

The Northwest region includes northern California, western Oregon, western Washington and coastal British Columbia.The growing conditions in the northwest are ideal for a variety of wildflowers. The soil in this region is typically moist and rich in organic matter, providing a solid foundation for plants to root and thrive. Additionally, the weather patterns in the northwest are ideal for wildflowers, with moderate rainfall and cool temperatures providing ample moisture and a moderate growing season. These conditions have allowed for a diverse range of wildflower seeds to take root and grow, including species such as the western lupine, paintbrush, and Indian blanket. Some wildflowers, such as the Columbia lily, require specific soil and weather conditions to thrive and can only be found in certain areas of the northwest. Overall, the combination of fertile soil and moderate weather conditions has allowed the northwest to become a hotbed for wildflower growth and diversity. Higher elevations above 7000 ft should use the Mountain Native wildflower mix.

The Texas and Oklahoma region is known for its diverse range of habitats, from the lush forests of the East to the arid deserts of the West. This diversity extends to the wildflowers that grow throughout the state, which are influenced by the unique soil and weather conditions of each region. In the eastern part of Texas, where the soil is rich and moist, wildflowers such as the Bluebonnet, Indian paintbrush, and Pink evening primrose flourish. Meanwhile, in the drier, western parts of Texas, species such as the Yellow prickly pear cactus and the Globe mallow have adapted to the harsh growing conditions by developing efficient water-storage mechanisms. The climate in Texas is generally warm, with hot summers and mild winters, providing a long growing season for wildflowers.Additionally, the state receives varying amounts of rainfall, with some regions receiving more moisture than others, supporting the growth of a diverse range of species. Overall, Texas provides a wide range of habitats for wildflowers to grow and thrive, making it a hotspot for diversity and beauty. Coastal areas of Texas should consider a Gulf Coast mix. The extreme eastern Oklahoma areas often use the Midwest Native Seed Mix.
