Mix - Western Foothills (Seed)

Ecoregions: 15 - 17 (Level III)

This drought-tolerant native forb mix provides extended bloom coverage and strong ecological value for open, sunny sites. Flowering begins in late spring and continues through summer into early fall, offering season-long color and consistent pollinator support. The mix performs well in dry, disturbed, or low-input landscapes while contributing to soil stabilization and habitat diversity.
