Planting wildflower seed is a popular way to enhance a wildlife area or sunny meadow, attract pollinators and bees, or eliminate mowing on hillsides and other difficult-to-mow areas. Wildflowers may be annuals, biennials or perennials. Many wildflower annuals reseed themselves, so there is no need for sowing year after year. Black-Eyed Susan, Shasta Daisy, Coreopsis and Coneflowers are some of the most popular wildflowers to grow. When selecting wildflower seed packets, the two most important factors to determine are if the wildflowers are suitable for your hardiness zone and your light requirements (full sun, partial shade or full shade). Another factor to consider is how many square feet each seed packet covers.
