Warmer temperatures, an increasing amount of daylight and beautiful flowers are just some of the reasons that people enjoy spring. Native wildflowers make wonderful additions to your garden as well as providing food and shelter for native wildlife. Their brilliantly colored blossoms and interesting shapes will make your landscape a showplace. Because they are perennials, you can welcome their presence year after year, and they require very little care.
