Columbines are charming perennials that have been increasing in popularity in recent years. Their unique flowers bloom with colorful pastels. They are bi-colored in shades of lavender, yellow, red and white. They like part shade to part sun. They bloom from May until late June. When Columbines are blooming, they tend to attract hummingbirds, who feast on their nectar. They are excellent additions to a wildflower garden, beds, borders, or rock gardens.
