As much a part of spring as daffodils, the delicate flowers of Columbine form a star of outer petals surrounding an inner ring with yellow centers. Some flowers have spurs that project out behind the blossoms - others are spur-less with double blossoms. All Aquilegia self-sow without being annoying and will yield interesting hybrids if others are close by to pollinate. At home in formal or cottage settings.
