This mixture, from the Earlybird series, was bred for vibrant colors, neatly mounded habit and unusual color combinations. Single colors and may include doubles like purple white, purple yellow and red yellow usually with a yellow eye. They feature a controlled habit, with relatively short stems on well-mounded plants. Flowers are attractive to hummingbirds. Removing spent flowers will increase the blooming time. Since Columbines are relatively short lived, allow some of the plants to go to seed and self sow, however, resulting seedlings may not resemble the mother plant. Leaf miners or sawfly may disfigure the leaves around flowering time. Simply trim off the ugly foliage and the plants will grow fresh leaves.
