Barlow Series- This clumping biennial/short-lived perennial reaches 24-36 inches tall and about 12-18 inches wide. It is generally hardy throughout zones 3-9 (especially in well-draining soils), and blooms in mid-spring with a mix of white, pink, carmine, blue, burgundy, bicolor, fully double and spurless flowers on erect stems. The Barlow strain look very unique compared to your typical columbine. All columbines prefer moist, well‑drained soil in part sun to shade. In northern areas, more sun is appreciated - in southern areas with extreme sun, give them more shade. This variety is known to be deer and rabbit resistant. Developed specifically for cut-flower use, harvested stems should last between one and two weeks in a vase. By harvesting the stems down to the leaves, you will encourage the plant to send up a second flush of flowers! Harvest when the first flowers are fully open, but many buds remain on the stem. 

Swan his violet/lavender color is popular in early-season bouquets and pairs well with other soft spring shades. As with most columbines, this variety should be hardy in zones 3 to 9, and is best grown in full sun to part shade with well-drained, fertile soil. More shade should be given in hotter climates to avoid leaf scorch. If left to flower in the field, it will be a magnet for hummingbirds and bees; it's pollinator-friendly, while being deer and rabbit-resistant. These will readily self-sow, but future generations may not look exactly like the parents.
