Culture
Easily grown in average, evenly moist, well-drained soil in full sun to part shade. Tolerates a wide range of soils except heavy, poorly-drained ones. Prefers organically rich, moist soils with light to moderate shade. Remove flowering stems after bloom to encourage additional bloom. Keep soils uniformly moist after bloom to prolong attractive foliage appearance. When foliage depreciates, plants may be cut to the ground. It should be noted that seed collected from garden plants or self-seeded plants may not come true because different varieties of columbine may cross-pollinate in the garden producing seed that is at variance with either or both parents.
Biedermeier plants may be grown from seed, may self-seed in the garden and may naturalize in the garden over time. Seed is commercially sold in flower color mixes or by individual flower color.
Noteworthy Characteristics
Aquilegia is a genus of about 70 species of herbaceous perennials from the Northern Hemisphere.
Genus name comes from the Latin word for eagle in reference to the flower’s five spurs which purportedly resemble an eagle’s talon.
Common name of granny's bonnet is in reference to the spreading bonnet-like appearance of the flower petals.
The Biedermeier Group are a mix of compact, low-growing, columbine plants. This strain contains four separate pastel-colored spurred flowers in colors of pink, red, blue and white. These are bushy, clump-forming perennials that typically grow in a mound of thin, branching, leafy stems to 12" tall. They are noted for having a glorious spring bloom (April-May in St. Louis) of spurred flowers. Biternate, medium green, basal leaves are glabrous above and glaucous beneath. Upper leaves are divided into lobed leaflets that are usually three-lobed at the tips.
Problems
Susceptible to leaf miner. Aphids are a lesser problem. Potential disease problems include leaf spot, powdery mildew and rust. Foliage usually declines by mid-summer at which point it should be cut to the ground.
Uses
Borders, rock gardens, cottage gardens, open shade gardens, woodland gardens or naturalized areas. Also a good selection for a hummingbird garden. Continue to water plants after bloom to enjoy the ground cover effect of the foliage.
