Culture

Easily grown in average, medium moisture, 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. Plants may be easily grown from seed, will self seed in the garden and will naturalize in the garden over time. It should be noted, however, that seed collected from garden 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.

Noteworthy Characteristics

This double aquilegia has striking, deep purple flowers that look almost black. In the garden, Black Barlow is a strong grower and reliable bloomer. It flowers in early summer and usually blooms again in late summer. Long, stiff stems make it an excellent cut flower. Aquilegia vulgaris known as columbine (also commonly called European crowfoot and granny's bonnet) is native to Europe. It has escaped gardens and naturalized in parts of eastern North America. It is a bushy, clump-forming perennial that typically grows in a mound of thin, branching, leafy stems to 1.5-3' tall. It is noted for its spring bloom (April-May in St. Louis) of blue to violet flowers with spreading sepals and short-hooked spurs. 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. Many different cultivars are available in commerce, featuring flowers that are single or double and short-spurred or spurless, in a variety of colors ranging from blue to violet to white to pink to red.

Genus name comes from the Latin word for eagle in reference to the flower’s five spurs which purportedly resemble an eagle’s talon.

Specific epithet comes from the Latin word meaning common.

Columbine comes from the Latin word columba meaning dove-like. Common name of granny's bonnet is in reference to the spreading bonnet-like appearance of the flower petals.

Garden 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.

Knowing your Hardy Zone

Below is a USDA Hardiness zone map. Simply pick your state, pinpoint the area in which you live then match your color with the color coded chart to find your hardiness zone. I'll use myself (area) as an example; I have a plant that is hardy in zones 4-8 and am located in North Idaho. On the map it shows that my color is dark green which is zone 6a so following the planting and care instructions given for this plant, I will have great success in growing this plant in my garden!
