Asteraceae

Botanical Name

CENTAUREA montana

Plant Common Name

Mountain Bluet, Perennial Cornflower

General Description

Native to the mountainous regions of Central Europe, mountain bluet is a perennial that thrives in temperate climates with drier soils. Plants form low mounds of gray-green, lance-shaped leaves from which arise stems of single blue feathery flowers in late spring to summer. This montane plant is great for rock or alpine gardens as well as perennial borders. Plants tend to self-seed, so spent flowers should be removed. Divide these perennials every two to three years for best growth.
