Notes
'Alba' knapweed (Centaurea Montana 'Alba') is a perennial for borders, cottage gardens, pollinator gardens, and cut flowers. It is hardy to USDA zone 3, or down to -40°F (-40°C). This plant likes full or part sun and dry to moist soil of most types. It grows in a rapid clump about 12 to 24 inches tall. Butterflies and bees visit the blooms, and it is drought tolerant.
Pairs well with Lanceleaf coreopsis, Columbine, and Caramel coral bells.
