Award-winning Little Carlow Aster is completely covered by clusters of petite, sky-blue flowers with yellow centres from late summer into fall. Butterflies and pollinators flock to the blooms. A hybrid cross of Aster cordifolius and Aster novi-belgii, this easy-care perennial grows 32" tall with a similar spread--perfect for tucking near walkways, in a container or other places that need a pop of radiant blue.
