'Wonder of Staffa' is a summer-blooming aster cultivar with lavender-blue flowers and bright yellow eyes. Plant is rounded to mounded, growing about 3 feet tall and wide. Leaves are green and small. It blooms from early summer into the fall, sometimes until the first frost. Use in perennial borders or with ornamental grasses; also a lovely cut flower. Loved by butterflies.
Grow in average, medium to dry, well-drained soils in full sun to part shade. Pinching back stems in late spring will lower overall plant height, but will also delay bloom onset and increase branches, increasing the number of blooms. A light winter mulch will help protect crowns. Cut stems to the ground in early spring before new growth appears. Wet soils in winter can be fatal.
