SYMPHYOTRICHUM ‘VASTERIVAL’

Each autumn as the flowers open I am captivated by this aster’s delicate, airy dominance. Its tall, well-branched, black stems bear slim, dark leaves. In late August small, lilac-pink flowers open into glowing sprays. As one flower fades to almost white, the next opens, giving the plant a three-dimensional quality unusual in asters. May need staking.
