An elegant cultivar with an abundance of pale lilac-pink flowers in the autumn. When most other hardy perennials are starting to fade, Aster novi-belgii 'Chatterbox' bursts into bloom, adding a splash of colour to borders that will last until October. This lovely Michaelmas Daisy has a neat bushy habit that makes it equally at home in patio containers. Height and spread: 40cm (16?).
