Alpine aster is a compact, early flowering Michaelmas daisy that is ideal for rockeries and the front of dry, sunny borders. This Aster alpinus Mixed collection produces masses of daisy-like flowers in shades of pink, purple, lilac and mauve in late spring and early summer. These hardy, drought-tolerant herbaceous perennials thrive in poor soils and dry sites. Rock asters are also great for containers. Height: 25cm (10in).
