Aster alpinus 'Dark Beauty'
A little wee species which is ideal for a trough or pot, or a special little spot along the edge of a garden bed where it can't get smothered. Forms a very low spreading clump of green leaves at ground level, and in spring and early summer dark violet-blue daisies appear on short stems, followed by fluffy seedheads. Prefers full sun and good drainage in average soil. Flowering height 20cm, spread 20-30cm. 9cm pot.
