Loose spires of blue or lilac, star-shaped flowers appear on top of tall stems in late spring. Originally from damp meadowlands in North America, this bulbous perennial is perfect for naturalising in a wildflower meadow. It will happily grow in moist soil or partial shade as long as the soil doesn't become waterlogged. Take advantage of its brief flowering season to brighten up a border before summer perennials take over.
- Garden care: Plant the bulbs 8cm deep and 20cm apart in big groups in the autumn. Try to plant them where they will remain for several years as they resent being moved. In cold areas, apply a generous layer of mulch in autumn.
