Tightly packed clusters of lilac-blue, tubular flowers form at the tops of the tall, upright stems in early summer, just as the grass-like foliage is starting to die back. Thriving in a sheltered spot with plenty of sun and freely draining soil, it works well in both herbaceous borders and prairie-style settings.
How to care for Dichelostemma congestum:
Plant corms 10cm deep in autumn in well-drained soil. Keep dry after flowering and apply a generous layer of insulating mulch around the crown in autumn to keep it warm. In colder areas, it may be best to pot it up so it can be overwintered in a cool greenhouse.
