THERE pint-sized bulbs in shades of blue and white produce their narrow, leafless flower stems in early spring before the dense spikes of flowers appear.
Types such as M. azureum, which has pale blue flowers with conical heads, look lovely in a rock garden or at the front of a border. They are best planted in abundance in terracotta pots, which act as a perfect foil for deep blue varieties such as M. armeniacum and M. neglectum.
Also, pots prevent the bulbs from taking over an area, as some varieties can be invasive.
Plant bulbs in autumn in containers or massed together in borders or in grass, where they may naturalise. They prefer moderately fertile, well-drained, sandy soil in a sunny spot. Separate offsets or divide clumps in summer.
