How to plant
Plant bulbs in early autumn, about 3-4in (8-10cm) deep.
Use a loam-based compost in pots, with added grit for drainage (two parts compost to one part grit).
In borders, choose a spot with well-draining soil, in full sun or partial shade.
If overcrowded, lift and divide the clumps once the flowers have gone over.
Don’t plant in rich soil or overfeed or you will end up with more leaf than flower.
