One of my personal favourites.
|USDA Hardiness Zone|
|3 - 9|
|30 - 40 cm|
|Well drained, good garden soil in full sun to partial shade. Dead heading after bloom will encourage strong plants. About every five years or as the number of blooms decrease lift clumps with a fork after the foliage has withered. Pull the bulbs apart and detach any offsets, replant bulbs three times their own depth and depending on plant size 3-10 cm apart.|

|Division of offsets when foliage has yellowed and ripened in mid-summer.|
