They can be also used as cut flowers and are raised for this purpose by professional growers.

They are easy to grow from corms or bought as small plants from the nursery or garden centre. They can be bought as dormant corms throughout the autumn and winter and planted right away. When you are planting Crocosmia, always plant the corms at least 10 cm below the soil level and with a space between corms of at least 15 cm. Crocosmia is happy in full sun to part shade. Soil type is almost no problem, though average to loamy, well-drained drained soils seem to suit Crocosmias better. Will normally survive and even thrive in drought conditions. But they will not survive in soils that are water logged.

Instructions:
