Although Crocosmia are half hardy bulbs, they are usually grown as annuals by gardeners.
They have leaves that look like swords (ensiform). These these carry inflorescences that have red or orange funnel like flowers.

It is perhaps easiest to grow Crocosmia from corms. These should be planted at about 10 cm (4 inches) apart, at a depth of between 10 and 15 cm (4 to 6 inches).
If growing from seeds, then they should be sown in the spring. Simply cover the seeds with topsoil.
It may prove easier to start off indoors from seeds. They should be started off about seven weeks before due to be put out, after the last frost of the spring.
They typically take from one to three months to germinate, at about 15 degrees Centigrade (59°F).
Once growing nicely, the Crocosmia seedlings can be transplanted into a location that is a sunny or partially shaded area of the garden.
Once established, the plants should be divided every three years.
If you live in a very cold area, then the corms of Crocosmia should be brought indoors in the winter. Store in a cool place.
It usually takes about two years until a Montbretia plant will bear flowers.
