Crocosmia is a South African native perennial flowering plant and a member of the iris family. Crocosmia is a popular bedding and border plant because of the gladiolus-like red, orange and yellow flowers that bloom in summer until fall. Generally started from bulbs, or corms, crocosmia is also easily propagated from seed. Sow the seeds indoors in February.
Fill the seed tray with seed starting mix to within 1/4 inch of the rim. Water the soil until the water drips from the bottom of the tray. Allow the soil to drain completely.
Push the seeds 1/4 inch into the soil and barely cover with soil. Crocosmia seeds require light to germinate.
Place the seed tray in an area that receives lots of light, but out of direct sunlight, and remains 68 to 70 degrees F. Keep the soil moist, not soggy, by misting it with a plant-misting bottle. The crocosmia seeds should germinate in two to four weeks.
Transplant the seedlings outdoors, in a sunny area, in late spring when temperatures are consistently above 65 degrees F.
