Freesias are part of the iris family and grow from perennial corms, a kind of tuberous seed. Freesias have 12- to 18-inch-long fan-like or sword-shaped leaves and clusters of delicate, fragrant trumpet-shaped flowers. Freesia flowers can be white, yellow or gold, orange, pink, red or purple. You can start your freesia corms indoors about one month before the last expected frost, if you live in a colder region, planting them outdoors in the spring. In warmer climates that don't experience hard frosts or freezes, you can plant the freesias in autumn.
Fill a small container with water and place seven or eight freesia seeds in it. Soak the freesia seed in room-temperature water overnight.
Fill a 5-inch-diameter planter pot with well-draining compost. Remove the seeds from the water and spread the freesia seeds on top of the compost with the corms' tips pointing upward.
Spread a quarter-inch-thick layer of compost on top of the freesia seeds. Water the compost and seeds thoroughly to evenly moisten them.
Place the planter pot in a shady area and maintain air temperatures of around 68 degrees Fahrenheit. Water the seeds only lightly to prevent the compost from drying out completely.
Move the planter pot into full sunlight after the seeds germinate and begin to grow, usually after about 10 to 15 days. Water the freesia seedlings two or three times per week, allowing the compost to dry out slightly before watering.
