The perennial freesia grows from a small bulblike structure known as a corm. It stands approximately 18 inches tall with long, narrow, straplike leaves. In the spring months the plant produces flower stems that bear trumpet-shaped, fragrant, dangling flowers. Each stem has up to 12 individual flower heads. The flowers appear along one side of the flower stem in a wide range of colours. Grown as a garden plant or potted house plant, the freesia produces flowers in the winter and spring.

Choose a planting location with full sunlight for the best flowering or place the freesia container in a south-facing window. Add aged manure to the garden soil until the soil feels crumbly to the touch prior to planting the corms.
Dig a hole approximately 5 inches deep in the soil. Set the corm into the soil and firm the soil over the top of the corm. Space each corm 4 inches apart.
Water the corms well. Freesia plants enjoy moist soil conditions and do not tolerate drought well. Continue watering the freesia to keep the soil from drying out until the plant ceases to flower. Once flowering is over, discontinue watering.
Fertilise the freesia plant every two weeks when it's actively growing and blooming. Choose a high-potassium, water-soluble fertiliser. Follow the directions on the label for fertiliser applications. Consider diluting the recommended solution in half to avoid overfeeding the plant.
Clip away spent freesia flower heads using pruning clippers to encourage new flower production. Discard the flowerheads.

- Plant freesia corms in the fall months in the garden in areas that do not suffer inclement winter temperatures. The plant is appropriate for fall planting in U.S. Department of Agriculture zones 9 to 10 but plant in the spring in USDA zones 4 to 8.
- Consider planting freesia corms in planters in the home garden where they can be easily moved indoors if a frost is predicated.
- Freesia plants prefer a nighttime temperature of approximately 10 degrees Celsius.
- Freesia plants can also be grown successfully from seeds.
- The freesia will suffer injury if the temperature drops below 0-3.889 degrees Celsius.
- Choose a dry storage area with temperatures of 77 to 86 degrees Fahrenheit to store freesia corms.
