Freesias are fragrant, herbaceous perennials belonging to the Iridaceae family. Native to South Africa where they blossom in winter when the temperature cools and the rainy season begins. They are beloved by gardeners and florists alike for their vivid, colourful blooms and their longevity as cut flowers which give off their fresh and fruity perfume for up to three weeks.
What do freesias look like though? Freesias have slender green stalks which are densely clustered around the stems and usually crowned with six to twelve funnel-shaped or fluted petals. They typically reach a mature height of between 12 and 20 inches. Their elegant blooms display a range of colours such as white, yellow, orange, red, pink, and purple, depending on the variety.
Freesias are zygomorphic, meaning their flowers emerge from only one side of the stem. Often, the brightest coloured varieties have the strongest scent. It’s estimated that there are as many as 1800 different types of Freesia spanning 16 species, each with its own unique colouring.

How to Grow Freesias
Freesias are best grown from the corm, a bulb-like tuberous structure. To set yourself up for success, choose larger and better-developed corms when purchasing from nurseries or garden centres as they store more energy and will produce much stronger and healthier blooms than smaller corms.
Often, Freesias are sold as ‘prepared’ corms, which means they have been heat-treated to mimic the South African summer. This process stimulates blooming around 100-120 days after planting. Freesias become dormant in very hot weather, and need cool temperatures to break the dormancy so that they can begin to flower. You can also purchase Freesias as ‘unprepared corms’ with slightly different growing requirements.
Freesia corms can be planted indoors between August and December for late winter and early spring blooms. When planting indoors, ensure the pot has adequate drainage holes and make sure the soil around the corm remains loose, giving it plenty of room to spread its roots. Plant your corms around two inches below the surface, with around three to four inches of soil beneath the corm. Use a well-draining potting mix.
Water regularly but sparingly until new growth appears and place the pot in a warm, bright position for around eight weeks. When the shoots are around two inches tall, transfer the pot to a cooler position to stimulate flowering. Try to avoid very sunny positions, as too much heat and light will cause your pretty flowers to fade.
Planting Outdoors in the Ground
Outdoors, Freesias prefer a warm and sheltered location with plenty of indirect sun. ‘Prepared’ Freesias should be planted outdoors from April to June once the last frost has passed for late summer flowering. ‘Unprepared’ freesia corms should only be planted in late summer and will flower the following spring.
Plant your corms at a depth of around two inches, and space them about two to three inches apart. You can cover the corms with a layer of mulch for added protection. If planting directly into the ground, make sure the soil is well-draining, and add extra drainage material if necessary. Keep the soil lightly moist until the first shoots appear, after which, weekly watering should suffice.
Planting Outdoors in Containers
It’s possible to start corms off slightly earlier in pots than ground corms, provided they are kept under cover until frost has passed. When the weather warms, move the pots to their intended position in the garden. Like indoor Freesias, outdoor potted Freesias will need well-draining, loose soil, and plenty of drainage holes in the pot. Keep the potting soil moist until the first shoots emerge.
Alternatively, you can plant potted corms in a cold frame or greenhouse between August and December for winter blooms the following year, between January and April.
Freesias love fertile, well-draining soil with a pH level that is neutral to mildly alkaline. In the ground, a loamy, stony, or slightly sandy soil is ideal. If grown in pots, use a potting mix of around two parts compost to one part drainage material, such as perlite or horticultural grit.
Freesias love a position where they will receive full to dappled sunlight. Too much sun causes their flowers to fade and wilt, so select a sheltered position where they are protected from the most powerful midday rays. Different varieties will have different light requirements, so check this out when purchasing.
Freesias are temperature-sensitive, and won’t tolerate extreme temperatures. If temperatures consistently exceed 15°C, they can become spindly, and their vibrant colours will begin to fade.
Freesias cannot tolerate frost and need a consistent minimum winter temperature of between 4 and 7°C if they are to return the following year. If you live in a colder climate, it’s best to treat them as annuals and store them indoors over winter
Freesias don’t like very wet soil, particularly when they are young. Seedlings should be watered sparingly but regularly to keep the soil lightly moist. When established, once-weekly watering should be enough to keep them happy. Overwatering causes the blooms and foliage to wilt and the corms to rot.
Continue watering your Freesias regularly until the foliage begins to yellow and fade at the end of the growing season.
After the first buds emerge, feed your young Freesias fortnightly with a well-balanced, high-potash fertiliser. Freesias require less food if the soil is already nutrient-rich.
Because of their top-heavy structure, Freesias usually require extra support to stop them from breaking under the weight of their beautiful blooms. Create supports by using small lengths of garden cane, twigs, or pea sticks secured with twine.
You can remove faded, wilted, or dead flowers during the growing season by snipping them where they meet the stem. Once the stems begin to wilt at the end of the season, prune the flower stalks from the main stems. Don’t be tempted to prune wilting foliage too early though, as they are vital for collecting extra energy to be stored in the corm for the following year.
In warmer climates, Freesia corms can be left in the ground over winter and covered with a generous layer of mulch to protect from lower temperatures. In colder climates, however, you will need to dig up the corms at the end of the growing season, either once the foliage has died back or before the first frost arrives. The corms can be stored for replanting the following year. When the weather drops, potted freesias can be moved to a greenhouse or indoors and placed back outside after the last frost has passed. You might want to repot these corms with fresh soil, as Freesias tend not to like flowering in the same pot twice.
Storing For Replanting
To store corms over winter for replanting, lift the bulbs and cut the stem down to around two inches, before allowing the corm to completely dry out for around three weeks. This drying process is known as ‘curing’. Once dried, target rid of any shrivelled corms, keeping only the healthy, plump bulbs. Store your corms in a cool, dry, dark place. Sandboxes, newspapers, and paper bags are generally good storage mediums.
Growing Freesias from seed
Have you ever thought how to grow freesias? In addition to corms, Freesias can also be grown from seed, although this growing method typically takes several years for blooms to emerge. If you are a patient gardener, you can collect your own Freesia seeds from established plants. Seed pods develop after the plant blooms. They should be left on the plant to ripen throughout the growing season. Once the pods begin to dry out in late summer and early autumn, the seeds can be safely collected and stored in a cool dry place until you are ready to plant them.
You should always soak Freesia seeds in warm water for 24 hours before planting them to stimulate growth. The seeds should then be sown in trays of compost and kept moist (but not wet). Once the green leaves begin to emerge from the seedlings, you can transplant them to pots and left to acclimatise outdoors when temperatures reach around 15°C. Once acclimatised fully, you can transfer your Freesias to their intended growing position.
