Basic Characteristics
Freesias are cormous perennials belonging to the Iridaceae family, which also includes irises and gladioli. While they originate from South Africa’s Cape Province region, they have been extensively hybridized to create the diverse range of varieties we enjoy today.
Appearance
Freesia flowers grow on gracefully arched stems that typically reach 12 to 18 inches in height. Each stem can produce 6 to 12 funnel-shaped blooms arranged in a one-sided spike, with flowers that face upward. The narrow, sword-shaped leaves are primarily basal, forming a fan-like arrangement. What makes freesias particularly distinctive is how their flowering stems bend at a right angle, creating their characteristic arching appearance that adds elegance to any garden or floral arrangement.
Fragrance
The fragrance of freesias is truly their crowning glory. Often described as sweet, fruity, and slightly citrusy, their scent is powerful yet refined. White and yellow varieties typically offer the strongest fragrance, though all colors provide some degree of scent. The intensity of their perfume makes them perfect for cut flower arrangements, where just a few stems can fill a room with delightful aroma.
Bloom Time
When planted outdoors in suitable climates, freesias typically bloom in late winter to early spring. In warmer regions (USDA zones 9-10), they can be grown as perennials, while in colder areas, they’re treated as annuals or grown in containers that can be moved indoors during winter. For indoor forcing, bloom time depends on planting date, usually occurring 10-12 weeks after planting.

Growing Freesia
Successfully growing freesias depends on understanding their preferred conditions and providing appropriate care throughout their growing cycle.
When to Plant
Timing is crucial for freesia success. In zones 9-10 where they can be grown as perennials, plant corms in fall for spring blooms. In colder regions, plant in spring after all danger of frost has passed. For indoor forcing, plant corms in pots from late summer through winter for blooms approximately 10-12 weeks later.
Where to Plant
Freesias thrive in full sun to light shade, with afternoon shade beneficial in hotter climates. They need well-draining soil to prevent rot, making them excellent candidates for raised beds. In the garden, choose a protected location sheltered from strong winds that might damage their delicate stems.
How to Plant
Plant freesia corms 2 inches deep and 2-3 inches apart. Position them with the pointed end facing upward. For container growing, use a pot with drainage holes filled with high-quality potting mix. You can plant several corms in a single container for a fuller display, spacing them about 2 inches apart. After planting, water thoroughly and maintain even soil moisture until growth appears.
Container Growing
Freesias excel in containers, which makes them accessible even to gardeners in colder climates. Choose pots at least 6 inches deep with drainage holes. For a stunning display, plant 5-7 corms in an 8-inch pot. Use a well-draining potting mix, ideally with some sand or perlite added. Container-grown freesias can be moved indoors during cold weather and positioned to catch optimal sunlight.
Care Requirements
Proper care will ensure your freesias reach their full potential with abundant blooms and intoxicating fragrance.
Watering
Keep soil consistently moist but never soggy while freesias are actively growing. Reduce watering after flowering as foliage begins to yellow, and allow the soil to dry out completely once the plants have died back. Overwatering, especially during dormancy, is a common cause of corm rot.
Fertilizing
Apply a balanced, water-soluble fertilizer every two weeks from when shoots emerge until flowering begins. Alternatively, mix a slow-release bulb fertilizer into the soil at planting time. Avoid high-nitrogen fertilizers which can promote lush foliage at the expense of flowers.
Support
Freesia stems can become top-heavy when in full bloom. Consider providing light support with small stakes or specialized flower supports, especially in areas prone to wind. Be careful not to damage the corms when inserting supports.
After Flowering
After blooming has finished, continue to water and feed the plants until the foliage begins to yellow naturally. This post-bloom period is crucial for energy storage in the corms for next season’s growth. Once foliage has completely died back, you can dig up the corms in colder regions for winter storage, or leave them in the ground in zones 9-10.
Digging and Storing Corms
In colder regions where freesias aren’t winter-hardy, dig up corms after the foliage has died back completely. Clean off excess soil, allow them to dry for a few days in a well-ventilated area, then store in mesh bags or paper (never plastic) in a cool, dry location around 50-55°F until replanting time.
Design Tips
Freesias offer numerous possibilities for enhancing your garden design with their elegant form and heavenly fragrance.
In the Garden
Plant freesias in groups of 12 or more for maximum visual impact and stronger fragrance presence. They pair beautifully with spring-flowering bulbs like grape hyacinths and early daffodils. Consider creating a dedicated cutting garden section with freesias and other flowers suitable for arrangements.
In perennial borders, freesias work wonderfully with plants that have contrasting forms like rounded geraniums or vertical salvias. Their slender leaves and arching flower stems add a graceful element to more structured plantings.
Fragrance Gardens
Freesias are essential components of sensory or fragrance gardens. Plant them near seating areas or along walkways where their scent can be fully appreciated. Combine with other fragrant plants that bloom at different times of day, such as night-scented stocks or jasmine, for a continuously aromatic garden experience.
Freesia as Cut Flowers
Freesias are prized cut flowers, lasting 7-10 days in arrangements while providing exceptional fragrance.
Harvesting Tips
Cut freesia stems when the first 1-2 buds have opened but the remaining buds are still closed. Harvest in the morning when stems are well-hydrated for best vase life. Use sharp, clean scissors or pruners to make a clean cut at a 45-degree angle.
Conditioning for Arrangements
Immediately after cutting, place stems in room-temperature water. Remove any foliage that would be below the waterline in your arrangement. For maximum vase life, recut stems under water and add floral preservative to the vase water. Change water every 2-3 days to prevent bacterial growth.
Arrangement Ideas
Freesias are versatile in arrangements. Their arching stems create natural movement in bouquets, while their strong fragrance means even a few stems make an impact. Consider these arrangement ideas:
- Monochromatic arrangements using different shades of a single color
- Pairing with roses and eucalyptus for elegant bridal bouquets
- Simple arrangements with just 3-5 stems in a bud vase for concentrated fragrance
- Combining with other spring flowers like tulips, hyacinths, and ranunculus
Common Problems
While relatively trouble-free, freesias can encounter a few issues:
Pests
Aphids and thrips occasionally target freesias, particularly the flower buds and new growth. Treat infestations with insecticidal soap or neem oil. Spider mites may become problematic in hot, dry conditions – regular misting of the foliage can help prevent them.
Diseases
Corm rot is the most common disease, usually resulting from poor drainage or overwatering during dormancy. Virus diseases can also affect freesias, appearing as streaking or mottling on leaves and flowers. There’s no cure for virus-infected plants, which should be removed and destroyed.
Growing Challenges
Failure to bloom is typically caused by insufficient light, improper storage of corms, or inadequate chilling period. Weak, leggy growth usually indicates insufficient light. If plants produce foliage but no flowers, they may need higher phosphorus fertilizer to encourage blooming.
