Freesias (Freesia spp.) are prized above almost all other cut flowers for their intense, sweet fragrance — a single stem can fill a room. Slender, arching stems carry one-sided sprays of funnel-shaped flowers in white, yellow, pink, orange, red, purple, and lavender. Native to South Africa's Cape region, freesias thrive in cool, mild weather and go dormant in summer heat, making them ideal for mild-winter climates where they bloom in late winter through spring. The 'Marilyn', 'Blue Heaven', and 'Yellow Rivers' cultivars are staples of the commercial cut flower trade.

Osceola County, Florida is in USDA Zone 10a. The average last spring frost is January 22 and the first fall frost is December 20, giving you a growing season of approximately 332 days.

At an elevation of 352 feet, Osceola County receives approximately 58.7 inches of rainfall annually with predominantly sand soil. Summer highs average 102°F, so Freesia may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Freesia will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Freesia root diseases.

Freesia Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Freesia needs ~2,597 GDD — county provides 8,824 GDD Excellent fit

Growing Tips for Freesia in Osceola County

Direct sow Freesia outdoors after January 22 in Osceola County when soil has warmed and frost danger has passed.

Sandy soil in Osceola County dries quickly — mulch Freesia with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

With summer highs reaching 102°F in Osceola County, provide afternoon shade for Freesia and water deeply in the morning.

General growing tips

Plant corms 2 inches deep with the pointed end up, 2–3 inches apart, in autumn (September–November in zones 8–10). Full sun and excellent drainage are essential — freesias rot in soggy soil. They need cool but frost-free growing conditions (40–60°F nights) to initiate flower buds; warm nights above 70°F suppress bloom. In zones 8–9, provide a winter mulch if hard frost threatens. After flowering, allow foliage to yellow and die back naturally; this ripens the corm for the following year. In zones 8a–9b, corms may multiply and naturalize over time but perform best when replanted fresh each fall. In zones 10–11, plant from October through December for a January–April bloom. Freesias are toxic to cats and dogs.
