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.

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 ~1,200 GDD — county provides 2,388 GDD Excellent fit

Growing Tips for Freesia in Lincoln County

Direct sow Freesia outdoors after April 19 in Lincoln County when soil has warmed and frost danger has passed.

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.
