When to Plant Freesia in Pinal County
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.
Pinal County, Arizona is in USDA Zone 9a. The average last spring frost is February 23 and the first fall frost is November 27, giving you a growing season of approximately 277 days.

Growing Tips for Pinal County
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.
