Pansies (Viola × wittrockiana) are beloved cool-season annuals offering some of the widest color range in the annual garden. Their cheerful "faces" appear in early spring — or even late winter in mild climates — and hold up remarkably well through frosts. Heat causes them to go leggy and stop blooming; replace with warm-season annuals once daytime temps exceed 70°F.

Calhoun County, Texas is in USDA Zone 9b. The average last spring frost is February 16 and the first fall frost is December 7, giving you a growing season of approximately 294 days.

At an elevation of 215 feet, Calhoun County receives approximately 59.5 inches of rainfall annually with predominantly loam soil.

Pansy 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.

Pansy needs ~1,940 GDD — county provides 7,153 GDD Excellent fit

Growing Tips for Pansy in Calhoun County

Direct sow Pansy outdoors after February 16 in Calhoun County when soil has warmed and frost danger has passed.

With summer highs reaching 99°F in Calhoun County, provide afternoon shade for Pansy and water deeply in the morning.

General growing tips

Start indoors 10-12 weeks before last frost for spring transplants. In zones 6+, fall planting (8-10 weeks before first frost) gives overwintering plants that bloom earliest in spring. Plant in full sun in cool weather; afternoon shade helps extend bloom in zones 7-8. Deadhead to prevent premature seed set. Shear back by one-third when plants go leggy to extend the season.
