Sunrich Summer Provence is an F1 hybrid sunflower bred for earlier blooms and more reliable performance than standard varieties. These compact plants reach maturity in just 60-65 days, delivering abundant cut flowers from midsummer onward. Hardy from zones 2 to 11, this variety thrives in moderate water and well-draining soil, making it accessible to gardeners across nearly every climate. Direct seeding after the last frost is recommended, though it can be transplanted if started indoors 2-3 weeks ahead of planting out. The Sunrich lineage represents a deliberate improvement in genetics, prioritizing florist-quality stems and consistent blooming.

Sunrich Summer Provence flowers can be harvested at multiple stages depending on your needs: tight and just showing color for longer vase life, or nearly fully open for immediate impact. The compact growth habit means you can space plants closely at just 4 inches apart, letting you pack more productivity into smaller garden beds or cutting rows. This hybrid's 60-65 day timeline positions it perfectly for successive plantings every 1-2 weeks, ensuring a continuous supply of blooms throughout summer and into fall.
Sunrich Summer Provence excels as a premium cut flower for arrangements, vases, and floral design. The harvest flexibility described in seed catalogs, from tight buds to near-full bloom, allows florists and home arrangers to condition flowers for specific uses. Its compact habit and prolific blooming also make it valuable in garden settings where continuous summer color is desired.
No timeline data available yet for this variety.
Sow seeds into 72 to 50-cell flats 2-3 weeks prior to your intended transplant date. This early start allows you to get a first crop of flowers into the garden earlier than direct seeding alone. Keep soil moist at 50-75°F until germination, then maintain consistent moisture until transplanting.
Transplant after the last frost date when seedlings have developed their first true leaves. Space plants 4 inches apart. Handle carefully, as sunflowers dislike root disturbance; transplanting is possible but requires gentle handling to minimize transplant shock.
Direct seed 1/2 inch deep into warm soil after the last frost date. This is the recommended method. Space seeds 4 inches apart or thin to 4-inch spacing once seedlings emerge. Succession-sow every 1-2 weeks for continuous blooms throughout summer.
Cut flowers when color first shows on the petals for maximum vase life, when color is well-developed for a fuller look, or when petals are almost completely open depending on your preference and intended use. For dried flowers, allow blooms to open completely before harvesting. Hang-dry or use silica gel to preserve dried blooms.
Do not pinch or pinch back this variety. Pinching single-stem sunflowers produces low-quality blooms or no blooms at all. Allow plants to develop naturally without topping.
