The Sunrich series of sunflowers haven been bred specifically for cut flower production. The Sunrich Summer varieties bloom approx 10 days earlier than the traditional Sunrich series. Sunrich Summer Provence is the essence of summer, with a double row of petals and golden yellow blooms with. a dark centre.

Sow under cover 3-4 weeks before your last frost date; sow outside or plant out after risk of frost has passed. Sow in succession until June for a continuous harvest. Sowing temp 18-21°C; germination between 7-14 days in optimum conditions. Do not pinch! 

Cut sunflowers as the first couple of petals begin to lift off of the flower bud. Sunflowers cut fully open are easily damaged in transit, and pollination reduces vase life. Place immediately into water; no special conditioning requirements.

Vase life: 7-10 days
