Growing Tips

Sow seeds directly into the ground in a sunny, sheltered position. As a tap-rooted plant, water deeply but less frequently to encourage strong roots. Because of its tall height, provide support such as staking, wires, or planting alongside a windbreak to prevent stems from toppling. Adding compost or a slow-release fertiliser at planting will boost growth and flower size.

Harvest & Display

The bold blooms of Tall Timber F1 are perfect for cut flowers, offering long stems and excellent vase life. Outdoors, they create dramatic garden displays, towering above borders and adding instant vertical interest. With their vibrant golden petals and impressive size, Tall Timber sunflowers bring a touch of grandeur to any garden or bouquet.
