Seed and Plant Details
Why Grow Golden Prominence Sunflowers?
- Warm golden petals with a contrasting red ring and dark centre.
- Upright stems for adding height to sunny borders.
- Pollen-free blooms suited to cut-flower arrangements.

Garden Displays and Cut Flowers
Plant in groups towards the back of sunny borders or grow in rows for cutting. Choose a sheltered position where the tall stems have room to develop.
Cut stems as the petals begin to open, preferably during the cooler part of the day. Place promptly in clean water and remove leaves that would sit below the waterline.
How to Grow Golden Prominence Sunflowers
- Choose a growing position. Select a sunny site with good drainage and some protection from strong winds.
- Prepare the soil. Loosen the planting area and incorporate mature compost where needed.
- Sow the seeds. Sow approximately 1 cm deep directly where the plants will grow. Water gently after sowing.
- Maintain moisture. Keep the seedbed evenly moist without waterlogging it while seeds germinate.
- Thin the seedlings. Allow approximately 30 cm between plants. Transplant pot-grown seedlings while young, keeping their roots intact.
- Support developing plants. Water deeply as needed and provide stakes or support in exposed positions.
