Seed and Plant Details
Why Grow Solar Flash Sunflowers?
- Golden-yellow and bronze flowers with contrasting dark centres.
- Compact plants suited to containers and smaller garden spaces.
- Branching growth produces several flowers per plant.

Garden Displays and Cut Flowers
Plant Solar Flash in groups along sunny borders or grow in containers near outdoor seating areas. Its manageable height makes the flowers easy to enjoy up close.
Cut suitable stems as the petals begin to open and place them promptly in clean water. Remove leaves that would sit below the waterline, and leave developing side buds for further garden colour.
How to Grow Solar Flash Sunflowers
- Choose a growing position. Select a sunny site with well-drained soil or a container with drainage holes.
- Prepare the soil. Loosen the planting area and incorporate mature compost where needed. Use quality potting mix for containers.
- Sow the seeds. Plant approximately 1 cm deep and water gently. Direct sowing avoids disturbing developing roots.
- Maintain moisture. Keep the seedbed moist without waterlogging it until seedlings establish.
- Allow room to branch. Thin seedlings to approximately 20–30 cm apart. If raising seedlings in pots, transplant while young with minimal root disturbance.
- Water and feed as needed. Water thoroughly when the soil begins to dry. Feed container plants according to the fertiliser label.
- Enjoy the flowers. Leave blooms for garden colour or cut selected stems for arrangements. Remove faded flowers to keep the display tidy.
