Seed and Plant Details
Why Grow Galaxy Sunflowers?
- Classic golden-yellow flowers with contrasting dark centres.
- Tall plants add height to sunny borders and garden beds.
- Pollen-free blooms for tidy indoor arrangements.
- Good vase life makes it useful for bouquets and floristry.
- A practical choice for home cut flower gardens and commercial flower growing.
Garden Displays and Cut Flowers
Plant Galaxy in groups towards the back of sunny borders or grow in dedicated cut flower beds. Position the plants where their height will complement surrounding flowers without shading smaller sun-loving plants.
Cut stems as the petals begin to open and place them promptly in clean water. Remove leaves that would sit below the waterline, use clean cutting tools and refresh vase water regularly.
How to Grow Galaxy Sunflowers
- Choose a growing position. Select a sunny site with well-drained soil and shelter from strong winds.
- Prepare the soil. Loosen the planting area and incorporate mature compost where needed. Avoid areas that remain waterlogged.
- Sow the seeds. Plant approximately 1 cm deep and water gently. Direct sowing avoids disturbing developing roots.
- Maintain moisture. Keep the seedbed moist without saturating it until seedlings establish.
- Thin and support. Allow approximately 30–40 cm between plants. Install stakes or support netting early in exposed positions. Transplant pot-raised seedlings while young with minimal root disturbance.
- Water and feed as needed. Water thoroughly during dry weather, particularly as buds develop. Apply a suitable fertiliser according to its label where needed.
- Enjoy or harvest the flowers. Leave blooms for garden colour or cut stems as the petals begin opening for bouquets.
