Buying Guide
What seed type should I choose?
- Open-pollinated vs. hybrid: Open-pollinated varieties (like Mammoth and Mammoth Grey Stripe) produce seeds that gardeners can save and replant. Hybrids can offer uniform growth but seed saving is limited.
- Plant height and bloom size: If you want a dramatic backdrop or border focal point, choose varieties known for tall stalks and large heads (up to 12 ft tall).
- Germination and storage: Look for SEED counts that align with your plot size; purchases with resealable packaging help preserve germination quality.
Where should I plant sunflowers?
- Full sun: Sunflowers thrive in at least 6–8 hours of direct sun daily.
- Soil and spacing: Well-drained soil; space plants according to variety to prevent crowding and ensure air circulation.
- Watering: Regular watering during establishment; reduce watering once established to encourage sturdy stems.
What are practical uses for large sunflowers?
- Decorative borders and privacy accents in gardens.
- Pollinator habitats by attracting bees and butterflies.
- Seed harvests for future planting or culinary uses where applicable.
Key purchase considerations
- Seed count per bag and expected plant count.
- Height potential and bloom size for planning beds and landscape design.
- Open-pollination status and compatibility with local pollinator populations.
