Buying Guide: Key Considerations For Sunflower Seeds
- Height and growth habit: Choose varieties to fit space constraints (dwarf, mid-height, or mammoth giants).
- Bloom color and head size: Consider a mix of yellow, orange, or striped varieties and head diameters for visual impact.
- Germination and vitality: Look for open-pollinated or non-GMO options with high germination rates for reliable stands.
- Pollinator support: Many sunflowers attract bees and birds; select mixes if wildlife gardens are a goal.
- Soil and climate adaptability: Some packs emphasize broad climate tolerance; match to your USDA zone and soil type.
- Seed saving potential: If you’d like to harvest seeds, favor open-pollinated varieties rather than hybrids.
- Planting density and spacing: Taller varieties require more space; plan borders, fences, or rows accordingly.
