What time of year is best for sunflowers?

Sunflower seeds should be planted between April and May in 10cm pots of peat-free, multi-purpose compost. Cover the pots with a plastic bag and place them in a warm spot for optimal germination. Once the seedlings emerge, harden them off gradually for two to three weeks before planting them outdoors. If your garden has a lot of slugs and snails, consider potting them into larger pots of fresh compost and hardening them before planting them.

How do you tell if a sunflower is annual or perennial?

Annual sunflowers have large or small seed heads, while perennial sunflowers have only small seed heads. They bloom the first year after planting from seeds, while perennial sunflowers do not bloom for at least two years. Annual sunflowers have string-like, shallow roots, while perennial sunflowers have deeper roots. Post-winter emergence starts in early spring, while annual sunflowers show up in late spring. Germination is faster in annual sunflowers, while perennial sunflowers grow slower.

Non-hybridized perennial sunflowers have few seeds due to their roots and smaller seeds. Annual sunflowers spread through their seeds, resulting in many large seeds. However, modern hybridization has led to more seeds on flower heads. Annual sunflowers grow from single stems spaced out, while perennial sunflowers grow in clumps with many stems coming out of the ground.
