🌿Annual

SOW
Start indoors in February or March in individual pots or modules, about 1cm deep, at around 20°C. Germination takes 1–2 weeks. In milder areas, you can also sow outdoors in April, either in pots or direct where they’re to flower.

GROW
Harden off and plant out once frosts have passed, spacing them 40–50cm apart. Keep well watered and choose a sunny, open spot. Stake tall varieties, especially if you're using them as a screen or windbreak,

ENJOY
Cut these classic sunflowers to brighten your home or let them shine in your garden. Roast the seeds for a tasty snack or dry and grind them for baking. You can also dry the heads and hang them out for birds to enjoy during winter.

WILDLIFE FRIENDLY

• Large, open blooms are a big hit with bumblebees, honeybees, and solitary bees like leafcutter bees.
• Provides a rich nectar and pollen source through mid to late summer.
• Once the flowers fade, the seed heads are a feast for birds—especially goldfinches, sparrows, and greenfinches.
• Great for adding late-season support to wildlife-friendly gardens
