Helianthus 'Double Whammy'

Sunflowers flower throughout the hottest part of the summer. Their flower heads famously follow the sun throughout the day and hang down over night! A stunning site throughout many regions of mid and southern France and Italy where they are farmed for the oil. Very bee friendly.

Plant out container grown plants.

Sow seeds under glass for planting out in spring.

Sow seeds into flowering position after last frost.

Once the frosts have passed it is time to plant sunflowers into the garden. If planting straight into the soil, look for a sunny position with shelter from winds. A position against a wall is usually best. Try to avoid sandy soil and rich-free draining soil will be most successful. Plant the seeds about 30cm apart and about 3cm below the surface. Sunflowers do like a lot of water so to get the best out of your plant try to water it every day, but keep and eye on the soil and roots as constantly damp and soggy roots will make the plant unstable and good lead to root rot.
