Sunflowers can reliably turn any frown upside down. Bright and cheery annual blossoms that start to flower in mid summer bring a smile no matter what colour or size you choose to grow. Sunflowers can be planted in so many ways, even as a small flowering hedge that gives continuous colour right into the fall. Grow large types as cutflowers or dry for seed to feed the birds. Sunflowers are known to captivate many different types of pollinators. Plant in full sun for best impact.
