Helianthus annuus or Common sunflowers are easy to grow and hugely popular with kids. They usually flower in mid to late summer, making sunflowers the ideal choice for vibrant colour in July. The large flowers are usually bright yellow, but can also be found in deep oranges and even dark reds.
For an impressively tall sunflower variety, choose ‘American Giant’ which can grow up to 4m tall. Smaller sunflowers are also great fun, such as the ‘Teddy Bear’ cultivar, which can grow to 90cm.
As the name suggests, Sunflowers are sun-loving plants that thrive in plenty of direct sun.
