How to grow Helianthus (sunflowers)

Sunflowers (Helianthus), with their familiar large yellow blooms, are easy and fun to grow, for children and adults alike. But why limit yourself to the traditional favourites? There’s a colourful array to choose from, in all sizes, both short-lived annuals and long-lived perennials. Ideal for cheering up summer borders and containers, they’re great for attracting wildlife too.
