Sunflowers are more than just a novelty to grow in the summer. Helianthus, the annual sunflower, Helianthus anumus, and many other cultivars are all part of the genus Helianthus. There are also many other perennial and annual species in Helianthus. Some of these species can be grown as vegetables, such as the Jerusalem artichoke Helianthus tuberosus.
Small Sunflower Heads
Sunflowers are wonderful cut flowers. If you are growing them for their flowers, cut off the tips of each plant at 20cm. This will result in many smaller flower heads than one large flowerhead.
Don’t forget to plant some sunflower heads when you are growing them. The nectar and pollen will be enjoyed by the bees in large numbers, while the sunflower seeds will be appreciated by the garden birds in the autumn.
Sunflower growing conditions
Sunflowers, like their name implies, love the sun so plant them in the best spot. Just before they flower, give them a good watering and a little bit of tomato feed.
