Sunflowers are sometimes grown purely for their ornamental value but they have a very wide variety of uses. The seeds, once processed, make a delicious snack and unprocessed can be fed to birds, livestock and other animals. A single sunflower can produce up to 2000 seeds. The petals can be used to make dye. The taller varieties can be used to make a natural windbreak and you can even use them as a living pole to support climbing beans.
Sow seeds 2.5cm deep, 15cm apart and they usually germinate in 10 days. Thin larger varieties to 45cm apart and dwarf ones to 30cm. Water well after planting.and keep moist until well established. Sunflowers are drought-resistant, but they'll grow better if you provide water from the time the flowers begin to develop until the heads fully mature.
