Masses of vibrant blooms!
A hardy annual, displaying masses of bright, vibrant blooms on bushy, branching plants with fabulous, contrasting silvery foliage.
Superb for borders.
Grow sunflowers in full sun and average soil with good drainage. It is best to directly sow the seeds in the ground in the late spring. Tall plants with few side branches may require staking—sunflowers often fall when subjected to high winds and heavy rain. After flowering and setting seed, these short-lived annuals will die. If you desire continuous summer sunflowers, plant seeds every two weeks in succession from mid-spring to early summer. These outstanding annuals make superb additions to cutting garden or vegetable plots. Children also love them because they are fun to plant and grow. Sunflower heads can also be cut with their seeds intact, dried indoors and brought outside to feed wildlife in winter.
