About the product
Easy to grow F1 Hybrid. One of the darkest maroon, multi-branching sunflowers available in the market.
Ideal for borders and cut flowers. Sow successionally for flowers until frosts. Bees love the plentiful nectar.Vigorous and fast growing plant. A nice-eye catcher and visual protection on fences.
They are used for cutting, as dot plants and in groups.
They make excellent cut flowers if gathered just before they are fully open. Alternatively leave them on the plant for the birds to enjoy the seed-heads that follow.
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.
