General information about Sunflower (Helianthus):
Sunflower (Helianthus) is best known as an annual cut flower but there are luckily also a lot of perennials. It is this last group of hardy plants we offer you in our assortment. The flowers of these species are not as large as those annuals, but you get more than one per plants. They are also goon in the vase. Sunflower is a strong growing, tall and bushy plant which requires plenty of space. Sunflower likes a spot in the sun in well-draining, good and fertile soil. It is good to add some fresh compost annually. Sunflower looks good in a country or natural garden where it will also attract lots of butterflies. For those gardeners who do not like bright yellows, there are also cultivars in cream. Combine Sunflower with tall Asters (Aster), Culver's Root (Veronicastrum), Maiden Grass (Miscanthus) and Plume Poppy (Macleaya).
