Plant Description

In mid-fall, Helianthus simulans, or tall narrow leaved sunflower, explodes into flower and covers itself with 3 inch bright yellow sunflowers. These persist well into November after hard frosts, which makes it almost our latest flowering plant. (Only the clump form of Green and Gold, Aromatic Aster, and Bleeding Heart still flower later.) A mature 8 foot tall plant in full flower is about as spectacular as they come.

Helianthus simulans has been circulating in the trade as Helianthus angustifolius, and when we first saw it, we thought it must be a giant form or even a tetraploid (genetically, extra well-endowed). But further research has confirmed its true identity to be H. simulans native to the southern coastal plain from Florida to Louisiana and up into Tennessee and Arkansas. It has narrow willowy leaves and easily reaches 8 feet in height. Grow this sunflower in full sun and give it some moisture. Use it as an incredible fall backdrop or in that place where you need to see some color from a distance. You can just about see this in flower from half a mile away!
