Thin-leaved Sunflower

Helianthus decapetalus

Elegant perennial native sunflower will tolerate varied tough spots and shade. Helianthus hosts the third most species of caterpillars throughout most of Maine, and several species of bees that specialize on its flowers. Responds well to pruning (to encourage spreading and blooms) and dividing like exotic perennials. Deer tolerant.
