Helianthus also known as Sunflower, Swamp sunflower, Thin-leaved sunflower, Maximillian sunflower, Ashy sunflower, Willow-leaved sunflower, Jerusalem artichoke are annuals and perennials, some occurring in dry woodland and prairies, others in damp, swampy habitats in North America, Central America, Peru, and Chile. These usually, tall coarse plants, have creeping or tuberous roots and large leaves. The showy, daisy-like flowerheads are usually 2-4 in. (5-10cm) across, but 12 in. (30cm) or more in the giant annuals and blooms from summer until the first frost. Self seeds easily. Leave the seed heads standing to provide a late fall and winter food source for birds. The flower provides nectar to pollinators from July until the first frost. This is a larval host plant that supports Silvery Checkerspot, Songbirds and several types of specialized bees. No serious problems. Tall plants require support.
