|Varying widely in size and character, these tough, sun-tolerant plants need lots of space. They have big, bold flowers and can spread rapidly. They include important seed oil and food crops such as the Common Sunflower and Jerusalem Artichoke, plus several ornamental perennials. Sunflowers are big-leafed, sturdy plants that need full sun and moist soils. Seeds attract birds. Perennial species grow rapidly, forming sizable clumps that can become invasive. Plant in large gardens or parks. Start by division or seed. All bloom in late summer and fall.
This tall Sunflower has many bright yellow double flowers. Cut back stems and leaves after flowering. Hardier than Helianthus angustifolius, the Swamp Sunflower.
