The Willow-leaved Sunflower, Helianthus salicifolius, gives the back of the border a light and airy feeling all season long. Its graceful, fine-textured foliage and tall, thin, green stems are attractive even before the bright yellow, 2″ flowers arrive in late summer and bring on the butterflies. This easy-to-grow native is a sturdy clump-former and fits nicely in naturalized plantings, too.
About 70 species make up the important genus of Helianthus, all of them native to the Americas. They brighten summer and fall with masses of yellow, gold, and sometimes white Daisies. We offer perennial varieties that are as tough as they are beautiful.
HOW PLANTS ARE SHIPPED
The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.

Perennial Sunflowers are large plants, 5–8' tall, with 2" single or double, lemon yellow flowers in July–September. All have roughly hairy stems and leaves. Combine with Heliopsis, Rudbeckia, Helenium, Hemerocallis, and Ornamental Grasses. Beautiful in the back of the border or in a meadow.
Helianthus require full sun and grow in average soil. Fertilize seldom as too much will cause more foliar growth and fewer blossoms. Water during dry spells and allow Helianthus plenty of room; divide every 2–3 years. No serious pests or diseases, but mildew can occur in humid regions.
