Helianthus angustifolius
Common Names: Swamp Sunflower, Narrow-leaf Sunflower
Swamp Sunflower grows happily in moist, sunny areas. Even though it will grow in water-logged soils better than most sunflowers, it can also tolerate periods of drought too. It fills the wildflower niche between wetland plants and upland species. It is a perennial, so even though it dies back in winter, it will return from its roots in the spring. On occasion, if Swamp Sunflower becomes too tall, you can cut it back in June so it will be bushier and still have blooms in the fall.
Swamp Sunflower has a dark purplish center, yellow petals, reddish-purple stems, and skinny willowy leaves. The flowers are 2-3 inches across - smaller than the other species in the sunflower family. Although it has slightly more petite flowers, Swamp Sunflower will bloom for a more extended period. Butterflies, bees, and other pollinators flock to this valuable nectar source. With all the pollinator action it draws, many seeds are produced. These seeds are a great food source for many kinds of wildlife, from small mammals to many different types of birds. Swamp Sunflowers will be a favorite in your native landscape for you and the wildlife.

Spring Shipping:
Orders are shipped within 10-15 business days. We will email you if there are expected delays.
When you order plants from our nursery, you can expect them to arrive in the best possible condition. Our team carefully packs each order using sturdy, biodegradable packaging materials.
Your plants' appearance may vary depending on the season and their current growth stage. We may cut back the leafy growth of some plants to prepare them for shipment and transplanting.
5 Gallon and Up: Any plant purchased to ship over 5 Gallons will be shipped bare root. This means we will remove the plant from its original pot, remove the soil surrounding the roots, and wrap the roots with a biodegradable plastic bag. This reduces weight and the likelihood of damage during shipping.
Once your plants arrive, it is essential to plant them as soon as possible. This will help them rebound and thrive. If you cannot plant immediately, water regularly and keep the roots off heat-conducting surfaces.
Newly transplanted plants often require more water until their roots are well established. Plan to water them 1-3 times weekly for the first few months.
