Helianthus angustifolius
Swamp Sunflower or narrow-leaf Sunflower, Helianthus angustifolius, can grow in moist, sunny areas from southern New York to Florida, west to the Ohio River valley, and south to southern Texas. It can grow in the boggy piney woods of East Texas and the roadside ditches to the harsh salt environment of the Coastal Salt marshes on the Texas Coast. Even though it will grow in water-logged soils better than most sunflowers, don't get the wrong idea. Swamp Sunflower can also tolerate periods of drought too. It is a lovely wildflower filling the niche between wetland plants such as cattails and upland species. The Swamp Sunflower is a perennial like the Maximilian Sunflower, so even though it dies every 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. If planted this spring, it will bloom Sept. - Nov.
Swamp Sunflower has a dark purplish center, reddish-purple stems, and skinny willowy leaves, while Maximilian Sunflower will have yellow-centered flowers and larger leaves. The flowers of Swamp Sunflower are 2-3 inches across and are 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, which more than makes up for the size. With the whole plant covered in golden yellow flowers, some people think it looks like a large flame. Butterflies, bees, and other pollinators flock to this valuable nectar source. With all the pollinator action it draws, many seeds are produced, which is a boon 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 7-10 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.
