Round-Leaved Sundew

Nuttall’s Sunflower is a native perennial wildflower known for its bright, golden-yellow blooms. Flowering from mid to late summer, it offers a late-season nectar source for various bees, butterflies, and other pollinators, while the seeds provide a fall food source for birds. The upright growth habit adds structural height and visual variety to your landscape.

Nuttall’s Sunflower can be found growing in moist to wet meadows, prairies, and open spaces. It can spread quickly via underground rhizomes, making it ideal for large-scale plantings. It is well-suited for naturalization, soil stabilization, riparian zones, and wetland restoration projects. If planting in smaller urban yards or gardens, extra care and maintenance will be required to limit its spread.

Round-Leaved Sundew is a native carnivorous plant, easily recognized by its bright green leaves covered in distinctive red, glandular hairs. These hairs secrete a sticky substance that is used to attract, trap, and digest insects. Their carnivorous nature allows them to survive in nutrient-poor, acidic soils where many other plants may struggle to grow.
They produce small white flowers that grow along the top of a slender, leafless stem. They can be found growing in wetlands, most often among sphagnum moss, in consistently moist, acidic soils. It does best in cooler summer climates and is intolerant of shade. Due to its small size, the plant can be difficult to spot in its natural habitat. Round-Leaved Sundew is an indicator of healthy wetland systems and is valued in ecological restoration and conservation projects.
