Panicled Bulrush

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.

Panicled Bulrush is a native perennial sedge that thrives in saturated soils and shallow water. Spreading readily by rhizomes, it quickly forms tall clumps that make it especially valuable for riparian plantings, erosion control, ecological restoration, and naturalization projects.
Its many-branched clusters of small flower heads give the plant its name and add texture to wetland landscapes. In addition to stabilizing shorelines and improving habitat quality, Panicled Bulrush provides food and cover for waterfowl, small mammals, and other wildlife. A cool-season grower, it is most active in spring and fall, slowing or going dormant during the heat of summer.
