Upright Prairie Coneflower
Water Arum

Upright Prairie Coneflower is a native perennial wildflower known for its vibrant flowers, which range from golden yellow to dark rust-red with yellow edges. Rising on tall, slender stems, the flowers’ drooping petals surround a central cone. They bloom from midsummer into fall, attracting butterflies, bees, and other pollinators. After blooming, the florets on the cone eventually develop into seeds, which provide a food source for birds.

Its upright growth habit allows it to grow in clusters, creating a striking display. Due to its deep taproot, Upright Prairie Coneflower is drought tolerant, making it well suited to dry areas and xeriscape gardens. Low-maintenance and deer-resistant, this wildflower is a great choice for adding vibrant color and ecological value to any landscape.

Water Arum is a native perennial wetland plant known for its showy white oval sheaths (spathe) that surround a yellow-green, cylindrical flower spike (spadix). It has large, oblong, heart-shaped leaves on stems that rise above the water from shallow, spreading rhizomes. The blossoms are followed in late summer by tiny, pear-shaped fruits that ripen to bright red, adding ornamental interest to wet habitats.

Water Arum provides food for birds and small mammals that eat its berries, and its flowers attract pollinators. It can tolerate cold climates and forms colonies in shallow water and saturated soils. It is well-suited for ecological restoration, riparian planting, naturalisation, and habitat projects in wet and shaded environments.
