RUDBECKIA amplexicaulis (Clasping Coneflower) is a perennial wildflower native to North America. It is a member of the sunflower family (Asteraceae) and is valued for its unique flowers, drought tolerance, and ability to attract pollinators.
Clasping Coneflower is a medium-sized perennial that typically reaches a height of 2 to 4 feet (60 to 120 cm) and has a spread of about 1 to 2 feet (30 to 60 cm). It thrives in full sun and prefers well-drained soil. It has slender, branching stems and leaves that are clasping or partly encircling the stem. The leaves are lance-shaped, toothed, and medium green in color. The foliage adds a pleasing textural element to the plant.
The flowers of Rudbeckia amplexicaulis are distinct and eye-catching. They have prominent dark brown or black central cones surrounded by bright yellow ray florets. The ray florets are elongated, narrow, and slightly drooping. The flowers are pollinator-friendly and attract bees, butterflies, and other beneficial insects.
Clasping Coneflower typically blooms from midsummer to early fall, with the flowering period lasting for several weeks. The long-lasting flowers provide a burst of color and contribute to the beauty of late-season gardens.
Clasping Coneflower is often used in prairie-style plantings, wildflower meadows, or cottage gardens. Its unique flower shape and vibrant color add a touch of charm and natural beauty to the landscape. It can be planted in mass plantings, mixed borders, or as a focal point in a garden bed. Additionally, the flowers can be used as cut flowers in floral arrangements.
Clasping Coneflower, with its distinct flowers and attractive foliage, brings a touch of elegance and natural appeal to gardens and landscapes. Its ability to attract pollinators and its tolerance to drought make it a valuable addition to water-wise and wildlife-friendly gardens.
