Coneflowers are easy-care plants that provide long-lasting color to a bed or border. Use the Autumn Sun Cutleaf Coneflower in a cottage- or prairie-inspired garden for a bold burst of yellow. Lemon-yellow flowers have broad petals that come to a rounded point and surround a large, dark-brown cone. The flowers are offset by broad, green-lobed foliage. Also known as Rudbeckia laciniata, this plant is native to North America and blooms from mid-summer through fall.
The Autumn Sun Cutleaf Coneflower is a medium-sized plant that stands 4 to 7 feet tall. This plant has rhizomes or thick tuberous-like roots that gradually spread out and fill in an area. Bees and butterflies are drawn to the large blooms, and birds will visit the plants during the fall to eat the seeds. The Autumn Sun Cutleaf Coneflower is a perennial in USDA zones 5 through 9.
Autumn Sun Cutleaf Coneflower Care
Plant the Autumn Sun Cutleaf Coneflower in an area that receives full to partial sun. This beauty needs 4 to 6 hours of daily sunlight. The soil should be moist but well drained. The Autumn Sun Cutleaf Coneflower prefers moist soil and is not drought tolerant like many other coneflowers. Feed this perennial using a balanced fertilizer once during the spring.
Remove spent blooms to encourage more flowers. The Autumn Sun Cutleaf Coneflower can quickly outgrow a space, so give it room to spread, or divide the plant every few years during the fall or spring.
Autumn Sun Cutleaf Coneflower Spacing
The Autumn Sun Cutleaf Coneflower has an upright, clump-forming growth habit. This beauty will reach 5 to 6 inches tall and 3 to 4 inches wide, but it will spread with time. Space plants 4 inches apart when planting.
