Giant Coneflower Rudbeckia maxima 100 Seeds USA Company

Rudbeckia maxima, also known as the giant coneflower or cabbage leaf coneflower, is a striking perennial plant native to the central and southern United States. It is a member of the Asteraceae family, which includes sunflowers and daisies.

This species is known for its large basal leaves, which can grow up to 12 inches (30 cm) wide and resemble those of cabbage plants, hence the common name "cabbage leaf coneflower." The leaves form a rosette at the base of the plant.

In summer, tall flower stalks emerge, reaching heights of up to 7 feet (2 meters), topped with bright yellow, daisy-like flowers with prominent dark brown or black centers. These flowers can reach 3-4 inches (7-10 cm) in diameter and are attractive to pollinators like butterflies and bees.

Rudbeckia maxima is commonly grown in gardens for its dramatic foliage and striking flowers, adding visual interest to perennial borders and naturalistic plantings. It prefers full sun and well-drained soil and is relatively low-maintenance once established.
