Rudbeckia triloba

Many-flowered Coneflower

USDA Zone: 4-9

Plant number: 1.455.700

This Coneflower is native all over Eastern North America. Plants form a rosette of green leaves the first year, the second year they produce bushy, upright stems that are just loaded with thousands of tiny brown-eyed golden daisies from midsummer on. A self-seeding biennial, ideal for naturalizing. Seedlings that appear may be easily moved in fall or early spring. Removing faded flowers will encourage plants to bloom for longer. Attractive to butterflies. Terrific for cutting.
