Brown Eyed Susan is a favorite native wildflower that will add a touch of country chic to any late-summer garden or landscape.
These low-maintenance perennials are easy to grow and thrive under almost any conditions, making them an excellent choice for novice gardeners. Individual plants will grow to a mature height of two to five feet through the spring and summer and will produce an abundance of one- to two-inch flowers from late summer until the first frost. Each flower will have six to twelve golden yellow petals surrounding a brown cone in a ray-like formation. Cones will appear brown from a distance, but each has a slight purple tint that adds to the visual interest.
The Brown Eyed Susan has an expected spread of twelve to eighteen inches.
Each plant will grow many stems with two- to four-inch deep green alternate leaves that give the mature plant a full and bushy appearance. Hardy from zones three to ten, the Brown Eyed Susan will thrive in both full sun and light shade. These plants appreciate average, moist, well-drained soil, but can tolerate drought and summer heat for extended periods once they are established. Gardeners prize the Brown Eyed Susan for its versatility. It makes an excellent choice for creating thick, perennial borders that attract bees and butterflies.
The self-seeding Brown Eyed Susan will quickly spread if desired; creating sweeping banks of deer and pest-resistant blooms that can promptly naturalize open areas or bring a rustic look to cottage gardens.
Snipping spent flowers will easily prevent any unwanted spread while encouraging more flowers to bloom. Cut flower enthusiasts appreciate the Brown Eyed Susan’s long-lasting and scent-free blooms. Growers can depend on their vibrant yellow color to bring natural beauty to homes, inside and out, throughout the growing season.
