Black Eyed Susan - Rudbeckia hirta
The Black Eyed Susan has flowers with the black of brown centers and golden petals. They bloom at the end of summer when fall is coming near. They will grow to anywhere between 1 and 3 feet high and are very low maintenance. They are known to attract wildlife and are very drought resistant. They are exceptionally easy to care for.
Not to be confused with so-called "Black-Eyed Susan Vines," true Black-Eyed Susans are perennial wildflowers native to North America and found across the United States and Canada. The name, however, was likely bestowed upon them by English colonists, who called them after the heroine of a poem by Englishman John Gay. The centers of these blooms, despite the plant's name, are dark brown and may have purplish tones as well. In southern areas, these flowers will bloom from early spring until fall, though most parts of North America will see blooms from June to October. They can also tolerate most soils, but prefer moist, well-drained soil with plenty of organic matter. Applying compost to areas where these wildflowers will be planted will result in profuse blooming. In landscaping, they are a low-maintenance option for borders and containers as well as naturalized meadow areas. They attract butterflies and other pollinators, making them an added benefit near fruiting plants, whether edible or ornamental. Because these plants continually grow and spread, dividing clumps every three to four years keeps them healthy and blooming. This is best accomplished in the late fall when the plants have finished blooming, or in the early spring while they're still dormant. The only other maintenance required is regular deadheading to prolong flowering and straightforward winterization. After the leaves and stems die back in the fall, cut them to four inches above the ground and mulch. In the spring, take away excess mulch and enjoy.
