Black-eyed susans are long-blooming perennials and one of the most common wildflowers grown. They have daisy-like flower heads and deep brown-purple centers. These flowers can tolerate tough conditions and are good for cut flowers; they are also good for borders or in containers.
§ Plant seeds in moist, well-drained soil in full sun or partial shade.
§ Black-eyed susans grow to be between 1 and 3 feet tall and can spread between 12 to 18 inches, so plant seeds closer to prevent lots of spreading or plant further apart to make a nice border.
§ Check your plants regularly to see if they need watering. Make sure they don’t dry out.
§ Divide your plants every 3 to 4 years to ensure healthy plants and to prevent excessive spreading.
§ Be sure to remove faded/dead flowers to prolong blooming.
§ You can cut back black-eyed susans after they flower and a second, smaller bloom may occur in late fall.
