Where Is the Black Eyed Susan Commonly Found?

If you like sunshine yellow or brilliant orange open-faced flowers standing proudly above their green foliage from mid-summer to fall, the black-eyed Susan (Rudbeckia hirta) may be for you. The brightly-colored native American flower sports a domed, black button in the center while its golden rays radiate outward as if blown back by a steady breeze.

  1. Perennial or Annual

    • Black-eyed Susans come in both annual and short-lived perennial varieties — although, in truth, many of them are biennial. The annual varieties tend to be shorter, between 8 inches to 2 feet high, while the perennial types of black-eyed Susan often reach 3 feet, or more, in height with some varieties standing 10 feet tall. Most black-eyed Susan varieties thrive in U.S. Department of Agriculture plant hardiness zones 4 through 8 although some varieties, including annuals, can be found outside this range. Both the annual varieties and perennials bloom from midsummer to fall frost.

    Native Flowers

    • The black-eyed Susan adds more than interest, color and a long bloom time to gardens. Being native plants, they are also good for native insects, especially bees. The bright black and yellow flowers are an excellent nectar plant for bees of all types, as well as some flies. Eaten by rabbits and deer, black-eyed Susan plants help attract wildlife to your garden.

    Location

    • Black-eyed Susan grows throughout the United states, Canada and even Alaska. You can find these plants in mountainous regions of the U.S., in prairies and open fields. Their long roots make them an integral part of the Midwestern prairie systems because they grow in a wide variety of locations from dry to mesic. The black-eyed Susan is not found in desert areas.

    Colors

    • The yellow halo of color in a black-eyed Susan comes not from normal petals, but from mini ray flowers with one giant petal. That is because these native plants bear composite flowers, meaning the black centers are made up of an aggregation of tiny petal-less flowers surrounded by a corona of one-petal ray flowers. Aside from their well-known bright-yellow ray petals, you can find varieties of black-eyed Susan with tinges of red or brown near the center of the flower. Brown-eyed Susan is a variety of black-eyed Susan with brown buttons instead of black. Some varieties have double the number of ray-petal flowers creating a puffy flower effect.
