Ever since the Edwardians and Victorians began to gather black flowers, these unusual blooms continue to capture attention because of their dark, striking shades. Because a true black does not exist, these black flower hues are actually the darkest blood red to the deepest purple. As you encounter these peculiar blooms, learn how to identify them so that you have the option to grow these black flowers in your own landscape and enhance your existing garden design.
Record the seasons when you see the black flowers in bloom. Particularly, note whether you see these flowers just one month out of the year or if they stay for the whole spring or summer.
Note the way that the flowers are growing on the plant. For instance, the black prince snapdragon blossoms sprout from a single stem, while the black viola flowers grow on their own stems.
Write down the colors of the flower petals. Some black flowers, such as the coal black pansy, are all black with yellow centers, while the black nemophila (Total Eclipse) is all black with a white outline.
Look for any distinct characteristics that set this flower apart from others. For example, the black coneflower grows a tall, black cone from the stem without any petals and the Whipple's beardtongue grows in a particular tube shape with three petals pointing out from one side.
Access the United States Department of Agriculture (USDA) website to submit your findings and identify your black flower (see Resources). Click the "Advanced Search" link on the left of the page and then select the options in each section that best match your discoveries. For example, scroll to the Morphology/Physiology section to specify information about growing seasons and petal colors. When finished, click the "Display Results" button at the bottom of the page and then click the resulting links until you pinpoint your black flower.
