The Black Eyed Susan, also known as the Gloriosa Daisy, is between 12 and 36 inches tall when it reaches its full height. Although it grows well in a sunny garden, it is a hardy flower that will also do well in a partially shady area.
A positive aspect of growing the Black Eye Susan is that it is a hardy flower, and because they are perennials, they will return each year. The Black Eye Susan should be pruned as winter months arrive after the first frost. Dead leaves should be cut off and pruned to just above the healthy green leaves. Give it plenty of mulch, and with no problem, it will safely make it through the cold winter months.
During the summer months, the Black Eye Susan will begin to bloom, and you will have bright yellow or orange flowers, and although the leaves may turn brown, it is best not to remove them. The plant's root system gives it the nutrients needed to continue blooming all season. The blooming season runs from early summer until fall.
The planting season for the Black Eye Susan is between March and May, as long as the soil temperature is at least 70 degrees. It will take a week to a month for the flower to germinate, producing flowers until late September or even later in warmer climates.
The Black Eye Susan is not only a favorite in flower gardens but may also be seen growing alongside the road as a wildflower. The Rudbeckia Hirta may be seen in many areas of the U.S., as it traditionally was found in the western part of the U.S. It adapted as it became a favorite flower in the east. It has earned its name as a symbol of encouragement, possibly because it is a hardy plant that adapted well in many areas of the country.
