Autumn Colors Rudbeckia is another great addition to the huge Black-eyed Susan family. True to it’s name, blooms ranging from yellow through gold, orange and bronzy-red create fall color in the heat of summer on dark green foliage.
Rudbeckia are members of the Aster family. They can be grown as annuals, biennials or perennials. As annuals you can change out the many varieties each year and never tire of this species. Biennials can live for two years and then die out, but Rudbeckia tend to re-seed which makes them perennials in that the seedlings will replace the original plant if it dies out.
The North American native is a Pioneer Plant usually found in prairies, plains, meadows and such locations. A Pioneer Plant is a survivor, for example, if a forest burns down, Rudbeckia are usually the first plant to start growing back. They are usually drought resistant once established but can benefit from additional waterings during extreme dry conditions. Soil is not a factor when planting Black-eyed Susan, they can tolerate a wide range of soil types except wet. Make sure that your location drains well so that it’s number one nemesis, powdery mildew, can’t gain a foot-hold. Insects are rarely an issue, however, slugs and snails can destroy seedlings.
