Fun Flower Facts: Black-Eyed Susans (Rudbeckia Hirta)

Scientific Name: Rudbeckia hirta

Most people have seen black-eyed susans before. They are common wildflowers native to North America that can be found growing in gardens, fields and countrysides everywhere.. They are easily recognized, with their dark brown, almost black, centers with bright yellow daisy-like petals. They also have coarse, hairy foliage.

Black eyed susans would look great in any garden or wildflower meadow, adding bright colour and charm to the landscape. Gardeners love these bright yellow flowers because they are so easy to grow, low maintenance and quick growing. They are the perfect flowers for beginners! As well, they are drought and heat resistant—ideal for hot, dry climates. All you would have to do is sow the seeds and leave the rest to nature. They do well in most soil conditions, as long as it’s well-drained. And best of all, these cheerful flowers will reseed after the first season, so you will have flowers next year without having to replant!

The flowers will bloom prolifically between early summer and early fall. Be sure to give them enough space to grow, as they tend to spread and will crowd out other flowers in your garden. In fact, due to its rapid growth, black-eyed susans have been classified as a weed in some places. Divide your plants every 3 to 4 years to ensure healthy plants and to prevent excessive spreading. Deadheading (removing spent flowers) will increase the number of blooms.

As a bonus, black eyed susans will attract butterflies and bees to the garden. It is also a source of food for some small animals. They would be lovely as cut flowers.
