Black-eyed Susans (Rudbeckia hirta) are annual wildflowers that are often seen growing in open fields and along roadsides. The flowers have a black center with a yellow ring around it and grow on a long stem. The leaves are green and have a hairy texture. Black-eyed Susans typically bloom from early summer to fall. These flowers are native to North America and can be found in many parts of the United States and Canada. They are also commonly known as brown-eyed Susans, black-eyed daisies, and yellow daisies. Black-eyed Susans are not particular about soil type, but they do prefer to grow in full sun. These flowers are drought-tolerant and can often be seen growing in dry, open areas. While black-eyed Susans will grow in most any type of soil, they seem to thrive near water. They are often seen growing along streams and in wet meadows. The flowers are a favorite of bees and butterflies and make excellent cut flowers. Black-eyed Susans are easy to grow and make an excellent addition to any garden.
Rudbeckia hirta is indigenous to North America’s Central and Eastern regions. Apple pie and bumblebee yellow are synonymous with American food. Her dark central cone distinguishes her from other plants, but it is not the reason she is called black-eyed Susan. Black-eyed Susans are Maryland’s state flower. Olaus Rudbeck, a Swiss botanist, inspired the name of this plant. Poor land daisy has also been used in traditional medicine for thousands of years. Boiling and scurving the roots is used to treat colds and intestinal worms.
Giant black-eyed Susan flowers are popular with wildlife because they are bullseyes for native bumblebees. Silvery checkerspot butterfly eggs are primarily produced in the leaves. To reduce swelling, you can use a tincture made from high-proof alcohol (which is infused with herbs). Cold temperatures can cause a variety of diseases to occur in Rudbeckia seeds. The flowers appear to be able to transplant well, and they appear to bloom stronger and healthier than seeds in direct contact with them. Cover the seeds with a layer of soil if you are going to sow directly. Gardeners frequently find that this plant is very hardy and can be grown in almost any situation, including salty soils.
They appear to perform well when they are left alone and unconcerned about what others think. There’s no reason why black-eyed Susans couldn’t be mixed up with other flowers as well. Unless otherwise specified, Rudbeckia bloom from June to September or October. Despite the fact that most deer and rabbits completely disregard the plant, it is common for them to eat anything when they are hungry. Neem oil can help prevent insects from consuming treated plants by preventing them from eating them. A direct sow is preferred over a Black-Eyed Susan seed. The R. hirta, R. fulgida’Goldsturm, and R. Rudbeckia varieties are some of the most popular black-eyed Susan varieties.
Plants in two-gallon pots are available for purchase at a number of greenhouses and garden centers. Black-Eyed Susan is not a fighter, but she is a lover. Ratata is a flower that appears almost anywhere in the United States and can follow you almost anywhere. There are some great pairings for your poor daisy land. Choose African daisy or landscape grasses that complement the black-eyed Susans’ beauty.
Where Do Black-eyed Susans Grow?
The black-eyed Susan grows between 1 and 3 feet tall (though it can grow taller), spreads between 12 and 18 inches, and has a wide range of colors. Plant seeds closer together to prevent spreading or planting further apart to create a lovely border.
In 2008, the National Garden Bureau named Rudbeckia its plant of the year. You can plant the brightly colored flowers in cheerful colors such as lemon-yellow, orange, and gold in the spring, and they will bloom for weeks at a time without much effort. The cone-shaped heads of black-eyed Susans distinguish them from coneflowers. The species of Rudbeckia that live in North America are divided into a variety of types. Biannual or short-lived perennial species are common, but because they self-sow easily, they frequently return from seed dispersals the following fall. Despite being commonly purchased as bedding plants in the spring, black-eyed Susans are very easy to grow from seed. After the seedlings have grown sufficiently, they should be placed on a sunny windowsill or beneath fluorescent plant lights to provide plenty of light.
In mild climates, seeds can be sown directly in the garden and will germinate in two to three weeks. In addition to being drought- and disease-resistant, black-eyed Susans are extremely easy to grow. This plant is part of the Toto® series and has large 2- to 3-inch yellow blooms with chocolate-brown centers. From mid-June to October, the Rudbeckia fulgida ‘Early Gold Bird’ will awaken before the rest of the Susans. It is a well-known back-of-the-border plant that grows to about 5 feet tall. Try some of these eye-catching looks.
Water rudbeckias thoroughly during their first week or two of planting, and again every week or two until they are established. Plants will become yellow in excess of water. In the spring and summer, feed rudbeckias a balanced fertilizer.
Prune rudbeckias before the new growth begins. Remove the spent flowers and any dead foliage.
The Easy-to-grow Black-eyed Susan
Grow a crop of black-eyed Susans in your garden and add color to it with a splash of color. They prefer full sun, but can tolerate some shade as well. Because they can easily spread if not managed properly, it is important to divide them every four to five years. Summer is when they flower the most and come back each year.
Will Black-eyed Susans Grow In Wet Soil?
When ground is too wet and muddy, it is common for black eyed Susans to rot. It is a good idea to divide your Black Eyed Susans every four years in the fall to keep them healthy. Simply remove all but the last section from the ground and divide it into several smaller sections to keep the root system healthy.
Susans (Rudbeckia hirta) grow in almost any part of your garden and will fill almost any hole. These flowers can be grown in a variety of soils, including loam and sand. The maximum height of a black-eyed Susan is 36 inches when it is grown in consistently moist soil. Flowering plants must be planted with soil that has been tilled to a depth of 15 inches. Organic material must be readily available if it is to be used as a nutrient source in a soil. Mulching provides a barrier between heat and cold to black-eyed Susans while also controlling weeds.
These garden flowers have yellow to orange petals and dark center points on the stem and grow 24 inches tall. Despite the fact that the blossoms appear fragile, these perennial plants have a strong root system that allows them to rejuvenate their roots every year. If you want to save the flowers for the winter, you can cut them down to the ground or to the basal growth, depending on where you are in the country. In the spring, the flower stems can be cut back to shape them. During the winter, birds and other wildlife will eat the seeds.
The Best Soil For Black-eyed Susans
The black-eyed Susan (Rudbeckia) is a beautiful flower with many different types of foliage and can grow in a variety of soils, but it prefers moist, well-drained soil. Watering too much causes more problems than watering too little. Organic matter should be added if the soil is too dry to retain moisture. Black-eyed Susans do well in hot, humid summers, but they won’t do well in cold or drought situations.
Do Black-eyed Susan Flowers Spread?
Black-eyed susan flowers are annuals that self-seed readily. The flowers are produced in summer on 2-3 foot tall plants. The plants will often die back in winter, but will re-emerge in spring.
It has a deep brown center that is inspired by their name, and it is a lovely yellow daisy-like flower with a yellow daisy-like bloom. These flowers can grow to heights of 2-3 feet and add drama to borders or form large sweeps in flower beds. Black eyed Susans are known for their ability to spread and grow large plants throughout the growing season. There are times when black eyed Susans will go underground because they are eager to please. When the seed heads have grown, you can cut them off and scatter them in the place you want to see the most blooms. It’s perfectly fine to keep the blooms in place if you’re content with a blanket of these stunning yellow blooms. In the following step, you will need to dig up the roots with a shovel or trowel. After four years or so, the roots of the plants become tangled and matted, which slows their growth. As a result, they will not stop dropping seeds each autumn, which is not to say they will not continue to do so.
While black-eyed Susans prefer full sun, partial shade is acceptable. The best soil for growing them is moist, well-draining soil, but they are also hardy in dry conditions.
A black-eyed Susan can be bred in the spring, or it can be taken stem-bearing stem in the fall and propagated.

How does black eyed susan spread from leg to leg without touching anything? Black-eyed Susans reach a height of 24 to 36 inches and a width of up to 36 inches. If plants are happy, it is possible to spread underground stems and self-sew. Divide clumps every four to five years to keep the spread to a minimum. To self-seed, cut spent blooms in the fall. How often do black eyed Susans grow? In about 100 days, the black eyed Susan plant will spread and bloom.
