These flowers are also easy to grow. They love sunny spots, handle heat well, and attract bees, butterflies, and birds. Once they settle in, Black-Eyed Susans do not need much care to put on a beautiful show.
In this guide, you’ll learn how to grow Black-Eyed Susans, where to plant them, how to care for them, and how to keep them blooming longer.
What Are Black-Eyed Susans?
Black-Eyed Susans are flowering plants known for their bright yellow petals and dark brown or black centers. Their bold, daisy-like flowers make them one of the most popular summer perennials.
Many Black-Eyed Susans belong to the Rudbeckia plant group. Some types are true perennials, while others may act like short-lived perennials or annuals, depending on the variety and climate.
They work well in sunny gardens because they are tough, colorful, and easy to mix with other flowers. They also look good in both tidy garden beds and relaxed wildflower-style plantings.

Types of Black-Eyed Susans
Black-Eyed Susans come in several types, and they can vary in size, bloom shape, and how long they live.
Perennial Black-Eyed Susans are the best choice if you want flowers that return each year. They work well in sunny beds, borders, and pollinator gardens.
Annual Black-Eyed Susans grow for one season in many gardens. They can still bring strong color, but they may not return after winter.
Some types are short-lived perennials. This means they may come back for a few years, then fade out. Many can self-seed, so new plants may appear nearby.
Best Black-Eyed Susan Varieties to Grow
There are many beautiful Black-Eyed Susan varieties, but a few are especially useful for home gardens.
Goldsturm is one of the most popular varieties. It has golden yellow petals, dark centers, and a tidy shape. It works well in borders, cottage gardens, and pollinator beds.
Indian Summer has large golden flowers that make a bold statement. It is a good choice if you want bigger blooms and strong summer color.
Prairie Sun has bright yellow petals with greenish centers. It gives the garden a fresh look and works well in sunny flower beds.
Cherry Brandy has deep red to burgundy flowers. It adds a richer color than classic yellow types and pairs nicely with ornamental grasses and purple flowers.
Autumn Colors has warm shades of gold, bronze, orange, and red. It is perfect if you want a late-summer garden with a cozy, warm palette.
When and Where to Plant Black-Eyed Susans
Plant Black-Eyed Susans in spring after the last frost. This gives them time to grow strong roots before summer heat arrives.
You can also plant them in early fall if your weather is still mild. Fall planting works best when the plants have enough time to settle before winter.
Choose a sunny spot. Black-Eyed Susans bloom best with at least 6 hours of sunlight each day. More sun usually means stronger stems and more flowers.
They can handle light shade, but too much shade may lead to fewer blooms and weaker growth.
Plant them in soil that drains well. Black-Eyed Susans are tough, but they do not like sitting in soggy soil for too long.
How to Plant Black-Eyed Susans
Start by loosening the soil in your planting area. Remove weeds and break up any hard clumps.
Mix in a little compost if your soil feels poor. Black-Eyed Susans do not need rich soil, but compost can help young plants settle in.
Dig a hole slightly wider than the root ball. Place the plant in the hole at the same depth it was growing in the pot.
Fill the hole with soil and press gently around the roots. Water well after planting.
Space plants about 18 to 24 inches apart, depending on the variety. Larger types may need more room.
Good spacing helps air move around the leaves. This can reduce leaf problems and keep the plants looking healthier.
Black-Eyed Susan Care Guide
Black-Eyed Susans are easy-care flowers once they get established. They mainly need sun, well-draining soil, and simple watering.
Give them full sun for the best blooms. If your plants are not flowering well, check how much light they receive each day.
Water new plants regularly for the first few weeks. This helps the roots settle into the soil.
Once established, Black-Eyed Susans can handle some dry weather. Water during long dry spells, but avoid keeping the soil wet all the time.
They do not need heavy fertilizer. Too much feeding can create leafy growth with fewer flowers. A light layer of compost in spring is usually enough.
Mulch around the plants to reduce weeds and help the soil hold moisture. Keep the mulch away from the crown so the base of the plant does not stay too wet.
Most Black-Eyed Susans do not need staking. If they flop, they may be growing in too much shade, too much water, or very rich soil.
How to Keep Black-Eyed Susans Blooming Longer
Black-Eyed Susans naturally bloom for a long time, but simple care can help them look better.
Deadhead faded flowers during the growing season. This keeps the plant neat and can encourage more blooms.
Cut the old flower stem back to a healthy set of leaves. Use clean garden snips for a tidy cut.
Do not overwater. These plants usually bloom better when the soil drains well.
Give them enough sun. A sunny spot is one of the easiest ways to get more flowers.
Later in the season, you can stop deadheading and leave some seed heads on the plant. Birds may visit the dried seed heads in fall and winter.
Should You Deadhead Black-Eyed Susans?
Yes, you can deadhead Black-Eyed Susans if you want a cleaner look and more blooms.
Deadheading is especially helpful during summer when the plant is still making new flowers. Removing spent blooms keeps the garden looking fresh.
At the end of the season, you can leave some flowers in place. The seed heads add texture and may feed birds.
A good method is to deadhead early in the season and leave some late blooms for wildlife.
Common Black-Eyed Susan Problems
Black-Eyed Susans are tough plants, but they can still have a few problems.
If your plants are not blooming, they may not be getting enough sun. Move them to a brighter spot if possible. Too much fertilizer can also cause lots of leaves with fewer flowers.
If the leaves turn yellow, check the soil. Yellow leaves can happen from too much water, poor drainage, or plant stress.
If your Black-Eyed Susans are flopping, they may be in too much shade or rich soil. Give them full sun and avoid heavy feeding.
Powdery mildew can show up as a white dusty coating on leaves. It often appears when plants are crowded or airflow is poor. Space plants well and water near the soil.
Leaf spots can also happen, especially in humid weather. Remove badly affected leaves and avoid overhead watering.
Aphids, slugs, and Japanese beetles may sometimes bother the plants. Check leaves and flowers often so you can catch problems early.
Are Black-Eyed Susans Deer Resistant?
Black-Eyed Susans are usually deer resistant, but they are not deer-proof.
Deer often avoid them because the leaves and stems are a little rough. Still, hungry deer may nibble almost any plant.
If deer visit your garden often, plant Black-Eyed Susans with other deer-resistant perennials like salvia, lavender, yarrow, catmint, coneflower, and ornamental grasses.
Are Black-Eyed Susans Good for Pollinators?
Yes, Black-Eyed Susans are great for pollinators. Bees and butterflies often visit the bright flowers.
The open flower shape makes it easy for pollinators to reach the center. Planting them in groups can make them even more useful.
Later in the season, birds may feed from the seed heads if you leave some flowers standing.
Best Companion Plants for Black-Eyed Susans
Black-Eyed Susans pair beautifully with many sun-loving perennials.
Salvia looks lovely beside Black-Eyed Susans because the purple flower spikes contrast with the golden blooms.
Coneflowers create a relaxed summer garden look and attract many of the same pollinators.
Yarrow adds flat flower clusters that bring a different shape to the planting bed.
Lavender works well in sunny, well-draining soil and adds fragrance.
Catmint creates a soft purple-blue edge around the bold yellow flowers.
Coreopsis adds more cheerful yellow color and a light, airy feel.
Bee balm brings bright color and attracts hummingbirds and butterflies.
Ornamental grasses add movement, height, and texture behind Black-Eyed Susans.
How to Use Black-Eyed Susans in Garden Design
Black-Eyed Susans are perfect for sunny flower borders. Their warm yellow blooms make the garden feel bright and full.
In cottage gardens, they create a relaxed and cheerful look. Mix them with coneflowers, salvia, daisies, lavender, and catmint for a soft layered bed.
In pollinator gardens, plant them in groups of three or more. Larger groups are easier for bees and butterflies to find.
They also work well in natural-style gardens and meadow plantings. Their simple flower shape blends beautifully with grasses and wildflowers.
You can grow compact varieties in containers. Choose a pot with drainage holes and place it in full sun.
Black-Eyed Susans also make nice cut flowers. Cut them when the blooms are open and place them in fresh water.
Black-Eyed Susan vs Coneflower
Black-Eyed Susans and coneflowers are both popular sunny perennials, but they are different plants.
Black-Eyed Susans usually have golden yellow petals and dark centers. They bring a warm, sunny look to the garden.
Coneflowers often have raised cone-shaped centers and petals that may droop slightly. They come in more colors, including purple, pink, white, orange, and red.
Both plants are easy to grow, and they look beautiful together.
Black-Eyed Susan vs Rudbeckia
Black-Eyed Susan is the common name, and Rudbeckia is the plant group name.
When you see Rudbeckia on a plant tag, it usually means a type of Black-Eyed Susan or a close relative.
Gardeners often use both names, but Black-Eyed Susan is the name most beginners recognize.
How to Propagate Black-Eyed Susans
You can grow more Black-Eyed Susans from seed or division.
Seeds are easy to collect once the flower heads dry. Let the seed heads turn brown, then collect the seeds and store them in a dry place.
Some plants may also self-seed in the garden. This means new plants can appear near the original plant.
You can divide mature perennial Black-Eyed Susans every few years. Dig up the clump in spring or fall, split it into smaller sections, and replant the healthiest pieces.
Division can help older plants stay full and strong.
