Rudbeckia, also known as Black-Eyed Susan, is a common flower that blooms from July to the first frost. These plants are easy to grow and enjoy in the garden or pots. They have long stems and vibrant bronze petals with a dark center, resembling an eye. They can tolerate cold temperatures and are hardy in zones 3-9.
The first step to growing Rudbeckia is to separate the seeds from the spent blooms in the fall. They are small and light brown in color. You can also purchase Rudbeckia seeds if you don’t have the plants in your garden. Plastic containers or pots should be used for planting. The soil must be well-drained and moist. The seeds can be planted on the soil surface and lightly covered with a thin layer of soil.
Rudbeckia is prone to diseases like mildew, so it is important to take notes on the plants throughout the growing months. Aftercare is key for their success.

Black-Eyed Susan Care
Black-Eyed Susans, also known as Rudbeckias, are a common type of flowering plant that can add a pop of color to your garden. If you want to grow these beautiful blooms, here is some information on how to care for them.
First, you need to decide where to plant your Black-Eyed Susans. They prefer full sun but can tolerate some shade. Make sure to space them about 18 to 24 inches apart to give them enough room to grow. They can be grown indoors as well, but they will thrive better outdoors.
When it comes to watering, Black-Eyed Susans need to be watered lightly. They don’t like to be too wet, so make sure the soil is well-drained. Water them deeply once a week, especially during hot and dry periods. You can also use a misting bottle to spray water over the foliage to increase humidity.
Black-Eyed Susans are not too picky when it comes to soil. They can grow in various soil types as long as it is well-drained. You can combine soil with compost or peat moss to improve drainage and provide nutrients.
Temperature is key when it comes to growing Black-Eyed Susans. They prefer temperatures between 65 and 75 degrees Fahrenheit during the day and slightly cooler at night. They can tolerate colder temperatures, down to about 45 degrees Fahrenheit, but if it drops below freezing, they will need protection.
Black-Eyed Susans can be prone to some problems, including powdery mildew and rust. To prevent these issues, make sure to space your plants apart to allow for air circulation. If you do notice any signs of disease, you can treat them with an appropriate fungicide.
Black-Eyed Susans can be grown from seeds or purchased as seedlings. If you are starting from seeds, sow them directly into the garden in the spring, as they need a period of cold treatment to germinate. You can also start them indoors 6 to 8 weeks before the last frost date and transplant them outside when the danger of frost has passed.
Black-Eyed Susans come in various types, including dwarf varieties and double-flowered types. The most common type is Rudbeckia hirta, which has yellow petals with a black center. There are also other colors available, such as orange and brown.
Black-Eyed Susans are known for their long blooming period, which can last throughout the summer and into the fall. Deadheading the flowers, which means removing the spent blooms, can encourage more blooms to come. You can also cut them for bouquets, as they make a fine addition to floral arrangements.
In colder regions, Black-Eyed Susans will die back in the winter, but don’t worry, they will grow back the next spring. It’s a good idea to add a layer of mulch over the plants in the winter to protect them from frost.
So if you want to add a touch of cheerful color to your garden, consider planting Black-Eyed Susans. With the right care, they will reward you with beautiful blooms year after year.
Light
Light plays a crucial role in the growth and development of Rudbeckia plants. Black-eyed Susan plants require full sun to thrive, meaning they need at least six hours of direct sunlight each day. When selecting a location for planting, it is important to choose a spot within your garden that receives ample sunlight throughout the day.
It is important to note that the temperature within the growing space can also affect the growth of Rudbeckia plants. These plants are typically grown as perennials in USDA hardiness zones 3 to 9. They can tolerate a wide range of temperatures, but they thrive in slightly cooler temperatures, between 65 and 75 degrees Fahrenheit (18 to 24 degrees Celsius), during the day and slightly cooler temperatures at night.
Gardeners can start Rudbeckia seeds indoors or directly sow them into the ground after the risk of frost has passed. When starting seeds indoors, it is recommended to use plastic pots or trays with good drainage to prevent damp-off diseases. The seeds should be sown on the surface of the potting soil and lightly covered with soil or vermiculite.
Aftercare is essential for the successful growth of Rudbeckia plants. Once the seeds have germinated and the seedlings have grown to a size where they can be moved, the young plants can be transplanted into individual pots or spaced out in the garden. Dig a hole in the ground that is large enough to accommodate the roots of the plant and gently place the seedling in the hole. Space the plants about 12 to 18 inches apart to give them room to grow.
Rudbeckia plants are known for their stunning flowerheads that resemble velvet. These flowerheads can range in color from yellow to orange to red, and they can grow up to 4 inches (10 cm) in diameter. To ensure a healthy root system, it is important to water the plants regularly, especially during dry periods. However, overwatering can cause root rot, so it is important to find a balance.
Propagating Rudbeckia plants can be done by either dividing the plants or by growing them from seed. Dividing the plants involves carefully digging up the mature plants and separating them into smaller sections, each with its own roots. These divisions can then be planted in a new location or shared with other gardeners. Growing Rudbeckia plants from seed is a more time-consuming process but allows for a larger number of plants.
If you wish to sow Rudbeckia seeds, you can either purchase them from a garden center or collect the seeds from the flowers yourself. To collect the seeds, wait until the flowerheads have completely dried on the plant. Remove the dried flowerheads and rub them between your fingers to release the seeds.
When sowing Rudbeckia seeds, it is recommended to start them indoors about 6 to 8 weeks before the last expected frost date. Fill a pot or tray with potting soil, moisten the soil, and then scatter the seeds on the surface. Lightly press the seeds down into the soil to ensure good contact, but do not cover them with additional soil. Place the pot or tray in a warm location that receives indirect light.
Throughout the growing season, it is important to keep the Rudbeckia plants well watered and to feed them with a balanced fertilizer. This will help them to grow strong and produce healthy blooms. As the flowers begin to fade, it is recommended to deadhead them to encourage continued blooming. Be sure to stay updated on the specific care requirements of the Rudbeckia variety you are growing, as some types may have additional needs or preferences.
