Apologies to all Seed Needs shoppers. At this time we just aren't able to operate sufficiently. We have no choice but to close our online shop until we have successfully relocated. We tried to open up to orders this past weekend (Jan 17th, 2021) but are just not able to keep up with the lack of space and organization. We are not accepting orders at this time and as that you visit to search for a vast majority of our products. We thank you all for your patience through these crazy times. Your continued business means the world to us. Thank you.

Grow a garden filled with Black-Eyed Susan flowers, from freshly harvested Rudbeckia hirta flower seeds. Black-Eyed Susan originates in much of North America and has become one of the most popular flowers over the years. The plants grow to a mature height of roughly 12 to 36 inches tall and form clumps of beautiful golden yellow flowers, accented with deep brown centers. The blooms spread open to a diameter of about 2 or 3 inches wide. The Black-Eyed Susan is popularly chosen to attract beneficial insects to the garden, such as butterflies, bumblebees, ladybugs and even hummingbirds as well.

Categorized as a perennial flowering plant, Rudbeckia will grow the first year from flower seeds and later return the following year from deeply established roots. Black-Eyed Susan will also make a great cut flower for bouquets & floral arrangements. They are often seen in fields, where they grow in large masses and can be used along fences, as a border plant and even in pots and containers. Deadheading the blooms will extend flowering.

Sowing The Seed

Rudbeckia seeds are very easy to establish from flower seeds. They can be sown indoors or directly outdoors. If started indoors, sow in peat pots, 6 to 8 weeks prior to the last frost, at a depth of 1/16” under topsoil. The seeds are sown at a shallow depth because light is required for successful germination. Transplant or direct sow outdoors when the weather is warm and all danger of frost has passed.

Growing Conditions

Rudbeckia plants will enjoy an area that receives full sunlight for the majority of the day, with temperatures of at least 70F. They also prefer a soil that is rich but also well draining as well. For areas with hard compact soil, it is recommended to mix in compost to improve drainage. Water daily with a light water setting so that the soil is kept moist until germination has occurred.

Germination & Growth

Seeds will begin to germinate within 7 to 14 days after sowing. The plants will reach a mature height of around 12 to 36 inches tall. Space plants about 12 to 18 inches apart from one another. Black Eye Susan will attract an array of beneficial insects, such as butterflies and bumblebees. They also make an excellent cut flower and can be used in flower beds, borders & containers.
