Rudbeckia (Rudbeckia Hirta Autumn Forest) - What a show stopper! Easily grow flower seeds to bring a colorful display to your border, containers, or even in mass groupings. Rudbeckia Autumn Forest flowers reach up to five inches across in some phenomenally beautiful autumn shades including yellow and shades of red and mahogany with darker centers. The flowers are great for cutting as they have strong stems that are long enough to arrange nicely in the vase. They grow quickly and bloom heavily from flower seed sown the same year and are drought tolerant plants.
How To Grow Rudbeckia From Seed: Sow Rudbeckia seeds outdoors in the spring after the danger of frost has passed. Prepare soil by loosening the top 1 - 2 inches and removing any weeds. Sow the seeds into the loosened soil and rake in. Walk over the area to gently press the flower seeds into the soil. Keep the flower seeds moist until germination. The plants transplant well and should be spaced 12 - 18 inches apart. They form a clump that will reach 12 inches in width or more. Rudbeckia Flower Care: Deadheading prolongs the bloom season, but they will re-seed themselves readily if you leave a few blooms to go to seed. Watch for seedlings in subsequent years.
