Product Details

The state flower of Maryland has 2"-4" daisy-like flowers with orange-yellow petals. This beautiful, heirloom rudbeckia blooms over a long period--at least 8 weeks; winter seed cones supply food for birds, too. Black-Eyed Susan is a short-lived perennial (USDA zones 3-7), that may come back for a second or third year, but is often treated as an annual. Great cut flower. North American native wildflower; may re-seed itself and is an excellent addition to wildflower areas.

    Really love this cheery wildflower! My favorite part, is in the morning when I go out to the garden about 10 or so male long-horned bees (Melissodes spp.) are asleep all cuddled together around the flower disc having a sleepover. It’s pretty cute, as these bees usually are solitary in nature, but not when sleeping on this rudbeckia apparently! Zone 5, high desert, Central Oregon.

    After my previous review, the rudbeckia will really let you know when they are ready to flower! The native bees love it and are so cute when covered in pollen! No issue growing them what so ever.

    First time growing this variety. Very beautiful, large blooms. My neighbors thought they were sunflowers. Planted the seedlings in October and they wintered over in my Zone 8b garden and bloomed the following late spring/early summer for a long period of time. Makes a great, long lasting cut flower.

    The seedling took a little time to emerge but now they are emerging left and right! I just scattered them over the surface with no special treatment.

    I have always loved Black Eyed Susans and I am always looking for different varieties to try. This one ended up a lot larger than I expected and it commands attention. Stems are stiff and upright, blooms are 4-5" or more across. I really enjoy this flower a lot! I started it indoors, and planted out after frost and I am very pleased with the number of blooms so far and quality of blooms. I recommend growing this variety.
