Rudbeckia General Information

Rudbeckia Maxima are also commonly called cabbage leaf coneflower in reference to the basal foliage. Excellent addition to naturalized areas, wildflower meadows, prairies, cottage gardens and borders. Let flower stocks remain after bloom to attract goldfinches-they love the seed. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Rudbeckia Plant Care

Minimal seeding. Prefer moist, fertile well-drained soil. Although drought tolerant, Rudbeckia bloom better with ample moisture. Pinching can produce more compact plants in taller varieties. Can be divided every 4 years in spring. Spent foliage can be cut back to 6" for a flush of new growth.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

100% Guarantee

We offer a 100% unconditional guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
