Herbstonne Black-Eyed Susan

Availability: Out of stock

The Herbstonne Black-Eyed Susan (Rudbeckia 'Herbstonne') is a summer-blooming perennial with a unique green cone that is surrounded by yellow petals! This giant Black-Eyed Susan is the tallest of the Rudbeckia and will grow to impressive heights!

It does not need staking and holds its blooms upon sturdy stems for pollinators to light upon and stand tall in your wildflower bouquets! The 2-3 inch wide, showy, golden-yellow Daisy-like blooms show off from summer until frost!

Cold and heat tolerant, xeric plants grow throughout USDA growing zones 3 to 9, these towering yellow blooms can reach 6 feet high and spread rapidly to cover large areas 2-3 feet wide. In fall, leave the dried perennial blooms standing, so songbirds can enjoy the seeds in the raised cones. The dried blooms catch and sculpt light snowfall for welcome winter interest.

Planting and Application:

This hardy perennial is excellent in borders or naturalized gardens! Herbstonne will be a real eye-catcher! Plant in the back of the border with Buddleias, Joe Pye Weed, and Ornamental Grasses. Blending into wildflower and prairie plantings, Cottage Gardens and is tough enough for Rock Gardens.

Rudbeckia attracts butterflies, especially Monarchs! Feeding pollinators in the crucial late-season months while they prepare for migration and hibernation. They also provide food for birds in the winter once the raised central cones go to seed! Providing you with winter interest too.

Plant in masses with other hardy perennials throughout tricky slopes and sun-drenched hell strips along sidewalks and driveways for a lovely landscape effect! Pollinator gardens are ideal locations for these pollen and nectar-rich blooms!

#ProPlantTips for Care:

Plant in full sun for the best flowering. They need at least six hours of sun a day. Well-drained soil is important, as well. Pay close attention to watering the first season. In-ground plants will become drought-tolerant after the first season. We do recommend that you protect your investment in extended drought by applying supplemental water as needed. These perennials appreciate 3-4 inches of arborist mulch over the root system to further protect your plants.

Leave the perennial tops up overwinter for protection and visual interest. Birds peck at the seeds, too. You can also deadhead the spent flowers if reseeding is an issue. Prune them down in early spring to an inch or two from the ground. Add flowering plant fertilizer or a top-dressing of compost at that time, if desired. Divide clumps once they get too wide in either spring or fall.

  • Widely Adaptable - Any Well-Drained Soil Type
