Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

DescriptionAfter receiving a multitude of awards, 'American Gold Rush' black-eyed Susan (or Rudbeckia) is the must-have perennial of the season. It's a triple crown winner, and we'll break down why. All-America Selections chose it as the herbaceous perennial winner after a 3-year winter trial, showing no signs of fungus even in wet, humid conditions. The Perennial Plant Association selected it as 2023 Perennial of the Year for its reliable performance and long-lasting flowers. And finally, the National Garden Bureau named the genus Rudbeckia their 2023 Perennial of the Year for its flower power. All the experts agree: this perennial is worth its weight in gold (and more).
As a native perennial, Rudbeckia is easy to grow, heat tolerant, and drought tolerant. Flowers attract pollinators to the garden, and their seedheads are beloved by birds and other wildlife. It's perfectly suited for cottage gardens, cut flower gardens, prairies, or nearly any spot that needs an extra pop of color. Since it's deer and disease-resistant, you can count on long-lasting blooms year after year.DetailsBotanical name: Rudbeckia 'American Gold Rush' Patent #: USPP 28,498 Common name: Black-eyed Susan Zone: 4 - 9 Sun exposure: Sun (> 6 hours sun) to part-sun (4-6 hours sun) Height x width: 22-26" X 40-44" Flower color: Golden yellow Foliage color: Green Season of interest: Late summer through fall Bloom time: Summer, fall Features: Rabbit resistant, native, low flammability, heat tolerant, drought tolerant, deer resistant, container plants, cold tolerant, best sellers, best for beginners Uses: Background, border, cottage gardening, foundation planting, massing, naturalizing, specimen How To GrowSoil: Average, dry to medium, well-draining soil Light: Tolerates light shade, but best in full sun.

Maintenance & pruning: Deadhead to prolong bloom. Rudbeckias don't generally die out in the center and don't require frequent division.
