Hi, I’m Ashley Scott, a gardener with over a decade of experience, and today I’m sharing everything I know about Black-Eyed Susans (Rudbeckia hirta). These cheerful, daisy-like flowers have brightened my garden for years, and with the right care, they’ll thrive in yours too. Let’s dig in!
What Are Black-Eyed Susans?
Scientific Name: Rudbeckia hirta
Common Names: Black-Eyed Susan, Gloriosa Daisy, Brown-Eyed Susan
Black-Eyed Susans are North American native wildflowers known for their golden-yellow petals and dark brown centers. They’re a staple in meadows, cottage gardens, and even roadside plantings. I love their rugged charm—they’re drought-tolerant, attract pollinators, and bloom for months!
Description:
- Height: 1–3 feet tall (depending on variety)
- Colors: Classic yellow with black centers, but newer varieties come in orange, red, and bi-colors.
- Blooming Season: Summer to early fall (June–October).
- Lifespan: Most are short-lived perennials (zones 3–9), but some act as annuals.
How to Grow Black-Eyed Susans
1. Starting from Seeds
Black-Eyed Susan seeds are easy to grow. Here’s how I do it:
- When to Plant: Sow seeds directly in spring after frost or start indoors 6–8 weeks earlier.
- Soil: Well-draining, average fertility (they’re not picky!).
- Sun: Full sun (6+ hours daily) for best blooms. They tolerate partial shade but may get leggy.
Pro Tip: Scatter seeds in fall for natural stratification—they’ll sprout stronger in spring!
2. Choosing the Best Planting Spot
Wondering where to plant Black-Eyed Susans? They thrive in:
- Open gardens, borders, or wildflower meadows.
- Slopes or areas with poor soil (their deep roots prevent erosion).
Avoid soggy spots—they hate wet feet!
Black-Eyed Susan Plant Care
Watering
- Water young plants weekly. Mature ones are drought-resistant—I only water mine during extreme dry spells.
Fertilizing
- Skip the heavy feeders! A light compost layer in spring is plenty.
Pruning & Deadheading
- Deadhead spent blooms to encourage more flowers. Cut stems back to 2 inches after frost for a tidy winter garden.
Pests & Problems
- Aphids: Blast them off with water or use insecticidal soap.
- Powdery Mildew: Improve airflow and avoid overhead watering.
Popular Varieties to Try
- ‘Goldsturm’: A classic perennial with large, long-lasting blooms.
- ‘Cherry Brandy’: Stunning deep red petals (my patio showstopper!).
- Black-Eyed Susan Vine (Thunbergia alata): A tender climber with orange or yellow flowers—perfect for trellises!
Why Are They Called Black-Eyed Susans?
The name likely comes from an 18th-century poem comparing the flower’s dark center to a woman’s “black eye.” Fun fact: Maryland named it their state flower in 1918!
What Do Black-Eyed Susans Symbolize?
These blooms represent justice, resilience, and encouragement. I often gift them to friends starting new ventures—they’re nature’s pep talk!
