With its eye-catching, bullseye-like blooms, Red Pillar® Rose of Sharon turns heads—and attracts hummingbirds—with ease. Each flower combines deep red centers with soft pink petals and creamy white stamens, creating a striking palette that feels right at home in tropical, romantic, or even formal garden settings.
What truly sets Red Pillar® apart is its narrow, upright habit. It grows tall without taking up much ground space, making it an ideal specimen for tight spots or smaller gardens. Use it as a floral focal point, a bold vertical accent, or plant several together for a living screen that’s far more inviting than any fence. Whether used to define a space or set the tone for your garden’s color story, Red Pillar® brings beauty, structure, and a steady stream of pollinators all summer long.
