Ruellia squarrosa: The Charming Water Bluebell

Ruellia squarrosa – Water Bluebell

Ruellia squarrosa, commonly known as Water Bluebell or simply Ruellia, is a delightful perennial native to tropical and subtropical regions. Beloved for its trumpet-shaped, lavender-blue flowers that bloom profusely from spring through fall, this plant adds a soft, cottage-garden charm to borders, containers, and moist garden spots. Its lush green foliage forms a neat mound, making it an excellent ground cover or edging plant in warm climates.

Water Bluebell thrives in partial shade to full sun, preferring consistently moist, well-drained soil. It is remarkably adaptable, tolerating brief dry spells once established, and attracts pollinators like butterflies and hummingbirds. In cooler zones, it can be grown as an annual or overwintered indoors. Low-maintenance and resilient, Ruellia squarrosa is a versatile choice for gardeners seeking long-lasting color with minimal effort.
