Hibiscus syriacus ‘Red Heart’ is a vigorous and highly contrasting ornamental shrub, renowned for its large, brilliant white flowers adorned with a distinct dark red heart. This classic variety offers abundant and long-lasting summer blooms, bringing brightness and structure to the garden.

The deciduous dark green foliage perfectly highlights the blooms and supports regular and sustained growth. Highly attractive to pollinators, ‘Red Heart’ is also appreciated for its reliability and longevity. Well-suited to Quebec’s climatic conditions, it prefers a sunny exposure and well-drained soil to fully express its vigor and strong visual impact.
