A compact and floriferous perennial, Lychnis ‘Petit Henri’ produces fluffy, double white blooms on upright stems throughout summer. The flowers sit above silvery-green foliage, offering a soft, romantic charm to borders, cottage gardens, and wildlife-friendly planting schemes. Despite its delicate appearance, it’s a robust and easy-to-grow variety that keeps blooming from early summer into autumn.

Lychnis ‘Petit Henri’, commonly known as White Campion or Double White Lychnis, is a smaller, more refined cultivar of the traditional Lychnis coronaria, bred for continuous flowering and a more manageable habit.
