Hibiscus Moy Grande

Moy Grande Hibiscus

Hibiscus ‘Moy Grande’ is a bold herbaceous perennial valued for its exceptionally large magenta-pink flowers and vigorous growth. It forms a tall, upright clump of lush green foliage that emerges late in spring. In mid to late summer, spectacular tropical-looking blooms—often 10–12 inches across—open in brilliant rosy-magenta tones with a darker red eye, creating a dramatic focal point in the garden. The flowers continue for weeks and attract many pollinators.
