Minfren White Chiffon Rose of Sharon

Hibiscus syriacus 'Minfren'

The Story

Plant Bio

Hibiscus syriacus, or Rose of Sharon, is a hardy, deciduous shrub known for its large, tropical-looking flowers that provide a burst of color in late summer when few other shrubs are blooming. It has an upright, vase-shaped habit.

'Minfren', sold as WHITE CHIFFON, is distinguished by its large, pure white, semi-double flowers with a lacy, anemone-like center. It is sterile or nearly so, which means no messy self-seeding and a longer bloom period.

Uses & Benefits:

White Chiffon provides elegant, pure white blooms in late summer, adding a touch of sophistication to the garden when other plants are fading. Its long blooming season and large flowers make it an exceptional specimen, hedge, or border plant.

This variety's upright, vase-shaped habit makes it suitable for creating privacy screens or living fences. Being nearly sterile, it eliminates the problem of unwanted seedlings that plague other Rose of Sharon varieties, reducing maintenance.

The large flowers are a valuable late-season food source for pollinators, including bees, butterflies, and hummingbirds, helping to support local ecosystems at a critical time of year.
