Diana Rose of Sharon

Diana Rose of Sharon is a beautiful flowering shrub known for its large, pure white blooms that appear in summer and often continue into fall. Unlike many Rose of Sharon varieties, its flowers do not have a contrasting red center, giving them a clean, bright appearance that stands out against the dark green foliage.

Its naturally upright growth habit makes Diana a strong choice for sunny borders, flowering hedges, privacy plantings, mixed shrub beds, and Southern landscapes that need dependable late-season color. The flowers also attract butterflies, hummingbirds, bees, and other pollinators. Because the shrub can become tall and broad, give it enough room to develop its natural shape without crowding nearby plants or walkways.

Diana Rose of Sharon performs best in full sun to part sun with well-drained soil. It handles Southern heat and humidity well once established, but regular watering is important during the first growing season and during long stretches of hot, dry weather. A two- to three-inch layer of mulch can help the soil hold moisture and keep the roots cooler, but keep mulch a few inches away from the main stems.

Because Diana blooms on new growth, it can be pruned in late winter or early spring if shaping is needed. Remove dead, damaged, or crossing branches first, then lightly shorten the remaining stems to maintain a balanced shape. Avoid severe pruning unless the shrub has become overgrown.
