The showy flowers of the Red Heart Rose of Sharon put on an impressive display all summer long. Also known as Hibiscus syriacus, the lovely 5-petaled flowers are 3-4 inches wide and white with red centers. The flowers bloom from early summer into fall. The Red Heart Rose of Sharon reaches 8 to 12 feet tall and 6 to 10 feet wide, so it can easily dominate a landscape.
Create a flowering hedge or add drama to a mixed planting with the Red Heart Rose of Sharon. Butterflies and hummingbirds enjoy the lovely flowers, but this shrub is deer resistant and can be planted in a rural setting. The flowers understandably get all the attention, but the serrated bluish-green foliage gives the plant a full and complete look. Grow this shrub in zones 5 through 8.
Red Heart Rose of Sharon Care
Plant the Red Heart Rose of Sharon in full to partial sun. While this shrub is adaptable, it sets more flowers in full sunlight. Expect the best results when planted in rich, well-drained soil with a neutral to slightly acidic pH. Rich soil supports new growth, but plants in low-quality soil will benefit from an annual fertilizer application in the spring. Rose of Sharon grows well in moist soil, but does not need much supplemental watering at maturity.
The Red Heart Rose of Sharon has an upright growth habit and an excellent natural form, so it doesn’t require much pruning. This plant blooms on new wood. Shape the plant to remove overgrowth or old branches in the late winter or early spring.
Red Heart Rose of Sharon Spacing
Mature Red Heart Rose of Sharon shrubs will grow 6 to 10 feet wide, so space plants 6 to 10 feet apart when creating a hedge or continuous planting. The shrubs should be far enough apart so the branches of neighboring plants barely touch.
