Is Rose of Sharon a Hibiscus? Exploring the Relationship Between These Two Flowers

Rose of Sharon is a beautiful flowering shrub that is commonly found in gardens and landscapes across the United States. However, there is often confusion about whether or not it is a hibiscus. While the two plants share many similarities, there are also some key differences that set them apart.

Despite its hardiness, Rose of Sharon is still prized for its beautiful flowers, which bloom in a wide range of colors and can add a splash of color to any garden or landscape. Whether you are a seasoned gardener or just starting out, understanding the differences between Rose of Sharon and other types of hibiscus can help you make informed decisions about which plants to include in your outdoor spaces.
