Hello, my name is Red Heart Rose of Sharon. Just like my name suggests, I am best known for my shock of vibrant red that sits at the center of my large white flowers. When I am in full bloom, it looks as though I have an abundance of dainty ruby red hearts nestled into my flowers and foliage. I also have a talent for attracting butterflies and hummingbirds into your garden - but don't worry, the deer leave me alone! I am a little bit of a diva and will require high maintenance, care and upkeep. However, when it comes to growing conditions I am very adaptable, highly tolerant to urban pollution, and will thrive in any soil as long as it is kept moist - I've never met a garden I didn't want to grow in!
