As a gardening and landscaping enthusiast, I can confidently say that not all Rose of Sharon plants spread. While they do have the ability to spread through their seeds, there are ways to control this and even choose non-spreading varieties.
Rose of Sharon plants are known for their prolific seed production. When the flowers fade and go to seed, they can scatter their seeds around the garden, leading to potential spreading. However, this can be easily managed by regularly pinching off the spent blooms before they have a chance to produce seeds. By doing so, you can prevent the plant from spreading and keep it contained in a specific area.
In addition to controlling seed production, there are also many varieties of Rose of Sharon that only produce non-viable seeds. These varieties have been specially bred to prevent spreading through seed dispersal. So, if you are concerned about the plant spreading, you can choose one of these non-viable seed varieties and enjoy the beauty of Rose of Sharon without worrying about its spreading tendencies.
Personally, I have had experience with both spreading and non-spreading varieties of Rose of Sharon in my garden. I found that by regularly deadheading the spent blooms, I was able to prevent spreading and keep the plants nicely contained. However, I also have a non-spreading variety that I planted in a more confined space, and it has been a great choice for that area.
To summarize, while Rose of Sharon plants do have the potential to spread through their seeds, you can easily control this by regularly pinching off spent blooms. Additionally, there are many non-spreading varieties available that only produce non-viable seeds. So, whether you want to prevent spreading or choose a non-spreading variety, there are options available to suit your gardening preferences.
