What is this shrub?

We call it a Rose of Sharon down here in the south, but others are calling it a hibiscus? I know they are in the same family, but how do we know the difference?

    This is a hibiscus. The Rose of Sharon is also called an althea and grows into a large shrub--almost like a small tree.

    Exactly right Celmore...in Canada we have them as house plants. They will freeze if we leave them outside in the winter. They are beautiful. The Rose of Sharon is a bush...mine are about 7 ft tall and do survive cold Canadian winters. I live in southern Ontario Canada

    In Western BC (Canada), particularly on the west coast of the mainland and the east coast of Vancouver Island, they grow outside in the garden year round and some can get pretty big - up to 15ft. tall!

    The shrub commonly called "Rose of Sharon" here in the U.S. anyway has the Latin name of Hibiscus syriacus. There are other Hibiscus family plants that are also grown as ornamental plants.

    You can tell the difference by the leaves. Rose of Sharon has a leaf with many lobed serrations.
  • This looks like a Hibiscus not a Rose of Sharon- Does it die down each year and then re-emerge? Rose of Sharon is a deciduous shrub. Yes Hibiscus and Rose of Sharon are related.

    It is a Hibiscus. I have been a gardener and floral designer for over 55 years.

    Another way to tell the difference....the leaves on the Rose of Sharon have a lot of notches. The true Hibiscus has a smooth edged leaf like the plant above. Usually the Rose of Sharon bloom is a bit smaller than a Hibiscus, but this can vary, depending on the climate you live in. Yes, they are related, but still different.

    This is a hibiscus, and it looks like the variety named disco belle which I have in my garden. It dies back in winter.

    It's a Hibicus. It's more of a tropical bush. Where Rose of Sharon's blooms are grown tighter and smaller size.
