The Arnold dogwood (scientific name: Cornus × arnoldiana) is a unique type of dogwood plant. It is a hybrid, which means it was created naturally from two different parent plants. This special dogwood grows in eastern North America. You can find it in places like Ontario, Missouri, Ohio, Pennsylvania, and Massachusetts.

The Arnold dogwood belongs to the Cornus group, also known as the dogwood genus. It is part of the larger plant family called Cornaceae.

How the Arnold Dogwood Was Discovered

The Arnold dogwood came from a natural mix of two other dogwood plants. These are the silky dogwood (Cornus amomum) and the gray dogwood (Cornus racemosa).

Scientists first noticed these interesting new shrubs at the Arnold Arboretum. This is a famous plant research garden. A scientist named Alfred Rehder studied them closely. He was the one who officially described and named this new hybrid plant. The name "Arnold dogwood" honors the Arnold Arboretum where it was found.

Understanding Plant Names

Plants are given scientific names to help scientists around the world identify them. The Arnold dogwood's main scientific name is Cornus × arnoldiana. The "×" symbol means it's a hybrid.

Sometimes, scientists might group plants slightly differently. For example, the Arnold dogwood is usually placed in the Cornus genus. However, some scientists have suggested putting it in a different group called Swida. No matter the exact grouping, its unique hybrid nature remains the same.
