What is the common name for Spiraea japonica?

Spiraea japonica is commonly known as Japanese Spirea. This name reflects its native origins, as it is originally from Japan. Japanese Spirea is widely appreciated in landscaping for its attractive foliage and flowering capabilities, typically displaying clusters of small pink or white flowers in the summer. Recognizing the common name associated with a specific species can help in identifying plant characteristics and informing garden design choices.

The other options refer to different species or variations within the Spiraea genus. For example, Bridal Wreath Spirea refers to Spiraea prunifolia, which is known for its cascading white flowers, while Lance-leaved Spirea, or Spiraea-lanceolata, has distinctly different leaf shapes and flower arrangements. Common Spirea does not refer to one specific species, but rather is a generic term often used for several spiraea varieties. Therefore, recognizing the correct common name is essential for proper identification and understanding of the plant's specific traits.
