rough-leaf hydrangea

Hydrangea aspera is a plant native to East Asia, particularly found in China. While there are traditional uses recorded for other species of hydrangeas, such as Hydrangea macrophylla, no specific traditional medicinal applications have been documented for H. aspera itself. Scientific evidence primarily focuses on the genetic and reproductive biology of this plant. Sequencing genomes of Hydrangea macrophylla cultivars has helped identify genes associated with flower traits, but similar detailed studies are not available for H. aspera. A study examining pollinator sharing and pollen viability found that while there is some positive influence from pollinator interactions on heterospecific pollen transfer, the overall impact is minimal. Pollen viability varied widely between 2.5% to 12.1%, with meiotic abnormalities leading to unbalanced tetrads and supernumerary microspores. Safety concerns for Hydrangea aspera are currently non-existent based on available data; no major issues have been recorded. Similarly, there is no evidence of significant drug interactions involving this plant.
