Noteworthy Characteristics

Oenothera is a genus of about 125 species of annuals, biennials and herbaceous perennials mostly from North America with a few species from South America. They are grown from their lovely flowers in shades of yellow, white or pink depending upon the species.

Genus name is unclear but may have come from the Greek words oinos and theras meaning wine-seeker in probable reference to an ancient use of the roots of genus plants in scenting wine.
