Also known as: pruinosa, pruinosum
A texture and color epithet describing a surface covered in a waxy, powdery white or bluish coating that gives the appearance of having been lightly dusted with frost. Related to glaucus but implies a more pronounced, almost chalky deposit. Appears as pruinosus (masculine), pruinosa (feminine), or pruinosum (neuter).
Etymology
From Latin pruinosus, meaning "covered with hoarfrost," from pruina (hoarfrost, rime).
Example
“Festuca pruinosa (sea fescue) and certain Aloe pruinosa selections have leaves so heavily coated in their waxy bloom that they appear dusted with white powder — exactly the frosted quality the epithet describes.”
