<i>Dianthus </i>plant named ‘G22090’

Abstract

A new and distinct cultivar of Dianthus plant named G22090 is disclosed, characterized by large flowers with a base color of light pink with a large red-violet eye, and a very distinct star pattern in the same dark red-violet color radiating from the central eye down the petal to the petal tip. Healthy glaucous blue-green foliage exhibits good field tolerance to common Dianthus pathogens. The new variety is a Dianthus, normally used for outdoor ornamental purposes.
