Erysimum ‘Jenny Brook’ from Blooms of Bressingham was voted one of the top 12 perennials in the Trial Gardens at the University of Georgia in 2009. It won a Classic City Award, which is given to plants with the highest performance for the longest period of time in the challenging environment of Athens, Ga. Striking multi-colored flowers top this tender, shrubby perennial. And they just keep coming, for months at a time. Purple buds open to peach flowers, maturing through rose back to purple.
