Iris germanica 'Jesse's Song'
Iris germanica ‘Jesse’s Song’ is a tall bearded iris with a crisp white ground and violet plicata banding. It blooms in midseason and shows best in full sun and well-drained soil. Plants reach about 36 inches and carry clean patterning that reads well in the border. Rebloom has been reported in a few regions, yet it is not universal. Choose this cultivar for classic plicata style and strong show credentials.
