‘Old Glory’ is a selection from a controlled hybridization between
Syringa ‘Sweet Charity’ and Syringa x hyacinthiflora ‘Pocahontas’ made by
Don Egolf in 1978 and released in March 2006. It is a product of the lilac
hybridization program at the U.S. National Arboretum . ‘Old Glory’ was
selected for its abundant fragrant bluish-purple flowers, rounded growth
habit, and disease tolerant foliage. It shows good field tolerance to
Cerco-spora blight and Pseudomonas syringae in warmer climates where these
diseases are a problem.
