  • Care
    Care Information
    Thrives in well-drained, neutral to slightly alkaline soils. Needs good air circulation. Water deeply, regularly in the first growing season to establish an extensive root system. Once established, reduce frequency; increase frequency again before and during spring bloom period. Fertilize in early spring. Prune after flowering.
    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    History:
    'Old Glory' is a selection from a controlled hybridization between Syringa 'Sweet Charity' and Syringa x hyacinthiflora 'Pochohontas, made by Don Egolf in 1978 and released in march 2006. Thoroughly tested throughout most of the eastern United States from Alabama and Mississippi in the south and north to Michigan, Minnesota and Massachusetts. This cultivar has good tolerance to Cercospora blight and Pseudomonas syringae in warmer climates where these two diseases are a problem. A product of the U.S. National Arboretum, which is leading institution in the United States conducting long-term hybridization, testing and evaluation of trees and shrubs. Over 650 named cultivars have been released by the Arboretum to the ornamental nursery and floral industries. (NA 62974; PI641803)
