  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on May 18, 2018 8:15 PM concerning plant:
    The "so called" Chinese Lilac is not from China. It is better called the Rouen Lilac (Syringa x rothomagensis) as its origin is a chance seedling between the Common Lilac from southeast Europe x the hybrid Persian Lilac (Syringa x persica) of central Asian origin that occurred in Rouen, France in 1777. This must be the Persian Lilac that is occasionally sold by many larger nurseries in the eastern and midwestern US., but is slightly mislabelled by them. It is usually about 8 to 10 feet high with flower clusters to about 6 inches long that are very fragrant and can be used as cut flowers like the Common Lilac, though they don't hold up quite as long in a vase with water as the other. It is not as frequently planted as the Common Lilac. It also suffers from mildew in late summer and fall.
