Botanical: Syringa vulgaris
Common: Lilac 'Charles Joly'
General Characteristics: Easily grown in average, medium moisture, well-drained soil in full sun. Tolerates light shade, but best bloom is in full sun. Intolerant of full shade. Prefers moist, fertile, organically rich, slightly acidic to slightly alkaline soils with good drainage. Avoid soggy soils. Needs good air circulation. Prune as needed immediately after flowering. To the extent practicable, promptly remove faded flower panicles before seed set. Best grown in cool summer climates. Not recommended for planting in the hot and humid conditions of the deep South in USDA Zones 9-10. Promptly remove root suckers, particularly on grafted plants, to maintain plant appearance and prevent unwanted colonial spread. Propagate by cuttings in spring.
Lilac Characteristics: Syringa vulgaris, commonly known as common lilac, is an upright, multi-stemmed, suckering, deciduous shrub in the olive family that typically matures to 12-16' tall with a spread to 8-12' wide. Numerous cultivars have been introduced over time in both single and double-flowered forms. Cultivars extend the range of available flower colors to include shades of white, cream, rose, magenta, pinkish-purple, lavender, light blue and purple. It is native to open woodlands, rocky hills and scrubby areas in southeastern Europe, but has been widely cultivated throughout Europe (beginning in the late 1500s) and North America (brought over by colonists in the early 1600s). It is particularly noted for its mid to late spring (May) bloom of very fragrant, tubular, 4-lobed, lilac to purple flowers (each to 1/3" long) which bloom in large conical to narrow-pyramidal panicles (to 6-8" long). Flowers give way to loose clusters of smooth, brown, flattened, dehiscent seed capsules (each to 3/4" long) which persist into winter if not removed. Glaucous, opposite, pointed-ovate to heart-shaped leaves (2-5" long) are dark gray-green to blue green. No fall color. Bark is gray to gray-brown.
