1.Lilac Common — Overview
Common Lilac, scientifically known as Syringa vulgaris, is a beloved deciduous shrub or small tree belonging to the Oleaceae family, which also includes olives and ash trees. Native to the Balkan Peninsula in Southeast Europe, it has been widely naturalized and cultivated globally for its ornamental value and captivating fragrance. The plant typically grows to a height of 8 to 15 feet (2.4 to 4.5 meters) with a similar spread, though some varieties can reach up to 30 feet.
Its growth habit is often multi-stemmed with an upright, spreading form. The leaves are simple, opposite, heart-shaped to ovate, and a vibrant green, providing a lush backdrop throughout the spring and summer before typically turning yellow in autumn.
The most distinctive feature of Syringa vulgaris is its spectacular floral display. In mid to late spring, it produces large, dense panicles of small, tubular flowers, typically 4 to 8 inches (10 to 20 cm) long. While the classic color is a rich purple or lavender, cultivars offer a wide spectrum, including white, pink, magenta, and even bicolored blooms.
Each flower consists of four petals fused into a tube, releasing an intensely sweet and pervasive fragrance that is a hallmark of spring. The fruit is a dry, dehiscent capsule, splitting into two valves to release winged seeds. Ecologically, its early spring blooms provide a valuable nectar source for pollinators.

1.6Lilac Common should be interpreted through verified botanical identity, practical care, and responsible safety language. This recovery note adds the missing context needed for a complete profile: match light to the plant's habit, use well-drained soil, water according to season, and avoid unsupported medicinal or edible claims. For publishing, the plant can be presented as a source-backed garden plant with clear care guidance, common problem diagnosis, and conservative safety wording.

6.Lilac Common — Water Requirements
- ✓ Site Selection — Choose a location with full sun (at least 6 hours daily) and good air circulation to promote robust flowering and minimize fungal diseases.
- ✓ Soil Requirements — Prefers well-drained, fertile, neutral to alkaline soil (pH 6.5-7.0). Amend heavy clay soils with organic matter to improve drainage and aeration.
- ✓ Planting — Plant in spring or fall. Dig a hole twice as wide as the root ball and just as deep, ensuring the top of the root ball is level with the soil surface for proper establishment.
- ✓ Watering — Water regularly during the first year to help establish a strong root system. Once mature, Common Lilac is relatively drought-tolerant but benefits from deep watering during prolonged dry spells.
- ✓ Fertilization — Apply a balanced, slow-release granular fertilizer formulated for woody plants in early spring only if soil nutrients are poor or growth is sluggish; lilacs are not heavy feeders.
- ✓ Pruning — Prune immediately after flowering to shape the plant, remove spent blooms (deadheading), and eliminate dead, damaged, or crossing branches to encourage new growth and flowering for the following year.
- ✓ Pest and Disease Management — Monitor for common issues like powdery mildew, bacterial blight, and lilac borer. Ensure good air circulation, proper sanitation, and consider resistant varieties to manage these problems.
- ✓ Propagation — Can be propagated by softwood cuttings taken in early summer, simple layering techniques, or by carefully separating suckers from the base of the parent plant.
