The common lilac is renowned for its attractive, sweet-scented flowers and lush green foliage. It is a deciduous shrub that typically reaches a height of 8 to 15 feet and a spread of 6 to 12 feet, creating an elegant and eye-catching presence in any landscape. The ‘Wedgwood Blue’ variety specifically boasts stunning pale blue flowers that add a touch of elegance and charm to gardens and outdoor spaces.

Lilac Flower Arrangement

The flowers of the common lilac are arranged in large, open clusters, known as panicles, which create a breathtaking display during the blooming season. These flower clusters are not only visually stunning but also emit a delightful fragrance that attracts pollinators such as bees and butterflies.

Lilac Foliage

The foliage of the common lilac consists of heart-shaped, deep green leaves that provide a beautiful backdrop to the vibrant flowers. The leaves are arranged oppositely along the stems, further enhancing the visual appeal of the plant.



The common lilac is valued for a variety of uses, including:

  • Ornamental Purposes: Its stunning flowers and lush foliage make it a popular choice for ornamental plantings in gardens, parks, and public spaces.
  • Fragrance Production: The flowers are often used in the production of perfumes and essential oils due to their aromatic qualities.
  • Cut Flower Industry: Lilac flowers are often used in floral arrangements and bouquets for their beauty and fragrance.


Proper watering is essential for the health and vigor of common lilac plants. They require consistent moisture, especially during the establishment phase and dry periods. However, it is important to avoid overwatering, as excessive moisture can lead to root rot and other issues.


Common lilacs thrive in full sunlight, requiring at least 6 hours of direct sunlight daily for optimal growth and blooming. Selecting a planting location with ample sunlight is crucial for ensuring the plant’s overall health and abundant flowering.


Fertilizing lilacs is beneficial for promoting healthy growth and abundant flowering. A balanced, slow-release fertilizer formulated for flowering shrubs can be applied in early spring, just before new growth begins. It is important to follow the recommended application rates to prevent over-fertilization, which can be detrimental to the plant.


Lilacs are adaptable to a range of soil types but thrive in well-draining, slightly alkaline soils. Prior to planting, it is advisable to amend the soil with organic matter, such as compost, to improve its texture and fertility. Adequate soil preparation sets the stage for the plant’s long-term health and performance.


Proper pruning is essential for maintaining the shape, vigor, and flowering of common lilac plants. Pruning should be carried out immediately after the blooming period to avoid inadvertently removing the next season’s flower buds. The removal of dead or diseased wood, as well as the regular thinning of older branches, can help rejuvenate the plant and promote new growth.


Common lilacs can be propagated through several methods, including:

  • Softwood Cuttings: Softwood cuttings taken in early summer and placed in a well-draining rooting medium can develop into new plants.
  • Suckers: Lilacs often produce root suckers, which can be carefully separated from the parent plant and replanted to create new individuals.

Container Popularity

While common lilacs are typically grown as large shrubs in garden landscapes, they can also be successfully grown in containers, particularly dwarf or compact varieties. Container-grown lilacs offer the flexibility to be placed on patios, decks, or balconies, providing their stunning flowers and fragrance in spaces where traditional planting in the ground may not be feasible.

Common Diseases

Disease Diagnosis

Common lilacs are susceptible to various diseases, including:

  1. Powdery Mildew: A fungal disease that manifests as a powdery white coating on the leaves and stems.
  2. Bacterial Blight: Characterized by dark, sunken lesions on the leaves and stems, often leading to wilting and dieback.
  3. Phytophthora Root Rot: A soil-borne disease that causes root decay and can lead to the decline of the entire plant.

Common Pests

Lilacs can also fall victim to pest infestations, with insect pests such as:

  1. Lilac Leaf Miners: Small larvae that tunnel within the leaves, causing them to become distorted and discolored.
  2. Aphids: Tiny, sap-sucking insects that can mass on new growth, leading to stunted and distorted leaves.
