The terms “lilac” and “Syringa” are often used interchangeably, but there are some subtle differences between the two. In general, when people refer to “lilac,” they are typically referring to the common lilac, scientifically known as Syringa vulgaris. This is the most well-known and widely cultivated species of lilac.
One of the main differences between lilac and Syringa is that lilac specifically refers to the flowering shrub, while Syringa encompasses various species within the genus. Syringa includes not only Syringa vulgaris, but also other species such as Syringa persica, Syringa reticulata, and Syringa josikaea, among others. Each species may have its own unique characteristics and blooming times.
The common lilac, or Syringa vulgaris, is known for its spectacular display of massed blooms that typically occurs in May. This is a highly anticipated time for lilac enthusiasts, as the air becomes filled with their sweet fragrance and the landscape is adorned with their vibrant colors. The common lilac has been cultivated for centuries, resulting in a vast array of named varieties, each with its own distinct features. Visiting places like the Arnold Arboretum in Boston allows you to witness the diversity of lilac cultivars and appreciate their beauty.
When it comes to differences in appearance, lilacs can vary in size, growth habit, and flower color. Some lilacs are small, compact shrubs, while others can grow into large, spreading bushes. The flowers of lilacs can range from shades of lavender and purple to white, pink, and even yellow. Each cultivar may have its own unique flower shape, size, and scent, adding to the allure of these plants.
In contrast, the term Syringa is broader and encompasses various species that may have different characteristics compared to the common lilac. For example, Syringa persica, also known as Persian lilac, is a smaller shrub with more delicate flowers that bloom earlier in the season. Syringa reticulata, or Japanese tree lilac, is a larger, tree-like species with creamy white flowers that bloom in late spring to early summer. Syringa josikaea, or Hungarian lilac, has reddish-purple flowers and is known for its resistance to powdery mildew.
Lilac is commonly used to refer to the popular Syringa vulgaris, which blooms in May and offers a stunning display of massed bloom. While Syringa encompasses a broader range of lilac species, each with its own unique characteristics and blooming times. The common lilac is just one of the many species within the Syringa genus, and its popularity is due to its exceptional beauty and fragrance. Exploring the world of lilacs through visits to arboretums or personal gardening experiences can provide a deeper appreciation for the diverse and captivating nature of these plants.
