There are several types of lilac flowers, each with its own distinctive characteristics. Common lilacs (Syringa vulgaris) are probably the best known, with clusters of small, fragrant flowers that can range in color from light lilac to deep purple. Persian lilacs (Syringa persica) have smaller flowers and a less intense aroma but are appreciated for their hardiness and ease of cultivation. Another popular variety is the Japanese lilac (Syringa reticulata), which produces large panicles of white or creamy flowers and is known for its large size and ornamental appeal. Each type of lilac offers a unique visual and olfactory experience, allowing for a wide range of options for gardens and floral arrangements.
