What is the Difference Between Lilacs and Lavender?

Lilacs and Lavender are two incredible flowering plants that bring beauty and fragrance to gardens and homes. While they both possess their unique charm, they differ in various aspects, from appearance to growing conditions and even their uses and benefits. 

Appearance and Color

When it comes to appearance, both lilacs and Lavender are quite distinct. Lilacs are deciduous shrubs or small trees that can reach an impressive height of 6 to 15 feet. 

They feature large, heart-shaped leaves and clusters of vibrant, fragrant flowers. The blossoms of lilacs come in a variety of hues, including shades of purple, pink, white, and even yellow.

Lavender, on the other hand, is an evergreen perennial herb with narrow, silvery-green leaves. These Lavender flowers grow in long spikes, showcasing delicate petals in shades of pale purple, deep violet, blue, and even white.


One of the most noticeable differences between lilacs and Lavender is their fragrance. Lilacs have a strong, sweet scent that is often described as intoxicating and nostalgic.

The aroma of lilacs is associated with springtime and can fill the air with a delightful perfume, with some leaning towards a fruity note while others have a more intense floral scent.

In contrast, Lavender emits a delightful, soothing aroma that is widely recognized and cherished. Its fragrance is herbal and calming – a perfect blend of floral, woody, and slightly spicy notes. 

Growing Conditions

Lilacs are hardy plants that thrive in temperate climates and require a good amount of sunlight. They prefer well-drained soil that is slightly alkaline and appreciates proper air circulation. Besides, Lilacs are known for their cold hardiness, making them a favorite in regions with harsh winters. They also require regular pruning to maintain their shape and promote healthy growth.

On the other hand, Lavender is a Mediterranean native and loves sunny, dry climates. It flourishes in well-drained soil with a slightly acidic to neutral pH. Lavender also enjoys good air circulation and is drought-tolerant once established. It’s a great option for those living in warm and sunny regions, as it can handle hot temperatures and sandy soil.

Uses and Benefits

Lilacs are mainly cultivated for their ornamental value and can be found in gardens, parks, and landscapes. Besides, their fragrant blossoms make some excellent cut flowers, filling the entire space with their sweet scents. In fact, in some cultures, lilac flowers are associated with love and romance.

Moving on, Lavender flowers, with their calming aroma, are widely used in aromatherapy, skincare products, soaps, lotions, candles, perfumery, and many more to go. All credit goes to their soothing properties.

Is Lavender in the Lilac Family?

While lavender and lilacs are both beautiful flowering plants, they actually belong to different families. Lavender belongs to the Lamiaceae family, commonly known as the mint family. On the other hand, lilacs belong to the Oleaceae family, known as the Olive family.

Despite not being in the same family, Lavender and lilacs do share some similarities in their beautiful, fragrant flowers. Both plants are renowned for their aromatic blossoms and have been cultivated for centuries for their delightful scents.

Similarities and Differences in Family Characteristics

Families in the plant kingdom are groups of related species that share certain common traits. These traits can include flower structure, leaf shape, growth habits, and other physical or genetic features.

While families may have some similarities, they also exhibit distinctive characteristics that set them apart. For example, in the Lamiaceae family (where Lavender belongs), plants often have square stems, opposite leaves, and flowers with bilateral symmetry. This family includes other popular herbs like mint, rosemary, and basil.

On the other hand, the Oleaceae family (home to lilacs) is known for its woody shrubs and trees. Members of this family typically have simple, opposite leaves and tubular flowers. Besides lilacs, other well-known plants in this family include jasmine, olive trees, and ash trees.

They have a distinct shape, with small, individual florets forming larger, dense flower clusters. The flowers are accompanied by lush green leaves, adding to their overall attractiveness.

On the other hand, Lavender flowers exhibit a slender and elegant appearance. They feature long, narrow flower spikes topped with tiny, fragrant blooms. 

Lavender flowers are predominantly shades of purple or blue, but you can also find varieties with pink or white flowers. The delicate flowers are complemented by silver-gray foliage, which enhances their visual appeal.

Health Benefits

Both lilac and Lavender flowers offer various health benefits, although they differ in terms of applications.

Lilac flowers have traditionally been used in herbal medicine for their antiseptic and anti-inflammatory properties. Infusions and extracts derived from lilac flowers are believed to help alleviate skin conditions like rashes, eczema, and sunburn. Some people also use lilac as a natural remedy for digestive issues and headaches.

In contrast, Lavender has a wide range of health benefits. Its essential oil is commonly used in aromatherapy to promote relaxation, reduce stress, and improve sleep quality.

Lavender oil is also known for its antimicrobial properties and can be used topically to soothe minor skin irritations, such as insect bites or burns. Additionally, Lavender is often included in beauty and personal care products for its soothing effects on the skin.

How to Grow & Maintain Lilacs and Lavender at Home Gardens?

Are you ready to create a captivating oasis in your backyard? Lilacs and Lavender are the perfect companions for your home garden, offering a symphony of colors and aromas. 

Don’t worry if you are a beginner gardener!

From choosing the right soil to pruning techniques, we will walk you through everything you need to know to ensure your lilacs and lavenders thrive and become the stars of your outdoor sanctuary. 

Soil and Climate Requirements

Creating the perfect environment for your lilacs and Lavender is key to their successful growth. Both of these beautiful plants have their own preferences when it comes to soil and climate. 

Here are some important soil and climate requirements to consider:


These delightful shrubs thrive in well-draining soil that is rich in organic matter. They prefer slightly alkaline soil with a pH ranging from 6.0 to 7.0. 

And when it comes to climate, lilacs enjoy full sun exposure for at least six hours a day. They also appreciate a cold winter period to stimulate their blooming potential, making them a great choice for temperate climates.


Lavender is known for its aromatic foliage and splendid purple flowers. To make your Lavender plants happy, you will need well-drained soil with a pH level ranging between 6.5 and 7.5. 

This plant loves the sun, so make sure to find a sunny spot in your garden where it can soak up those rays for at least eight hours a day. It usually thrives in Mediterranean-like climates, but with proper care, it can also adapt well to other regions with similar conditions.

Planting and Care Tips

Now that you know the soil and climate requirements, let’s talk about planting and caring for your lilacs and Lavender:


  • Choosing the right location: Select a spot in your garden that receives full sun and has enough space for your lilac shrubs to grow and spread. Make sure it’s away from other large plants or structures to provide good air circulation.
  • Planting process: Dig a hole that is slightly wider and deeper than the root ball of your lilac shrub. Place the shrub in the hole and backfill it with soil, gently firming it around the base. Water thoroughly after planting.
  • Watering: Lilacs prefer moist soil, so water them regularly, especially during dry spells. Be careful not to overwater, as they don’t like soggy conditions.
  • Mulching: Apply a layer of organic mulch around the base of the shrub to help retain moisture and suppress weed growth. This, in return, will keep the soil temperature more consistent.


  • Choosing the right location: Find a sunny spot in your garden with well-drained soil. If your soil is heavy or clayey, consider adding some sand or gravel to improve drainage.
  • Planting process: Dig a hole slightly larger than the root ball of your Lavender plant. Place the plant in the hole and backfill it with soil, firming it gently. 
  • Watering: While Lavender is drought-tolerant, it still needs watering during its establishment period. Once established, it requires watering only when the soil is dry to a depth of about an inch. Avoid overwatering, as Lavender doesn’t appreciate soggy conditions.

Pruning and Maintenance

Both lilacs and Lavender benefit from proper pruning and maintenance:


  • Pruning after blooming: Prune your lilacs immediately after they finish blooming. This way, you won’t accidentally remove the buds for next year’s flowers. Remove any dead or damaged branches and shape the shrub to maintain its desired size.
  • Deadheading: Remove the spent flower heads after the lilac blooms have faded. This promotes better energy allocation to the plant rather than seed production.


  • Annual pruning: Lavender requires annual pruning to maintain its shape and encourage new growth. After the first year, prune back one-third of the plant’s height in early spring before new growth begins.
  • Deadheading: Remove spent flower stalks to encourage continuous blooming and prevent the plant from putting energy into seed production.

What are Some Popular Lilac and Lavender Varieties?

Their delicate flavor adds a subtle floral essence to salads, beverages, and desserts. Just make sure to use the flowers sparingly and avoid consuming the green parts of the plant, as they can taste bitter.
