What Is a Lilac?

The perennial blooming lilac grows on shrubs and comes in various colors, most commonly pinks, purples, and white/off-white. They typically bloom in late spring, with flowers lasting for about three to four weeks. In fact, the common lilac is one of the longest-blooming species in its family. 

Because lilacs naturally thrive as bushes, plotted lilacs (while possible) don’t typically do as well as other plants. Additionally, they might survive indoors, but they likely won’t thrive inside. Thankfully, this plant requires colder temperatures, meaning you don’t need to take them inside during colder months.

Lilac bushes add a gorgeous pop of color to any landscape or property.



Lilacs are deciduous plants that have multiple blooms. The tall shrub grows upright and features green, heart-shaped leaves. When flowering, the many little petals grow together, appearing as a large blossom. They are typically colorful and fragrant, but many lilac bushes come in colors like white and cream as well. Depending on the type of lilac, they can grow up to 12 feet wide and 15 feet tall.

Native Habitat

While lilacs are native to both Europe and Asia (depending on the species), they’ve become a staple for the northeastern regions of the U.S. and Canada. In fact, across New England, they’re an important part of horticultural heritage. As a symbol of summer (blooming in late spring or end of May), these gorgeous flowers are showcased in the landscaping of many beach homes. They also bless the New England communities with a sweet, aromatic fragrance in the air. Lilacs also grow in some western U.S. states.

Growing Tips

Lilacs do best grown outdoors as shrubs in direct sunlight, as this helps them bloom. Experts recommend planting lilac bushes in slightly elevated areas, so they have good drainage. Their flowers typically bloom in late spring, lasting up to a month. 

Lilacs can tolerate below-freezing temperatures, meaning they can survive throughout the winter. In fact, they require cold temperatures to develop their flower buds eventually. During the spring and summer, once it’s time to bloom, they prefer temperatures up to 75 degrees Fahrenheit

In terms of fertilizer, lilacs prefer liberal amounts of a 5-10-5 granular fertilizer. Apply the fertilizer once a year in early spring (before the plant blooms). 

Can Lilacs Be Grown Inside?

Lilacs are best known for growing on shrubs outdoors, and since you can’t plant a bush indoors, it’s hard for them to survive inside. However, it isn’t impossible. If you want to grow a small or dwarf potted lilac plant indoors, you might be able to enjoy its blooms with the right care. Your plant will need lots of direct sunlight (about six hours, at least) and moist soil with a balanced 10-10-10 (NPK) fertilizer.

Hope and Renewal

After a long, cold winter, lilacs bloom with bright-colored flowers in late spring, promising a warm summer ahead. This flower represents hope and renewal, especially after a period of prolonged darkness. Even when we feel there’s no hope left, the lilac reminds us to keep our faith and embrace rebirth/renewal. You can always start again.

Love and Passion

Lilacs represent deep love and romance. In particular, they often pay tribute to old or lost love and embody the mourning we experience when we lose someone we love.
