As one of the earliest flowers to bloom in spring (via Almanac), lilacs are often seen as a "symbol of fresh starts" and "renewal," according to Florgeous. As such, lilacs tattoos can mark new beginnings and other important milestones in your life. It can also represent the season itself, one of the most beautiful times of the year. Even better, if you or someone close to you were born during spring, a lilac tattoo can be a unique way of celebrating such an occasion. Lilac happens to be the state flower of New Hampshire, too (via State Symbols USA).
In terms of what different colored lilacs can represent, they can denote "feminine feelings such as love, beauty, tenderness, and compassion," according to TattMag. Pink lilacs can symbolize "unrelenting love and passion," whereas purple lilacs can "represent nobility, royalty, and even ambition." This shade can also represent heartbreak, as the feeling "can often appear as purple in the heart chakra," as aura reader Rachelle Terry told MindBodyGreen.
