Mimosa Flowers_ An In-Depth Look at Their Meaning, Symbolism, and Cultural Significance



The genus name Acacia stems from the Greek term akakia or “thorny tree.” This, in turn, comes from the word ake, which means “thorn.” Despite their name, mimosa trees don’t actually have thorns.

The species name, dealbata, translates to “covered in white powder.” This is thought to refer to a lichen that commonly grows on the mimosa’s bark, causing the trees to have a silvery appearance. In the plant’s native New South Wales, the trees are called giigandul and they’ve long been prized for their culinary and medicinal uses.

Mimosa Flowers and International Women’s Day

Mimosa flowers took on additional meaning in the mid-20th century when the bright yellow blossoms symbolized International Women’s Day after World War II. But this annual tradition’s roots stretch to a March 8, 1857 strike of female garment workers in New York, which led to the creation of the first worker’s union for women. In 1911, the Triangle Shirtwaist fire killed more than 120 female factory workers.

International Women’s Day was started to commemorate these two events. The connection to the mimosa flower began in Italy in 1946 by one of the country’s first female politicians, Teresa Mattai. Mattai was a vocal critic of the fascist government and a union leader who stood up against anti-Semitism.

At first, International Women’s Day was associated with the violet. But Mattai suggested that the mimosa be the symbol instead, noting that it was a humble flower with the strength and persistence to grow everywhere, thriving even in harsh conditions.

In Italy, the day is known as la Festa Della Donna. On this day, women receive gifts of mimosa flowers as gestures of solidarity. The flowers may be in bouquets or just a simple bud. Often, women take the day off from work and domestic duties to spend time with their female friends and sisters while enjoying a special mimosa cake that’s bright yellow to resemble the namesake flowers.

The flowers are also used as a symbol of the city of Rome. Artists feature mimosa plants in their works, as well.

Today, the flowers represent strength, solidarity, support, admiration, and sympathy. They’re a perfect addition to floral gifts when you want to show someone you care and that you’re thinking of them, as well as for a birthday, congratulations, or milestone accomplishment. And, of course, they’re a must on International Women’s Day, March 8.
