Yellow flowers on March 21: the spring version

From September to March
The yellow flowers trend was born with “Flores amarillas” (Yellow flowers), the song from Floricienta, the 2004 Argentine series whose heroine dreams of someone giving her flowers of that color. In September 2021 TikTok turned it into a tradition to welcome spring in the southern hemisphere, on September 21.
The problem: in Mexico and Central America September isn’t spring, it’s autumn. So many Mexicans adapted the trend to their calendar and started giving yellow flowers on March 21 too, when spring arrives in the northern hemisphere. Same song, same idea, different season.
| Date | What is celebrated and why | Flower | Color | Where |
|---|---|---|---|---|
| every year | Yellow flowers (northern spring) The September 21 trend doubled: with spring arriving in the northern hemisphere, Mexico adopted a second yellow flowers day. Same song, same idea, different season. | Sunflowers, tulips or yellow roses | Yellow | Mexico and Central America, and increasingly Peru |
March 21 in Mexico
In Mexico March 21 was already a special date before the trend. It is the birthday of Benito Juárez (the public holiday moves to the third Monday of March), and many schools celebrate the arrival of spring with parades of children dressed as flowers, butterflies or bees. On top of that, thousands of people visit archaeological sites such as Teotihuacán that day, dressed in white, to “recharge their energy” with the equinox.
The yellow flowers trend fit effortlessly into that springtime mood, and today Mexican florists prepare for March almost as much as for September.
Which yellow flowers to give in March
The advantage of March 21 is that it coincides with the season of several yellow flowers in the northern hemisphere:
- Sunflowers: the stars, just like in September. In March they are greenhouse-grown, so order in advance.
- Yellow tulips: in full season, well priced and very springlike.
- Yellow roses: the most classic and longest-lasting option.
- Mimosa: still available in early March, with its sweet scent.
- Yellow gerberas and daisies: cheerful and inexpensive.
- Daffodils: the flower of spring in Europe; put them in a separate vase if you combine them with other flowers.
What yellow flowers mean in spring
Yellow stands for joy, friendship and new beginnings, and in March that meaning is reinforced by the change of season: giving yellow flowers is wishing that whatever is starting turns out well. That’s why it works equally for a partner, a friend or your mother. You’ll find the details for each color in the meaning of flower colors.
Tips
If you live in Mexico you can celebrate both dates, March and September. Since March sunflowers are greenhouse-grown, order them a few days ahead or go for tulips, which are plentiful in those weeks. And if you don’t want to miss it, use the “Remind me” button: it will alert you three days before.
Remind me 3 days before
Download the reminder and open it with your phone’s calendar: it repeats every year and alerts you three days before, so you have time to order the bouquet.
