Girlfriend Day on August 1 comes from the American National Girlfriend Day and on social media it works as a second Valentine’s Day.

Medellín’s Flower Festival
In early August, Medellín celebrates the Feria de las Flores (Flower Festival), one of the most important festivals in Colombia. Its symbol is the Silleteros Parade: farmers from the rural district of Santa Elena who walk through the city carrying silletas on their backs, huge wooden frames covered in flowers that can weigh dozens of kilos. The tradition recalls the time when silletas were used to carry flowers and produce down from the countryside to the city. It is the best illustration of why Colombia is one of the world’s great flower producers.
Flowers in season in August
| Month | Spain | Mexico and Central America | Argentina, Chile and Uruguay |
|---|---|---|---|
| August | sunflower, dahlia, gladiolus, zinnia, hydrangea, lisianthus | dahlia, gladiolus, tuberose, sunflower, daisy | mimosa (aromo), freesia, daffodil, hyacinth, tulip |
In Colombia, Ecuador and the Andes, the high-altitude climate lets growers produce roses, carnations, chrysanthemums, alstroemerias and hydrangeas all year round: that is why they are two of the world’s largest flower exporters. This table is a guide: the season changes with the area and the year, and greenhouses extend almost all of them.
In Spain it is the month of dahlias, which last until October, and of sunflowers, gladioli, zinnias and lisianthus. In Mexico, dahlias (the national flower), gladioli and tuberoses. In Argentina, Chile and Uruguay winter ends with the aromo in bloom and the first freesias, daffodils and tulips, which herald the September spring.
What to give in August
- Girlfriend Day: pink roses if the relationship is new, red ones if it’s already serious. A single rose with a note also works.
- For a mother in Costa Rica: roses, lilies or carnations.
- For a summer birthday: colorful dahlias, which are spectacular and still rarely seen in bouquets.
Tips for the month
August is the hottest month in the north: buy hardy flowers and change the water every day. Dahlias don’t keep opening once cut, so choose them already open but with the central petals still tight.
And start getting ready for September: September 21 is yellow flowers day and sunflowers sell out. In Colombia, the third Saturday of September is also Amor y Amistad.
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.
