It was born in 2014 as #NationalBoyfriendDay and in Latin America it became the answer to yellow flowers: blue flowers and bouquets made of Hot Wheels cars wrapped in paper and ribbons.

October 3, Boyfriend Day, was born in 2014 as #NationalBoyfriendDay and in Latin America became the answer to yellow flowers: if she gets yellow in September, he gets blue flowers or a bouquet made of Hot Wheels cars. It’s all in the blue flowers guide.

In Argentina, the third Sunday of October is Mother’s Day, in the middle of the southern spring, with roses and lilies. Other dates in the month:

  • October 5: World Teachers’ Day.
  • October 9: the Colombian variant of purple flowers.
  • October 16: Teachers’ Day in Chile.
  • End of October: in Mexico, Day of the Dead altars start going up.

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 autumn arrives and with it chrysanthemums, the last dahlias, asters and autumn roses; hypericum berries add color to bouquets. In Mexico, October is the month of cempasúchil: the fields turn orange and the markets fill with terciopelo (cockscomb) and baby’s breath for the altars. In Argentina, Chile and Uruguay, full spring with roses, lilies, lilacs and stock, just in time for Mother’s Day.

What to give in October

  • Boyfriend Day: blue hydrangeas, blue roses or a mixed blue and white bouquet. On a tight budget, a single blue flower with a Hot Wheels car tied to the stem.
  • Mother’s Day in Argentina: roses, lilies or a spring bouquet with lilacs and stock.
  • For your teacher: a flower or a small plant with a note.
  • For autumn decorating: dahlias, colorful chrysanthemums and branches with reddish leaves.

Tips for the month

Natural blue flowers are scarce: most blue roses are dyed and sell out in the days before the 3rd. Order them in advance or go for hydrangeas, which give lots of volume. If you’re buying cempasúchil for the altar, do it just a few days before so it’s fresh for November 1 and 2.

November is a busy month: All Saints’ Day, the Day of the Dead, purple flowers on the 9th and Men’s Day on the 19th. Download the reminders so you don’t miss any of them.

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.
