Thank you flowers are commonly given in Singapore to show gratitude to another individual. For the longest time, flowers have been used to communicate emotions. Any flower would be loved by your recipient and probably end up on their Instagram account. But, why not formulated a hidden message in the bouquet that you are about to give?
Hydrangeas are often given to people whom you have inconvenienced a lot. You could be a student or a patient in a hospital, wanting to say thank you to the incredibly patient teacher or nurse.
Roses are seen by Singaporeans to represent gratitude too. Pink and yellow roses often do not convey romantic emotions and are perfect to say thank you with. They symbolise appreciation, friendship, and joy.
