This national flower colouring page for Samoa features the Tuila flower. Teuila flowers can vary from lighter shades of pink to bold red shades, with red being the most traditional colour in Samoa - so you might like to choose pink or red shades for this picture?
Fun Fact: There is an annual festival held in late August/early September in honour of the flower. Tuila petals are often used for traditional flower necklaces (known as ula).
