To have a Mexican flower bouquet, you can plan one by:
1. The major one consists of the national flower, the Dahlia, to have a centerpiece that defines Mexico.
2. Contrasting bright blooms such as Mexican Sunflowers or marigolds to use as bright colours.
3. The foliage added or highlighting flowers like yucca flowers and asters added to the texture and height.
4. Selecting culturally coded flowers.
It makes such an arrangement more than decorative, it is an ode to the heritage of the flowers of Mexico and their purposes.
