A green and white santini chrysanthemum and white daisy Tanacetum bouquet would typically refer to a floral arrangement consisting of a combination of green and white santini chrysanthemums, and white daisy Tanacetums, which are also known as "feverfew" or "bachelor's buttons".

Santini chrysanthemums are a type of small, pom pom-like chrysanthemum that come in a variety of colors, including green and white. They are often used in floral arrangements due to their long-lasting blooms and vibrant colors. The white daisy Tanacetum, on the other hand, is known for its white petals and yellow center, which can create a simple yet charming look.
