  The poinsettia (Euphorbia pulcherrima), also known as the “Christmas plant” or “Mexican flame leaf,” is native to Mexico. In particular, it grows wild on the Pacific slopes of Mexico. The brightly colored portions of the poinsettia--usually red--are not flowers, but leaves. The plant's actual flowers are tiny, and typically are either yellow or green; they grow in the center of each cluster of leaves.

The flowers are white, with highlights and accents in pink. As is characteristic of orchids, the flower has two petals that frame the central bud and curve outward.
  
  

Gentian Sage

• Gentian sage (Salvia patens) thrives in central Mexico and often is cultivated for its blooms, known for their bright shade of blue.

  The Mexican sunflower (Tithonia rotundiflora), native to Mexico and central America, has red and organge blooms that resemble daisies. Leaves and the stem are covered with a thin layer of fuzz. The Mexican sunflower is one of the few plants that can produce two generations in one season. For example, a flower planted in May will bloom and drop seeds by June; those seeds will then germinate and grow into new flowers.
