How many different types of poinsettias are there?

There are over 100 varieties of poinsettias (Euphorbia pulcherrima). Specifically, poinsettias grow naturally as a perennial shrub. But they are known best as cultivated varieties grown as decorative additions to the end-of-the-year holidays. Cultivars (cultivated varieties) will have rather lengthy scientific, Latin or binomial names. Each name will include the poinsettia genus (Euphorbia), the poinsettia specific epithet or species (pulcherrima) and the name of the cultivar, such as Eckespoint 'Enduring Pink.'
