Poinsettia - Euphorbia pulcherrima
Since the holiday are approaching, I thought I might show my Euphorbia pulcherrima flowering. While not really a succulent, it is a pretty plant, but it really isn't the flowers that produce the color, instead, the plant produces large, colorful 'bracts,' which are modified leaves. The true flowers are small, and are borne right at the top of the plant above the colorful bracts.
Below is a close up of the true poinsettia flowers. They're not unattractive, but they are minor when compared with the flamboyant bracts. What looks like individual flowers in euphorbias are actually a collection of flowers called a cyathium. Each cyanthium contains a single female flower in the center, surrounded by many males flowers.
The poinsettia is native to Mexico and was brought to the U.S. and popularized by Joel Poinsett, the first U.S. Ambassador to Mexico.
