As the days grow shorter, the wintry winds of December will bring with them a host of holidays — and holiday plants. Walk into most stores, and you’ll see shelves of poinsettias, holiday cactus and amaryllis among many others geared towards decorating our homes and gifting to our loved ones.

Poinsettia (Euphorbia pulcherrima) is arguably the plant most associated with the holiday season. Whether traditional green with bright red leaves or variations of cream and pink, they provide an impressive display with minimal care. Poinsettia flowers are actually the tiny, yellow blooms at the center of the colorful leaves (called bracts) that we think of as flowers. Those leaves change color in anticipation of blooming.
