During the festive winter season, Poinsettias (scientifically referred to as Euphorbia pulcherrima) have a mesmerizing effect on people with their vibrant mix of red and green leaves. However, what often comes as a surprise is the realization that what we commonly perceive as poinsettia “flowers” are actually distinct formations called cyathia. These fascinating structures comprise of a solitary female flower complemented by numerous male flowers, all surrounded by captivating yellow glands resembling lips.
Poinsettias, a member of the Euphorbia family that consists of diverse succulent and cactus-like plants, showcase unique cyathia that distinguish them from traditional flowers. Instead of the usual petals and sepals, they possess an intriguing cup-shaped structure known as an involucre that surrounds the reproductive components of the plant.
The surrounding petals of a poinsettia plant are vibrant crimson, beautifully decorated with clusters of golden glands running along the edges. These glands produce a delightful sugary nectar that attracts busy bees and wasps, inviting them to pollinate the plant. Nestled within the petals, the male flowers stand on tiny stems and scatter their pollen, hitching a ride on the backs of these diligent insects. Meanwhile, the female flower, positioned at the heart of the petals, stretches out a slender, curved style in anticipation of gathering this precious pollen.
Despite what many people think, the bright red “petals” of poinsettias are actually not petals at all. They are modified leaves known as bracts, which surround the cyathia. These bracts, usually red in color, can also come in white, pink, or variegated varieties, depending on the specific cultivar.
Despite the fact that poinsettias possess a distinct method of reproduction, they are capable of generating viable seeds. Nonetheless, due to their main cultivation purpose being focused on their visual attractiveness, the more prevalent methods of propagation are through the utilization of stem cuttings or tissue culture.
To put it concisely, poinsettias captivate with their unusual reproductive system called cyathia. These intriguing structures comprise a female flower, numerous male blooms, and standout yellow glands. Despite their unorthodox nature, poinsettias have the capability to entice pollinators and yield seeds. So, when you come across a poinsettia in the future, pause for a while and marvel at the intricate charm and distinctiveness of its floral design.
