Flower Parts

The red foliage that people believe are the flowers of the plant, are actually modified leaves or colored bracts. The flowers, also known as the cyathia, are small, yellow, or green in color. They are hidden in the center of the leaf bracts.

History

The plant history is very interesting. It originated in Mexico where it grew as a shrub. The Aztecs used poinsettia plants to help control fever, and as an agent of purification. They even made a purple color dye from the bracts.

Soon after the Spanish conquest, the flowers were used in Nativity processions of Franciscan priests. The name is associated with many legends. It is said that once a poor Mexican girl and her brother brought the flower as a gift to baby Jesus. Hence it got the name "Flower of the Holy Night".

Some say, a poor child prayed to Christ child for a gift and the plant grew at his feet at the altar. The flowers are also said to symbolize the Star of Bethlehem. This is due to its red leaves that symbolize the blood of Christ while the white leaves are associated with His purity.

The name of this plant was given in the honor of the former first Ambassador to Mexico, Joel Roberts Poinsett. Impressed by the bright plants, he sent cuttings from Southern Mexico to his home in South Carolina. Soon, in 1828, he began to cultivate them in his greenhouse.

Today, the flowers gross more than 250 million USD in sales during Christmas. In Mexico and Guatemala, this flower is known as the "La Flor de la Nochebuena" (Flower of the Holy Night).

Caring for Poinsettia

You need to plant poinsettia in a pot that allows adequate drainage. There should be a big enough hole in the bottom to allow drainage. You should plant it in a good-quality potting soil. Water the plant till the excess water drains off.

You should add more water after checking for aridity. This means you need to touch the soil with your fingers. If it feels dry, add more water. Remember to water only when the soil is dry. Also, to avoid damage, do not touch the leaves frequently.

The pots should be kept in the house that gets enough sunlight. The plant should receive at least 6 hours of light each day, and the temperature of the room should be about 65 to 70 degrees F. If the room is warm during winters, then you should leave the plant in the coolest room of your house.

The poinsettia bracts are a bright red during late March and April. When the poinsettia plant is not in bloom, you should not forget to fertilize it with a houseplant fertilizer. It is important to note that this plant is not frost resistant.

Flower Arrangements
