What color are poinsettia flowers when read carefully?

The real flowers of the poinsettia, known as cyathia, are a cluster of little yellow blossoms surrounded by multicolor bracts. The colors of the bracts and their arrangement around the flower indicate what kind of cell division is taking place in the plant's tissue that produces new cells for the expanding root system. Red, green, or blue are the most common colors used in decorating trees and shrubs for the holidays.

The colorful boughs are produced by petioles (the thin stalks that connect the leaves to the stem) that have grown longer than usual. As you can see in the picture below, these petioles are covered with small red berries called pyrenes that will turn into more leaves if they fall off. The tree is trying to tell us that growth is good and reproduction is important so it produces more branches than it can support so it won't collapse under its own weight.

Also, look closer at the picture below. You should be able to see three black spots on each berry. These are ovules (female reproductive organs) that will eventually become seeds. When pollinated by insects, the ovules will develop into fruit.

What does a poinsettia flower look like?

The brilliant petals of poinsettias, which appear to be flowers, are actually a clump of the plant's top leaves, known as bracts. Poinsettia blooms are tiny, green or yellow, and grow in the heart of each leaf bundle inconspicuously. Poinsettias are grown as indoor plants in colder climates. They require constant moisture but not much else besides that. The seeds from poinsettias are also called Christmas trees because they look like decorative Christmas trees.

Poinsettias originated in Mexico and Central America and were brought to America by Spanish colonists. Today, they are grown throughout the world for sale in shops and supermarkets.

A poinsettia flower is composed of four petals, two large outer ones and two smaller inner ones. The entire flower is surrounded by hundreds of stamens (male reproductive organs) and carpel (female reproductive organ). When pollen from the stamens is deposited on the stigma of a pistil, it can fertilize the ovules inside the carpel. From these fertilized ovules, seed pods will form which contain up to 100 small red berries called achenes. These are the seeds that will fall off the plant when the pod breaks open due to mechanical stress or when the seeds germinate at soil level.

Are white poinsettias natural?

The colored leafy sections are really bracts, or modified leaves, that alter color as the plant's flowers form. Poinsettias are available in over 100 different hues, ranging from red, salmon, and apricot to yellow, cream, and white (but not blue—these are designer colors created with dyes). The more colorful the bract, the closer it is related to a flower. Cream-colored bracts resemble miniature roses. Yellow ones look like sunflowers.

Although they are grown for their decorative value, poinsettias are useful plants that add color and form to homes during the holiday season. They also attract attention from birds, who eat the poisonous berries for the vitamins they contain. This is why all poinsettia plants should be removed from the garden after Christmas.

White poinsettias are natural species that have been selected for increased blooming rates. Like other members of the genus, they have large showy flowers with petals that fall off one by one. But unlike most other varieties, their flowering period is much shorter (10-12 weeks instead of 20-25) so growers can get a second crop from the same plant. White poinsettias usually bloom earlier than other types and are ready to harvest before they lose all of their blossoms.

White poinsettias are difficult to find in nurseries due to their small size.

What type of leaf does a poinsettia have?

The poinsettia, a well-known Christmas decorative, is a deciduous shrub with big, alternating leaves that may or may not have teeth on the margin. During the Christmas season, the cup-shaped yellow "flowers" bloom and cluster above spectacular red, pink, or white foliage bracts. The poinsettia gets its name from Joel Poinsett, an American minister who brought the first plants to Washington from Mexico in 1882.

Poinsettias belong to the cactus family (Cactaceae). They are native to central Mexico but were soon cultivated elsewhere for sale as holiday decorations. Today, many people assume that because the plant is called a poinsettia that it must be related to potatoes or peas. This is not true: potatoes and peas are members of the potato family (Solanaceae), which is distinct from the cactus family (Cactaceae).

Poinsettias get their name from Joel Poinsett, an American minister who brought the first plants to Washington from Mexico in 1882. At the time, these plants were given the scientific name Echinopsis purpurea, but this was later changed to Euphorbia pulcherrima when scientists discovered they were not actually cacti after all.

Euphorbia is a large genus of about 300 species of herbaceous plants mostly distributed in the tropics and subtropics. About half of them are found in Europe.
