Because with our tips on planting, caring for and propagating, the poinsettia enchants us all year round.

Poinsettia: origin and characteristics

The poinsettia is native to Central and South America, where it grows as a shrub up to four meters high with a woody trunk. Originally, the natural forms of the poinsettia did not have as much branching as the specimens that can be found on our window sills in winter. The smallest microorganisms, so-called phytoplasms, are responsible for this. Without them, a poinsettia would simply grow single shoots without removing the tips by hand and also only develop a single flower.
Although the poinsettia has become indispensable today, it has only been known to us since 1950 and enchants us during Advent and Christmas. Since then, it has been firmly established as an ornamental plant and is even one of the best-selling indoor plants worldwide.

The leaves of the Christmas star are slightly hairy and alternate. They are pointed at the top and lanceolate or egg-shaped. The lower leaves are dark green, the underside is a little lighter. The high decorative factor of the poinsettia is made up of the so-called bracts, which are not the flowers at all. These are naturally red.
Nowadays, however, poinsettias with cream-colored, pink or pink bracts are also grown. And if that's still not colorful enough, you can even find blue or gold leafed poinsettias. However, these are colored and not grown that way. The actual flowers - in the case of the poinsettia also called Cyathias known - are inconspicuous and greenish-yellow. They bloom from October to January and are surrounded by the colored bracts in a star shape.

Caring for poinsettia

Poinsettias brighten up Advent and bring the Christmas spirit into the house. Unfortunately, most people simply dispose of the plant after the holidays. But that doesn't have to be the case, because the poinsettia is a perennial plant and can even move into the garden bed in summer. With the right care, you can enjoy the beautiful plant for many years. You will learn how to water, fertilize and cut your poinsettia correctly in the next sections.

If the root ball is completely rooted, they can be planted in a larger pot.
