Origins and peculiarities of poinsettia

The poinsettia (euphorbia pulcherrima) is a tropical plant originally from Mexico which belongs to the euphorbiaceae family. We also name it Christmas star or Advent Star, because it flowers during winter. Unlike many plants cultivated for their flowers, it is the foliage of the poinsettia that makes it special: indeed, its two-tone central leaves are a real pleasure for the eyes, while its flowers are quite negligible.

 
The poinsettia's colorful bracts can take many colors: red and green, pink and green, orange and green, cream and green, speckled with white…, which makes them THE decorative houseplant for the end of the year by excellence! The poinsettia is indeed one of the decorative plants the most offered during the holiday season, and the plants that are found the most on the table runners on Christmas Eve!

Among the most common varieties of poinsettias are poinsettia menorca (red), poinsettia princessia (pink) poinsettia lilo white (white) and poinsettia pink white (pink and white). It can reach up to 80 cm in height in our latitudes, even if in its natural environment this shrub can climb up to 4 m in height!
 

Planting and cultivation of poinsettia


As a tropical plant, poinsettia is mainly grown indoors. In terms of location, the plant appreciates light situations without direct sunlight and warm rooms (between 15 and 20 ° C).

Regarding watering the plant:

  • It is very important to wait until the soil of your poinsettia is dry between two waterings.
  • The plant does not appreciate excess humidity, so be careful never to leave standing water in the cup of your poinsettia.
  • Prefer a moderate water (minimum 20 ° C), because the poinsettia does not like too cold water.
  • After flowering in March, space the watering.
  • Too much water can cause the leaves to turn white and / or fall off, so don't get your hand too heavy when watering!
     

Poinsettia care

The poinsettia is pruned after flowering, when the leaves begin to wilt and fall; this will encourage the appearance of new shoots and improve the next flowering. Keep only 5 to 10 cm of stems.

Repotting takes place during the rest period in spring. Be sure to choose a slightly larger pot, preferably quite heavy because the plant is very light! To help the poinsettia bloom again, place the plant in the dark 12 to 14 hours a day until it recolours, or wrap it in an opaque paper bag for as long.

The poinsettia is propagated by cuttings in the spring. Warning: its sap is toxic, gloves should be worn when handling it!
 

Diseases and pests of poinsettia

Grown as a decorative plant, poinsettia can be attacked:

  • Aphids, which you can get rid of by spraying the leaves with water and black soap.
  • Red spiders, which will not resist an acaricide product.
  • Whiteflies, which feed on the sap of the plant. Fortunately, these do not resist nettle manure.
