Welche Temperatur braucht der Weihnachtsstern?
Bei 18 bis 20 Grad Celsius halten die Blüten im Winter deutlich länger als in sehr warmen Räumen. Aber nicht nur gegenüber zu hohen Temperaturen, sondern auch gegenüber Kälte und Zugluft ist der Weihnachtsstern recht empfindlich.
Wie muss man Weihnachtssterne Gießen?
Gießen Sie den Weihnachtsstern erst, wenn sich die Erdoberfläche trocken anfühlt. Verwenden Sie zimmerwarmes, abgestandenes Leitungswasser. Um schädliche Staunässe zu vermeiden, gießen Sie über den Untersetzer oder Übertopf und schütten Sie überschüssiges Wasser nach 20 Minuten weg.
What is the scientific name of Poinsettia?
Poinsettias are part of the Euphorbiaceae or Spurge family. Botanically, the plant is known as Euphorbia pulcherrima. In Nahuatl , the language of the Aztecs, the Poinsettia was called Cuitlaxochitl (from cuitlatl, for residue, and xochitl, for flower), meaning „flower that grows in residues or soil.“
What is Poinsettia sap called?
Poinsettias are part of the Euphorbiaceae or Spurge family. Botanically, the plant is known as Euphorbia pulcherrima. Many plants in the Euphorbiaceae family ooze a milky sap. Some people with latex allergies have had a skin reaction (most likely to the sap) after touching the leaves.
Where do poinsettias get their pollination?
They are grouped within the cyathia (small yellow structures found in the center of each leaf bunch, or false flowers). Nothing is known about pollination in wild poinsettias, though wasps are noted to occasionally visit the cyathia. All flowers in the Euphorbiaceae are unisexual (either male or female only), and they are often very small in size.
Are poinsettia leaves poisonous to humans?
This misconception was spread by a 1919 urban legend of a two-year-old child dying after consuming a poinsettia leaf. While the sap and latex of many plants of the spurge genus are indeed toxic, the poinsettia’s toxicity is relatively mild.
