一品红 Poinsettia

(重定向自Pointsettia)
Euphorbia pulcherrima en Francisco Manuel Blanco, Flora de Filipinas..., Gran edición... , Atlas I, 1880-1883.
Detalle de las hojas.
Detalle de las flores.

一品红(学名:Euphorbia pulcherrima),又名为圣诞花(**称为圣诞红),大戟科大戟属植物,在圣诞节用来摆设的著名红色花卉。大红大绿的叶片相间,外观色彩充满圣诞节的应景气氛,因而称为圣诞红。

那些被人认为是花朵的红色部份其实是叶,而真正的花是在叶束中间的部份。被栽培的品系的叶通常会被制成橙色、浅绿色、奶油色及大理石花纹,要达到这效果,在十月至圣诞节时,它们不可以在晚上被灯光照射。即使是少量灯光照亦会阻止其开“花”。

一品红通常高六十厘米至三米,其深绿色的叶长约七至十六厘米。其最顶层的叶是火红色、红色或白色的,因此经常被误会为花朵。
