基本介绍

雪绒花(学名:Leontopodium leontopodioides);又名火绒草。为菊科火绒草属的多年生草本高山植物。火绒草植株高度15-40cm,植株被白色或灰白色绒毛,原产欧洲的高海拔地区,被誉为阿尔卑斯山的名花。奥地利以火绒草作为荣誉和友谊的象征,并将其定为国花。同时也是瑞士的国花。

形态特征

雪绒花为多年生草本高山植物,高15-40cm,基部木质化,但栽培的不论当年生或隔年生均不木质化。全珠被“丁”字毛,毛带银灰色。茎自基部向上分枝,常呈密丛。叶条形或披针形,长1.5-5厘米,宽1.5-5毫米,两端渐窄,全缘。花序伞房状,果期极伸长,花梗丝状,长2-6毫米;萼片长约1.5毫米,外轮的宽于内轮的,外轮的长圆卵形,内轮的窄椭圆形或窄卵状长圆形;花瓣淡紫色或白色,长圆形,长约3毫米,顶端钝圆,基部突然变窄成爪。短角果椭圆形,长3-3.5毫米,无毛或在上半部有稀疏“丁”字毛;果瓣扁压而稍膨胀,中脉清楚;胎座框常为淡紫色,隔膜白色,半透明,无脉;果梗长7-15毫米,斜上升或近水平展开,末端上翘。种子每室1粒,悬垂于子房室顶,长圆形,长约1.5毫米,淡红褐色,遇水有胶粘物质。花期温室栽培的3-4月,露地栽培的6-7月。果期7-10月。

生长习性及分布

喜冷凉,忌炎热,要求阳光充足,稍耐阴,宜疏松土壤,忌涝,较耐干 香雪球旱、瘠薄。

喜欢冷凉气候,忌酷热,耐霜寒。喜欢较干燥的空气环境,阴雨天过长,易受病菌侵染。怕雨淋,晚上保持叶片干燥。最适空气相对湿度为40~60{bf}。

产地分布:雪绒花约有40个种类,分布在亚洲和欧洲的阿尔卑斯山脉一带。这种花在阿尔卑斯山脉中通常生长在海拔1700米以上的地方,由于它只生长在非常少有的岩石地表上,因而极为稀少。近年在中国河北蔚县小五台山,张北县“草原天路”东段草甸发现野生种存在。

主要价值

火绒草是一种珍贵的花卉。她具有花、叶并美的特点,株形小巧玲珑,叶片银灰绚靓,白色花序如雪,朴实大方。同时具有耐干旱、耐贫瘠的优点,又是多年生草本植物,所以特别适用于岩石园栽植或盆栽观赏。

花语及象征意义

雪绒花花语:重要的回忆。

在奥地利,雪绒花象征着勇敢,因为野生的雪绒花生长在环境艰苦的高山上,常人难以得见其美丽容颜,所以见过雪绒花的人都是英雄。

从前,奥地利许多年轻人冒着生命危险,攀上陡峭的山崖,只为摘下一朵雪绒花献给自己的心上人,因为只有雪绒花才能代表为爱牺牲一切的决心。

关于雪绒花,奥地利有许多传说。人们相信雪绒花王可以指引那些采摘者们找到他们寻觅已久的花,但如果谁将花儿连根拔去,这个人将会坠入万丈深渊。

雪绒花又称火绒草,老头草,在欧洲它象征着荣誉和友谊,是著名的高山花卉之一。近年我国也进行了引种,那么你知道雪绒花该如何养殖吗?其养殖又有哪些注意事项?
