大花马齿苋

大花马齿苋 ,又叫半支莲、龙须、草杜鹃、金丝杜鹃等,还常叫它“死不了”“太阳花”,是因为人们摘下它那鲜嫩多汁的肉质茎叶,在阳光下曝晒,虽已失水萎蔫也不至于死亡,扦插还能成活。

花朵生于枝顶,途径可达5厘米,有单瓣、重瓣和半重瓣之分。花色丰富,有白、白花红点、淡黄、深黄、大红、深红和紫红等,还有镶嵌数色彩纹者,除了前两种的茎部为绿色外,其余均为浅棕红色。

要是您把几种不同颜色的植株搭配在一起,那么,尽管正午骄阳似火,可是盛开的大花马齿苋,活像一大群淘气的笑脸,会逗得您心花怒放。

大花马齿苋属于马齿苋科马齿苋属。一年生草本,性喜温暖,耐干燥,喜强光,不耐阴,不畏炎热,适应性强,易栽植。生长期间浇水不宜过多.开花期可追薄肥。若同时结合摘心,促生分枝,则花更加茂密。播种或扦插为夏秋花期之后,似瓜皮帽状的荫果成熟,盖裂,散出细小银灰色、状似月牙形的种子。

要注意及时采收,将它留存起来,待到来年春天便又可种植了。多年生直立草本,高15—50厘米,不分枝或少分枝。茎方形,无毛。叶片三角状卵形或卵状披针形,长1—3厘米,宽0.5—1.3厘米,边缘有少数钝齿,两面无毛或背面脉上有短毛;叶柄长1—3毫米。每节2朵花排列成偏侧的总状花序;苞片叶状,渐变小,脉上有毛;花营长2—3毫米;花冠青紫色,长9—13.8毫米,外面密生柔毛;雄蕊2对,不伸出花冠外;花柱顶端2裂。小坚果表面有小瘤状突起,黑色。

花期5—10月,果期6—11月。产阜宁、盐城、南通、南京、镇江、无锡、苏州、上海等地,生长在水田边、溪边和湿草地;分布于江南各省区,及河北、山东、河南、陕西南部。全草入药,清热解毒散疚定痛。治吐血、血血、赤痢,黄疽,咽痛,肺痈,疗疮,瘟病,蛇咬伤等症。也可代益母草治妇女病。半支莲半支莲为马齿苋科一年生肉质草花,原产巴西。其数朵顶生的小花,花瓣重叠,花色和花形美丽鲜艳,它的花朵又有见阳光才绽放的习性,所以又叫太阳花和午时花。

还因其茎富含水分,且保水力惊人,若将它拔出或摘下一段,置阳光下暴晒,或放置许久,看上去已奄奄一息了,但插在土中,稍有湿润,它仍能神奇般地成活,故人们又送了它一个“死不了”的名字。半支莲株高15厘米至20厘米,茎匍匐状或斜生状,叶尖形肉质圆棍状。花色丰富多彩,有深红、紫红、棕红、深黄、淡黄、白色,又有雪青和白底缀以红点等多种变化,而且其叶和茎均带有紫红晕,十分美丽耐看。

近年来又培育出了可全日开花的新品种,可以不受弱光的影响,又耐瘠薄,耐干旱,更加提高了其观赏效果。半支莲生性强健,极易栽培。

它性喜充足的阳光,过阴不易开花,喜肥沃的沙质壤土,耐瘠薄,怕渍水,不耐寒。其繁殖以播种为主,在3月至4月进行,7天可出苗,约60天可见花,7月至9月为盛花期。半支莲株高仅15厘米左右,丛生密集,花繁艳丽,花期又长,是装饰草地、坡地和路边的优良配花,亦宜花坛边缘和花境栽植,盆栽小巧玲珑,可陈列在阳台、窗台、走廊、门前、池边和庭院等多种场所观赏。若让其部分茎叶和花朵垂挂于花盆四周,垂立结合,别有一番意趣。
