Detail
    虹之玉(Sedum rubrotinctum),不出状态时呈绿色,表皮光亮、无白粉,在阳光充足的条件下转为红褐色。

虹之玉的养护要点:为喜温暖,不耐寒;喜光照,有较强的耐旱性。喜昼夜温差明显的环境,对温度的适应性较强,在10℃至28℃之间均可良好生长;秋冬季节气温降低,光照增强,肉质叶片逐渐变为红色,因此栽培过程中人为降温可提高观赏价值;适应性强,对土壤要求不严。

  冬季室温不宜低于5℃。喜光,整个生长期应使之充分见光。但夏季曝晒会造成叶片日灼,可适当遮光或半日晒,中午应避免烈日直射。虹之玉夏季注意保持通风良好。它们生长缓慢,耐干旱,因此不宜大肥大水,应见干浇水且浇透,而冬季室温较低时则要减少浇水量和次数。虹之玉一般栽培3年后株形开始散乱,因此应提前进行修剪。
