飘香藤(学名:Dipladenia sanderi或Mandevilla sanderi)是一种新型藤本植物,又称红皱藤、双腺藤、双喜藤、文藤、红蝉花,原产美洲热带,为夹竹桃科多年生常绿植物。飘香藤的缠绕茎柔软而有韧性,顺着支架盘旋而上,粉红似喇叭的花儿大而直挺,花茎能达到6~8厘米。
飘香藤喜欢温暖湿润的环境,但分枝性不好。飘香藤在开花期间,往往呈现花多于叶的盛况,微风袭来,阵阵扑鼻的清香使人心旷神怡,因此就有了“飘香藤”的雅名。
    • Light exposure: Blooms best in full sun, a minimum of 4 hours of direct sunlight per day.
    • Planting: Plant at same depth of soil as in the pot – in beds arrange plants 20 to 30 cm (8″ to 12″) apart.
    • Height: Grows 30 to 60cm (12″ to 24″) in height.
    • Watering: Allow soil to dry out in between watering. Can tolerate some drought.
    • Temperature tolerance: Can be planted outdoors after frost has passed – protect from frost in the fall, can be overwintered indoors.
    • Fertilizer: Rio plants come pre-fertilized.
    • Deadheading: No deadheading is required, blooms will fade and fall off. Rio dipladenias will keep pushing out fresh blooms without deadheading.
    • Features: Rio blooms attract butterflies and hummingbirds.
    • Overwintering tips: Rio dipladenias may not survive in regions where temperatures drop below 7 degrees C or 45 degrees F in winter. Bring your plants indoors in fall to overwinter them. Place your Rios close to a window that receives all-day sunlight. Make sure the temperature remains above 7 degrees C or 45 F. Dipladenias only need watering when the top 5 cm (2 inches) of soil begin to dry. Some foliage may die, but your Rios should produce new foliage in spring. Rio dipladenias come pre-fertilized but plants that have been over-wintered can be fertilized once in May and once in August, with slow-release 18-6-12 fertilizer. Do not fertilize during winter as dipladenias’ natural rest period lasts from October to April.

光照要求:飘香藤喜欢温暖湿润并且阳光充足的环境,有充足的光照才能保证飘香藤的正常生长,半日照至全日照均可。当然飘香藤也可以放在稍微荫蔽的场所养护。

水肥管理:在飘香藤的养护过程中要做好水肥管理。在浇水上,要控制浇水,不要过涝过干,使植株生长不良。做好水肥管理,能形成发达的根系,飘香藤的生长才会旺盛。在生长期里,可适量追施复合肥3—5次。

温度要求:飘香藤生长的最佳温度为20—30℃之间,最好不要超过35℃,在冬季气温过低时容易冻伤,所以冬季要注意保持温度,最好是不低于10℃。

土壤选择:飘香藤对土壤的要求不高,适应性较强,但以富含腐殖质排水良好的沙质壤土为佳。

繁殖方法:飘香藤一般用扦插法繁殖,也可以用组织培育的方法快速繁殖。

修剪:飘香藤的修剪一般有两个时间。花期后修剪和春季修剪。花期过后进行修剪可以为飘香藤修型,使其美观。在春季修剪老株,可以促进萌发新枝。
