牽牛花屬常綠草質藤本，廣佈於大西洋、太平洋和印度洋亞熱帶至熱帶氣候區的沙灘。莖匍匐於地面生長，蔓長可超過20m。根系發達，莖觸地會長出不定根以固定藤蔓。互生羊蹄形或馬鞍形厚實葉片，長3~10cm，寬2~8cm。花1朵或數朵成聚繖花序開於葉腋；花形漏斗狀，花色粉紅，花徑5~7cm，開花壽命半天。開花期夏至秋季。

An evergreen vine in the genus Ipomoea, widely found on the beaches of the Atlantic, Pacific and Indian Ocean subtropical to tropical climates. The vines prostrate on the ground up to 20m long. With a well-developed root system, the stem produces stolons to stabilize the long-trailing vines when touching the ground. Leaves alternate, in a shape of goat foot or saddle, thick, 3-10 cm long and 2-8 cm wide. One or several flowers comprise a cyme on the leaf axil; flowers funnel-shaped and pink, 5-7 cm across, only last a half day. Flowering from summer to autumn.

全日照溫暖至炎熱環境，只要排水良好的介質都可以種植。太長的藤蔓可以剪除，開花後容易結果，若無播種需要，可以摘除殘花以避免結果耗損養分。繁殖使用扦插、壓條或播種法。

The plant grows in a warm to hot environment with full sun and well-drained medium. Trim off the overlong vines to promote fruiting after anthesis. If the seeds are not needed, the residual flowers can be removed to avoid the loss of nutrients. Propagated by cuttings, layering or seeds.

抗風、耐熱、適應高鹽分的沙地，可種植於濱海地區作為防風定沙的地被使用。也適合種植於陽台、花台、駁坎等高處，讓蔓藤下垂營造綠簾的效果。

The plant is wind-resistant,heat-tolerant and able to grow in sandy lands with high salinity, a great windbreak or sand-stabilizing groundcover in coastal areas; also planted on a balcony, flower stand, rip rap and other high places to display the drooping vines and create the effect of green curtain.
