特色簡介 Feature Description

顧名思義,就是生長型態與葉片形狀,和牽牛花相近的秋海棠,不同的是牽牛花用嫩莖纏繞攀爬,牽牛秋海棠則是用氣生根吸附攀爬。和園區鄰近栽培的山毛櫸秋海棠,兩者都是秋海棠家族中罕見的蔓藤性種類。在1800多種野生的秋海棠中,真正蔓性的種類不出10種。夏、秋季開花,碩大的花序成串懸垂,掛著的白色花朵相當漂亮。

As the Chinese name suggests, Morning-Glory Begonia’s growth pattern and leaf shape is similar to that of Morning Glory. Morning Glory is entwined with tender stems to climb, while Morning Glory Begonias uses aerial roots to attach and climb. Morning-Glory Begonia and the adjacent Beechleaf Begonia are both rare vine species in the begonia family. Among more than 1,800 wild begonias species, less than 10 are trailing. It blooms in summer and autumn, inflorescences are large and white flowers are hung in clusters, which is highly ornamental.
