Japanese: フウセンカズラ - ふうせんかずら(英語表記)balloon vine
Balloon vine - Balloon vine

A climbing annual plant of the Sapindaceae family (APG classification: Sapindaceae). Native to southern North America. The stems are thin, branched, and climb with tendrils, reaching a height of 3 meters. The leaves are 5-10 cm long, bifoliate, and trifoliate, with leaflets deeply lobed into 3. Flowers appear around July on slender pedicels that branch out from the leaf axils, with the lower pedicels forming a pair of tendrils. The white flowers are inconspicuous, measuring about 5 mm in diameter, but the fruits grow suddenly, hanging down as green balloon-shaped plants with 3 edges and a diameter of 3 cm. The name comes from the shape of the fruit, and the English name "balloon vine" means a climbing plant that bears balloon-shaped fruits, and the Japanese name is the same. It is used for hedges and potted plants. Seeds are sown from late April to early May.

Japanese:

ムクロジ科(APG分類:ムクロジ科)のつる性一年草。北アメリカ南部原産。茎は細く、枝分れし、巻きひげではい登り、高さ3メートルになる。葉は長さ5~10センチメートルの2回3出複葉で、小葉は3深裂した3出複葉。花は7月ころ、葉腋(ようえき)から出た細長い花柄に枝分れしてつき、下部の小花柄が1対の巻きひげとなる。花は白色の径5ミリメートル前後で目だたないが、果実は急に大きくなり、径3センチメートルで3稜(りょう)のある緑色の風船形となってぶら下がる。名は、この果実の形に由来し、英名のバルーン・バインは風船形の果実をつけるつる植物の意味で、和名も同様である。垣根や鉢植えに利用される。種子播(ま)きは4月下旬から5月上旬にする。
