Snake Gourd
Trichosanthes cucumerina
The Snake Gourd (Trichosanthes cucumerina) is a tropical climbing vine in the Cucurbitaceae producing extremely long, slender, curving fruits that genuinely resemble snakes hanging from a trellis — some reaching over 1.5 meters in length. Both ornamental and edible, the snake gourd is a popular vegetable in South and Southeast Asian cuisines.
• The fruits can grow to over 1.5 meters long and naturally curl like a hanging snake — one of the most unusual-looking vegetables in existence
• Also called "padwal" in Marathi, "chichinga" in Bengali, and "padavalanga" in Malayalam
• The wild form has extremely bitter red fruit, while cultivated varieties are mild and tender
• Often grown as an ornamental curiosity due to its dramatic snake-like fruit
• A close relative of the winter melon and other cucurbits
• The flowers have distinctive fringed, filamentous petals — among the most ornamental in the gourd family

Fun Fact
Snake gourd fruits grow so fast and curl so naturally that growers in India often tie small stones to the tips of the developing fruits to weigh them down and keep them growing straight — without this intervention, a 1.5-meter fruit will twist itself into a perfect spiral, looking exactly like a green serpent hanging from the trellis.
