丝瓜（Luffa acutangula）蔬菜植物的黄色花朵。 2025年7月28日，佛罗里达州。

opical climbing vine, also known as angled luffa, produces bright yellow, five-petaled flowers that are either male or female on the same plant. The plant has hairy leaves, yellow flowers, and produces long, ridged gourds that become fibrous as they dry. The plant itself is highly valued for its young, ribbed fruit, which is a nutritional powerhouse rich in fiber and vitamin C.
