鳳眼藍
Pontederia crassipes
植物簡介
Free-floating, aquatic plant typically reaching up to 0.3 - 0.65 m, but occasionally up to 1 m. Large, roundish leaves are slightly cupped, smooth and glossy with entire leaf margin. The ball-shaped leaf stalk at the base of the leaf is filled with spongy tissue that helps to keep the plant afloat. Light purple to blue flowers are arranged on a spike inflorescence. The top petal has a yellow, oval-shaped center surrounded by distinct, dark purple lines that originate from the base, radiate outwards and branch toward the middle and outer edges of the petal. The inflorescence perched on a long stalk can reach up to 0.6 m tall. Fruit is a capsule that contains 3 compartments filled with small, ribbed seeds.
