During spring and summer, many people become concerned about plants growing in their ponds. This concern may or may not be justified, because aquatic plants are desirable for many pond management goals. Lotus (Nelumbo lutea) is a conspicuous emergent aquatic plant that frequently grows in local ponds. Lotus has several other common names such as yoncopin, water chinquapin, yellow nelumbo, pond nut, rattle nut and duck acorn. Lotus has large, round, entire leaves that float on the water or perch above the water. A lotus leaf does not have a slit unless it is torn. The flower is large and pale yellow. The stalk bearing large seeds bends over in the fall, and the large holes in its flat surface cause it to resemble a shower head. It typically grows in water 1 to 6 feet deep and seldom persists long in water deeper than 7 feet.
