Nelumbo nucifera, also known as the Egyptian bean, sacred lotus, Indian lotus,[1] or simply lotus, is a species of plant in the genus Nelumbo sometimes colloquially called a water lily. They float on the surface of the water. They are the national flowers of India and (unofficially) Vietnam.

The leaves of Nelumbo nucifera contain the flavonol miquelianin and alkaloids such as coclaurine and norcoclaurine, while the whole sacred lotus has bioactive compounds including nuciferine and neferine.

Classification

The lotus is often confused with the true water lilies of the genus Nymphaea.

Botany

The roots are planted in pond or river bottom soil, while the leaves float on the water's surface. The leaf stalks can be up to 200 cm (6 ft 7 in) long, allowing the plant to grow in water to that depth.[2]

Flowers

The flowers are usually found on thick stems rising several centimeters above the leaves. Some cultivated varieties have extraordinary numbers of petals.

Seeds

Lotus seeds are usually oval-shaped, with sizes varying according to varieties. They are generally 1.2–1.8 cm long, with diameters ranging from 0.8 to 1.4 cm and a weight of 1.1–1.4 g.[3]

After lotus seeds have been peeled, you can already eat them (they are considered edible). They are rich in nutrients and can be dried for storage. Their nutritional values can differ due to culture environments and varieties.[3]

Cultivation

Planting

These plants require a nutrient-rich and loamy soil.[4] The first step is to plough the dry field. One round of manure is applied after ten days, just before flooding the field.

Harvest

After two to three months of planting, the stolon is now ready to harvest. The stolon must be harvested before flowering. It is pulled out of the water by pulling and shaking the young leaves in the shallow water.[5]

Uses of lotus

Political

Nelumbo nucifera is the national flower of India. Bharatiya Janata Party uses lotus as its party symbol. Nowadays, as a part of branding strategy, BJP started using its lotus logo in black-and-white in most settings as Electronic Voting Machines (EVM) in India only allow black-and-white logos.

Additionally, the lotus is used (unofficially) as the national flower of Vietnam. Anyone who sets foot in Vietnam can see lotus flowers throughout the land. Between May and August of each year, lotus fields all over the country are immersed in a vibrant pink or white as the blossoms are in full bloom.[6]

There are advocates for the contemporary Government of Vietnam to formally designate this species as the national flower, citing straw polls indicating very high approval from the Vietnamese citizens.[7]

Culinary

Rhizomes

Lotus rhizomes

The rhizomes are 60–14 cm (23.6–5.5 in) long, 0.5–2.5 cm (0.20–0.98 in) in diameter, yellowish white to yellowish brown, smooth, and with nodes and internodes.[8]

Pips

Lotus pip tea is consumed in Korea.

Health use

Medicine

All parts of Nelumbo nucifera are edible, with the rhizome and seeds being the main parts. Traditionally rhizomes, leaves, and seeds have been used as medicine.[9][10]

In Chinese medicine, seeds are used as lian zi xin (蓮子心).[11]

Chemical composition

As mentioned earlier, the leaves of lotus have miquelianin and several alkaloids such as coclaurine and norcoclaurine, while the entire plant itself contains compounds like nuciferine and neferine.
