Among the 21 leaves offered to Lord Ganesha during Patra Pooja/leaves offering ritual, Arka/Yekka leaf is one of them.
Pooja to Lord Hanuman is incomplete without the offering of a garland made with Arka flowers or Arka leaves. Hindus worship the plant and the leaves are used while having a bath on Rathasapthami/festival of Sun god. In the ancient scripts of Ayurveda, Arka is mentioned as a healing herb. There are two varieties of this plant, the plant with the white flowers is said to be more sacred and its botanical name is Calotropis Procera and the other with lilac colored flowers is called as Calotropis Gigantean.

Arka means “ray of light” in Sanskrit and the Arka plant is native to India and grows in dry wastelands. It grows to a height of 3-5 meters. Its branches are thick and ash colored. When the plant is cut or broken, a milky sap oozes out of it, hence the name Giant Milkweed. Another common name of the plant “Crown Flower” is justified by the fact that the flowers are clustered into a bunch and each of these beautiful flowers has five petals with a structure in the middle resembling a crown. The mature leaves are large, greenish gray, 8 – 12 cm long and 5 – 7 cm broad. The fruits of these trees are greenish gray, puffed up, 10 – 12 cm long. The fruits contain numerous seeds with tufts of silky hair at one end to help it fly.
