Kusha grass

Kusha (Sanskrit: कुश) also known as Darbha (Sanskrit: दर्भ) and Pavitram (Sanskrit: पवित्रम्), are the Sanskrit terms for Desmostachya bipinnata grass. This grass is of literary and ritual significance in Hinduism.

In the performance of Vedic rituals such as the homa and tarpana, the kusha grass is shaped like a ring and is worn by a priest on the ring finger of his right hand. The auspicious day for uprooting the sacred grass Kusha is the amavasya day of Bhadrapada month in Hinduism called as Kusha Amavasya.
