As per Matsya Purana, Goddess Ira is the mother of all
trees, shrubs and creepers. She is thus the mother of all plants in Hinduism. Ira, a daughter of Daksha Prajapati, was the mother
of three daughters. Her daughters were Lata (creeper), Valli (creeping plants)
and Virudha. They became in turn mothers of trees, plants and shrubs.
Ira means water and since the vegetable kingdom cannot subsist
without water. Ira thus became the mother of all vegetation.
Lata created creepers, flowerless plants growing in sandy
regions, as well as trees with flowers and fruits.
Valli created bushes and grasses of all kinds.
It must be noted here that as per Devi Mahatmya (Markandeya
Purana 91. 48-49), Goddess Shakambhari is the mother of all plants. She
appeared after a severe drought and blessed the earth with vegetation.
The same Markandeya Purana (48. 3-26) also suggests that
plants and tress appeared from the hair in the body of Brahma.
From time immemorial Hindus was have associated vegetation
with Mother Goddess. Terracotta images of plants appearing from the womb of Mother Goddess was part of Harappa civilization.
