Ficus religiosa

Ficus religiosa is associated with Blastophaga quadriceps, an agaonid wasp which acts as its pollinator as this wasp lays its eggs only on trees of this species.

Ficus religiosa is tolerant to various climate zones (Köppen climate classification categories of Af, Am, Aw/As, Cfa, Cwa and Csa) and various types of soils. In Paraguay the tree species occurs in forests at lower elevations, and in China the species has been reported growing at altitudes ranging from 400 metres (1,300 ft) to 700 metres (2,300 ft). In India, being a native species, it occurs both naturally in wild as well as cultivated up to altitudes of 1,520 metres (4,990 ft).

Ficus religiosa is tolerant to widely varying climatic conditions such as Tropical rainforest climate where the region receives more than 60 millimetres (6.0 cm) of precipitation per month, Tropical monsoon climate where average precipitation ranges from 60 millimetres (6.0 cm) in the driest month to 100 millimetres (10 cm), Tropical savanna climate with dry summer where average precipitation ranges from 60 millimetres (6.0 cm) per month in summers to 100 millimetres (10 cm) per month in winters, Warm temperate climate, wet all year where average temperature ranges from 0 °C (32 °F) to 10 °C (50 °F) and it is wet all year, as well as Warm temperate climate with dry summer where average temperature ranges from 0 °C (32 °F) to 10 °C (50 °F) and summers are dry.

Unlike most epiphytic jungle figs, which ring the stems of dicotyledonous support trees from the outside, the epiphytic bushes of F. religiosa are not true stranglers. Their roots penetrate inside the stem of the support, eventually splitting it from within. Ficus religiosa has been listed as an "environmental weed" or "naturalised weed" by the Global Compendium of Weeds (Randall, 2012). It has been assigned an invasiveness high risk score of 7 in a risk assessment prepared for the species' invasiveness in Hawaii by PIER. Such a high score predicts it will become a major pest in suitable climate zones. The major reasons for its invasive behaviour are its fast-growing nature, tolerance to various climate zones and soil types, reported lifespan of over 3,000 years, and its suffocating growth habit as it often begins life as an epiphyte.

Gautama Buddha attained enlightenment (bodhi) while meditating underneath a Ficus religiosa. The site is in present-day Bodh Gaya in Bihar, India. The original tree was destroyed, and has been replaced several times. A branch of the original tree was rooted in Anuradhapura, Sri Lanka in 288 BCE and is known as Jaya Sri Maha Bodhi; it is the oldest living human-planted flowering plant (angiosperm) in the world.[8]

The Bodhi Tree at the Mahabodhi Temple was propagated from the Sri Maha Bodhi, which in turn was propagated from the original Bodhi Tree at this location.

In Theravada Buddhist Southeast Asia, the tree's massive trunk is often the site of Buddhist or animist shrines. Not all Ficus religiosa can be called a Bodhi Tree. A Bodhi Tree must be able to trace its parent to another Bodhi Tree and the line goes on until the first Bodhi Tree under which Gautama is said to have gained enlightenment.[9]

Sadhus (Hindu ascetics) still meditate beneath sacred fig trees, and Hindus do pradakshina (circumambulation, or meditative pacing) around the sacred fig tree as a mark of worship. Usually seven pradakshinas are done around the tree in the morning time chanting "vriksha rajaya namah", meaning "salutation to the king of trees." It claimed that the 27 stars (constellations) constituting 12 houses (rasis) and 9 planets are specifically represented precisely by 27 trees—one for each star. The Bodhi Tree is said to represent Pushya (Western star name γ, δ and θ Cancri in the Cancer constellation).

Plaksa is a possible Sanskrit term for Ficus religiosa. However, according to Macdonell and Keith (1912), it denotes the wavy-leaved fig tree (Ficus infectoria) instead. In Hindu texts, the Plaksa tree is associated with the source of the Sarasvati River. The Skanda Purana states that the Sarasvati originates from the water pot of Brahma flows from Plaksa on the Himalayas. According to Vamana Purana 32.1-4, the Sarasvati was rising from the Plaksa tree (Pipal tree).[10] Plaksa Pra-sravana denotes the place where the Sarasvati appears.[11] In the Rigveda Sutras, Plaksa Pra-sravana refers to the source of the Sarasvati.[12]
