Neem

Neem is one of two species in the genus Azadirachta, and is native to India, Pakistan, and Bangladesh growing intropical and semi-tropical regions. It is a fast-growing tree that can reach a height of 15–20 metres (49–66 ft), rarely to 35–40 metres (115–130 ft). It is evergreen, but in severe drought it may shed most or nearly all of its leaves. The branches are wide and spreading. The fairly dense crown is roundish and may reach a diameter of 15–20 metres (49–66 ft) in old, free-standing specimens.  Its fruits and seeds are the source of neem oil.
