Blackthorn - Acacia mellifera - Invasive Beauty
A Blackthorn (Acacia mellifera) in bloom during the start of the African summer. This bush is considered an "invasive" species as basically it sucks up all the rain water surrounding its root system, and deny grass from growing around it as sunlight is also consumed first by the bush. Because it prevents grass species from growing, its title as invasive and "problem bush" was given. Naturally it also reproduces at a fast speed.
''Senegalia mellifera'' is a common thorn tree in Africa. The name ''mellifera'' refers to its sweet-smelling blossoms and honey. Its lumber turns pitch black when oiled. Common names of the tree include Blackthorn and Swarthaak. It is listed as being not threatened.
