Needle bush (Γαζία)

Vachellia farnesiana (needle bush), is so named because of the numerous thorns distributed along its branches. The V. farnesiana is originated from Mexico and Central America, but the species has a pantropical distribution incorporating northern Australia and southern Asia.
It is a very popular garden plant, and an important bee foraging tree, and it was spotted in full bloom in my neighbourhood , Nea Demetrias suburb, Volos city, Greece.
