Understanding the Nika Tree
The Nika tree, scientifically known as Vitex negundo, is also known as the Chinese Chaste Tree, Five-leaved Chaste Tree, and Horseshoe Vitex. This adaptable plant grows as an erect shrub or small tree, reaching 2 to 8 meters in height. Its bark is reddish-brown and often appears grayish and peeling.
Its leaves are a distinguishing feature, arranged in a digitate pattern with three to five leaflets, the central one larger. These leaves are dull green on the upper surface, paler beneath, and release an aromatic scent when crushed. They are oblong, measuring 5 to 15 centimeters long and 1 to 4 centimeters wide, with tapered tips and rounded bases.
Small, numerous flowers emerge in panicles, ranging from 10 to 20 centimeters long. These blossoms display shades of violet-blue or white to blue, each measuring around 5 to 7 millimeters. After flowering, the tree produces small, ovoid, one-seeded fruits that mature into a black or purple-black drupe, 1 to 1.5 centimeters in size.
