Ligustrum, commonly known as privet, is a genus of shrubs and small trees often used for hedging and topiary. They are characterized by their dense foliage, opposite leaves, and clusters of small, white, fragrant flowers, followed by dark berries. While primarily outdoor plants valued for their adaptability and ease of shaping, some species are occasionally brought indoors, though they rarely thrive due to insufficient light and humidity. They are grown for their formal appearance and ability to create privacy screens.
