Oleandra Mollis, also known as the tea olive, is a flowering shrub that produces highly fragrant white or yellow blooms. This beloved shrub has various synonyms that include Osmanthus fragrans, sweet olive, fragrant olive, and mock orange. Sweet olive perfectly describes the sweet, aromatic scent that the plant exudes, while fragrant olive emphasizes the pleasant smell of the blooms. Osmanthus fragrans is the formal botanical name for the species and is also known as the true species of olive.
