It features coarse, hairy leaves and bell-shaped flowers that are typically purple, blue, pink, or white. It grows outdoors to a height of about 1-3 feet and spreads via rhizomes. People grow it for its attractive foliage and flowers, and historically for its medicinal properties (though this is now largely avoided). It is primarily an outdoor plant and does not thrive indoors.
Mexican Orange Blossom
Choisya ternata
Choisya ternata, commonly known as Mexican Orange Blossom, is an evergreen shrub prized for its fragrant, white flowers and glossy, aromatic foliage. It typically grows to a height and spread of 1-2 meters. The plant is native to Mexico and is primarily grown outdoors as an ornamental shrub in gardens and landscapes. While it can be grown in containers, it thrives best in well-drained soil and full to partial sunlight. People grow it for its attractive appearance, fragrant flowers, and relatively low maintenance requirements.
