Luculia gratissima is a species of flowering plant in the family Rubiaceae. It is an ornamental plant that is found from the central Himalayas to northern Indo-China.[1]
The Latin specific epithet gratissima means "most pleasing" or "most agreeable".[2]
It is a large shrub or even a small tree growing to 4m (13feet) tall by 1.5m (04.9feet) broad, with pointed ribbed leaves, and clustered fragrant pale pink flowers in autumn and winter. As it does not tolerate temperatures below 5C, it requires cultivation under glass in temperate zones. However, it may be placed outside in a sheltered, sunny spot during the summer months. It is a recipient of the Royal Horticultural Society's Award of Garden Merit.[3]
