"Serissa" is a genus of flowering plants in the family Rubiaceae, containing only one species, "Serissa foetida". It is native to open sub-tropical woodlands and wet meadows in southeast Asia, from India, and China to Japan. It is commonly called Snowrose, Tree of a thousand stars, or Japanese Boxthorn; and was formerly called "Serissa japonica".

It is an evergreen or semi-evergreen shrub, 45-60 cm high, with oval, deep green, rather thick leaves that have an unpleasant smell if bruised (hence its name "foetida"). The upright stems branch in all directions and form a wide bushy dome. It is grown for its neat habit, good coverage of branches and long flowering time. It is also valued for its rough, grey trunk which tends to get lighter in colour with age.

"Serissa" flowers practically all year round, but particularly from early spring to near autumn (Thanksgiving or Christmas). The 4- to 6-lobed flowers are funnel-shaped and 1 cm wide. They first appear as pink buds but turn to a profusion of white flowers. Fertilizing is especially important during the long flowering period.

Many cultivars with double flowers or variegated leaves are also available. 'Pink Snow Rose' has pale pink flowers and leaves edged off-white. Other cultivars include: 'Variegata', 'Variegated Pink', 'Pink Mystic', 'Snowflake', 'Snowleaves', 'Mt. Fuji', 'Kyoto' and 'Sapporo'.

Serissa is one of the most common bonsai, especially in Japan. It is not difficult to maintain as bonsai, but is very fussy. It responds adversely by dropping leaves if over-watered, under-watered, if it's too cold, too hot, or even if just moved to a new location. The plant usually grows back to health when put back to better conditions.
