'''''Serissa''''' is a genus of [[flowering plant]]s 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'''''.
Snowrose and tree of a thousand stars are different cultivars. The only method of differentiating is measuring the difference in the shape and size of the flowers produced.
It is an [[evergreen]] or semi-evergreen [[shrub]], 45-60 [[Metre#SI_multiples|cm]] high, with oval, deep green, rather thick [[leaf|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 [[flower]]s are funnel-shaped and 1 cm wide. They first appear as pink [[bud]]s but turn to a profusion of white flowers. Fertilizing is especially important during the long flowering period.
Many [[cultivar]]s 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.
Synonyms ''Leptodermis nervosa, Leptodermis venosa, Buchozia coprosmoides, Serissa kawakamii, Serissa serissoides, Serissa democritea, Serissa foetida, Dysoda foetida, Dysoda fasciculata, Democritea serissoides, Serissa crassiramea, Serissa foetida forma plena, Serissa foetida forma pleniflora, Serissa foetida var. crassiramea''
