The snow is an evergreen shrub of Rubiaceae. Leaves small, opposite elliptic, entire. Flowering from June to September, the flowers are small and dense, white, and small white flowers are covered with branches like snowflakes, hence the name Snow Six. Its slender branches and dense branches are suitable for pruning and modeling, and are suitable for garden cultivation, low hedgerows, potted plants or bonsai.

Originated in southeast, central and Viet Nam of China, it is widely cultivated in various places and is suitable for potted plants or bonsai in the north. I like sandy loam with good drainage, warm environment, plenty of sunshine and humidity. In addition to the original varieties of snow willow, there are two varieties of snow willow in Phnom Penh and snow willow. Snow willow in Phnom Penh is cultivated in semi-shade.

In the snow, each plant can be pruned into clusters or sparse branches. Usually, we should pay attention to picking the heart and pruning dead branches, too dense branches and short branches. Indoor cultivation in autumn in the north can be placed in the semi-shade of coffee table and table corner. Do not apply fertilizer in winter, and spray water on the leaves 1 ~ 2 days to keep the leaves clean. Potted soil should be kept semi-moist.
