Japanese Snow Rose (Serissa japonica) Starter in 4" Pot
 
Japanese Snow Rose is a delicate, flowering subtropical species known for its tiny leaves, fine branching, and profusion of small white flowers. It is highly valued for bonsai due to its ability to develop dense foliage and an elegant structure when properly trained. However, it is sensitive to environmental changes, requiring consistent care for best results.
As a Bonsai:
 
Serissa japonica is well-suited for small and medium-sized bonsai due to its naturally fine foliage and strong response to pruning. It requires stable conditions, as it is sensitive to sudden changes in temperature, humidity, or watering. With proper care, it develops a beautiful, compact canopy and a refined, aged appearance.
 
📢 This is a subtropical species—it thrives in warm temperatures during the growing season and should be grown outdoors in warmer months. It should be brought indoors when night temperatures approach 40°F. For optimal health, it benefits from a short pseudo-dormancy period during winter, with at least a month of daytime temperatures around 55-65°F.
