Snowrose is a delicate, stiffly-branched evergreen to semi-evergreen shrub native to the subtropical woodlands and streambanks of India, China, and Japan. Hardy in zones 7-9, this compact plant grows 2-4 feet tall with a slightly wider spread, producing showy flowers from April through September that earned it the poetic name 'tree of a thousand stars.' The variegated foliage adds textural interest year-round, while its moderate care needs and preference for consistently moist, well-drained soil make it a rewarding choice for gardeners who can provide the stable growing conditions it craves.

Snowrose blooms prolifically for six months straight, transforming into a cloud of showy flowers from spring deep into fall. Its stiffly branched habit and evergreen character create architectural interest even when flowers aren't present, and the variegated foliage catches light beautifully in partial shade. This shrub thrives in the precise conditions it naturally inhabits: moist open woodlands with dappled sun, making it especially valuable for gardeners with part-shade beds who want consistent, long-season color without serious pest or disease pressure.
Snowrose excels as a flowering hedge or ornamental shrub in mixed borders, particularly where its reliable, long-blooming habit can anchor a partially shaded garden bed. It works well in containers when given consistent moisture and appropriate light, and its compact, stiffly branched form responds well to light shaping to maintain an attractive silhouette.
No timeline data available yet for this variety.
Start seeds indoors in a warm location, maintaining a temperature of 70-80°F. Timing should allow seedlings to be ready for transplant 6-8 weeks before your last frost date. Keep soil consistently moist but not waterlogged during germination and early growth.
Harden off seedlings over 7-10 days by gradually exposing them to outdoor conditions. Transplant outdoors after the last frost date when soil temperatures have warmed and the shrub can be planted into consistently moist, well-drained soil in a partial shade location with morning sun and afternoon shade.
Deadhead flowers after bloom to encourage continued flowering. Light shaping can be applied to maintain an attractive branched form, though the shrub's stiffly branched natural habit requires minimal pruning. Avoid severe pruning, as this shrub responds best to gentle maintenance that respects its architectural growth pattern.

“Serissa japonica represents a genus with only a single species, historically known as S. foetida before taxonomic revision. This evergreen shrub was collected from subtropical ecosystems across three Asian countries, thriving in the moist, open woodlands and forested slopes where it naturally occurs. The plant's journey to Western gardens reflects a broader interest in Asian ornamentals, and the variegated cultivar 'Variegata' represents selective breeding to enhance its ornamental appeal for container and border gardening.”
