Serissa (Serissa japonica), commonly known as Snowrose or the Tree of a Thousand Stars, is a small, evergreen shrub renowned for its profuse, delicate flowers and glossy, dark green foliage. Native to East Asia, particularly Japan, this charming plant is often grown as a bonsai or ornamental shrub, valued for its compact form and striking appearance. It has earned its common names due to the numerous small, star-shaped white flowers it produces, which bloom abundantly and create a stunning display.

Typically growing 1 to 3 feet tall and wide, Serissa is an ideal plant for smaller spaces, such as container gardens, patios, or indoor settings. Its naturally rounded, bushy growth habit and dense foliage make it an attractive choice for bonsai cultivation, as well as for use in mixed borders, rock gardens, or as a low hedge. The deep green, ovate leaves are small and glossy, contributing to the overall fine-textured look of the plant.

The main attraction of Serissa, however, is its stunning floral display. The plant blooms profusely in spring and summer, with clusters of tiny white or pale pink flowers that resemble stars. These flowers, which appear in large clusters along the branches, add a touch of delicate beauty to the shrub and are often accompanied by a faint, sweet fragrance. The flowers are so numerous that they can completely cover the shrub, creating a dramatic and visually captivating effect.

Serissa thrives in bright, indirect sunlight and well-draining soil, and it appreciates regular watering, though it does not tolerate waterlogged soil. It is sensitive to drought and should be watered consistently, especially during the growing season, to keep its foliage lush and to encourage continued blooming. Serissa is best suited for USDA Hardiness Zones 9–11 and can be grown indoors in cooler climates as a houseplant. In warmer zones, it can be used as an ornamental shrub or in containers.

Serissa prefers slightly acidic to neutral soil and should be pruned lightly to maintain its compact shape and encourage new growth. It responds well to occasional fertilization with a balanced plant food, particularly during its active growing period in spring and summer.

While generally low-maintenance, Serissa can be temperamental in certain conditions. It requires protection from extreme heat, cold, or drafts, especially when grown indoors. It is also prone to root rot if overwatered, so good drainage is essential. Additionally, its small size and delicate flowers make it susceptible to pests like aphids and spider mites, but these can be controlled with appropriate treatments.

Overall, Serissa is an enchanting, compact shrub that offers a beautiful floral display, making it a wonderful addition to gardens, bonsai collections, or as an indoor plant. Its small stature, combined with its starry blooms and glossy foliage, ensures that it will be an eye-catching and delightful plant for any space.
