Description

The Star jasmine is perhaps the most widely grown ornamental vine throughout the Inland Empire. It is a vigorous evergreen vining plant with glossy dark green foliage. When grown as a vine, its stems can reach 25-30 ft. in length; it can also be clipped and maintained as a ground cover 18-24 in. tall. Leaves are elliptical in shape, have pointed tips and grow 2-3 in. long; large clusters of deeply fragrant and attractive white flowers occur in late spring to early summer.

Star jasmine is best known for its sweet flower fragrance in Southern California gardens. While this fragrance provides a dominant feature, glossy dark green foliage and manageable growth habit helps make it a popular plant in both commercial and residential landscapes. It has proven to be highly adaptable to cold and heat, sun and shade and a variety of soil types. However, it grows best in loamy soils, with regular moisture and protection from hot sun to keep its rich color and prolong its flowering cycle. It can cover large and small spaces as a ground cover, be trained on trellises and can cascade over walls and banks. It is included on the Crape Myrtle Cottage Garden palette for its handsome evergreen foliage character and abundant, scented flowers.

Water Needs

The Star jasmine vine grows best without moisture stress. Regular irrigation is recommended throughout the year. The chart shown below provides a baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. The high and low range of moisture indicates it can grow with varying amounts of water; higher amounts of water in spring will result in stronger flowering performance and better summer foliage character.

Maintenance

Prune to space limitations of what the vine is growing on. Covers fences, arbors, or lattices. Prune as needed throughout the year, but be careful not to prune off too many buds before spring blooming period (D). Also sometimes used as a groundcover in shade. To maintain in this situation, prune as needed to keep off of paths and walks and as needed to control height. However, many better and lower water groundcover choices are available for most garden situations (S).
