The Jasminum genus includes about 200 species of tropical shrubs and vines native to Europe, Asia and Australia. Commonly grown garden species include winter jasmine (Jasminum nudiflorum), hardy in U.S. Department of Agriculture plant hardiness zones 6 to 10; common jasmine (Jasminum officinale), hardy in USDA zones 7 to 10; and pink jasmine (Jasminum polyanthum), hardy in USDA zones 8 to 11.
All jasmine species do best in areas that are exposed to either full or partial sun, although common jasmine is able to tolerate deeper shade. Jasmine is not demanding in terms of soil nutrients and will grow well in most well-drained garden soils without amendments.
Plant Spacing and Depth
Winter jasmine is a trailing shrub that grows 3 to 4 feet in height when left unsupported and can climb up to 15 feet high on a wall or trellis. Space individual plants 3 feet apart and they'll quickly grow together to form a dense mass, either on the ground as a ground cover or on a supporting structure.
Common jasmine is a much taller and broader shrub that can reach heights of 15 feet or higher, and it can be pruned and trained as a dense hedge. Space plants 8 feet apart so they're not crowded.
Pink jasmine is a fast-growing vine that grows to about 20 feet in length on a trellis or other support. Space plants at least 8 feet apart to avoid overcrowding.
With all species, plant container-grown plants so that the tops of their root balls are level with the surface of the soil. Plant outdoors in the fall before frost or after the danger of frost has passed in the spring.
Watering and Fertilization
Water jasmine plants thoroughly at the time of planting, and water through the growing season to maintain consistent soil moisture, but not so much that the soil becomes soggy.
Jasmine is a quick grower that usually doesn't need fertilization at planting time, but it may flower better if you give it a high-phosphorus fertilizer, such as 5-10-5 granular fertilizer, during the flowering season. Scatter 2 pounds of the fertilizer per 100 square feet of growing space on the surface of the soil, once in the early spring and again in early summer.
