Will Pink Jasmine Grow in Zone 7?

Native to western and southwestern China, pink jasmine (Jasminum polyanthum) grows vigorously with twining stems and deep green leaves to a height up to 20 feet. It bears loose clusters of tubular, rosy pink flower buds in early spring that open to white, five-petaled flowers. Mildly fragrant, the blossoms can attract butterflies. Pink jasmine is best grown outdoors only in regions where winter temperatures don't drop below 16 degrees Fahrenheit.
  1. Winter Hardiness

    • Expect pink jasmine to be killed by the winter cold in U.S. Department of Agriculture plant hardiness zone 7, where the average lows dip into the 0 to 10 degree range. Pink jasmine remains evergreen and doesn't sustain much damage in winter in zones 9b through 11. In zone 8b, this plant is killed back to the lower stems or the roots each winter and must rejuvenate in spring.

    Growing Recommendations

    • The limiting factor for growing pink jasmine in zone 7 is winter cold. Planting and growing a vine in a movable container avoids winter dieback issues as long as the plant is moved indoors from December 1 to March 15. Relocate the containerized pink jasmine into an unheated garage next to a sunny window or bring it indoors into a sunny, warm room. If brought into the house, a pink jasmine may begin blooming in late winter or early spring. A chilly unheated room will prevent early flowering and once the plant is placed back outside, it will bloom in April or May.

    Alternatives

    • While pink jasmine is not a hardy outdoor plant in zone 7, other jasmines do survive the winters. Winter jasmine (Jasminum nudiflorum) and yellow jasmine (Jasminum humile) produce yellow blossoms. Confederate jasmine (Trachelospermum jasminoides) bears fragrant white flowers and is a vigorous, large vine. Asiatic jasmine (Trachelospermum asiaticum) is mostly used as a prostrate ground cover and rarely flowers. Carolina jasmine or yellow jessamine (Gelsemium sempervirens) also grows well and quite large in zone 7 landscapes.

    Sunset Climate Zone 7

    • "Sunset" magazine developed extensive climate zones for horticulturists to use in the American West where abrupt changes in elevation make using USDA zones difficult or impractical. Sunset climate zone 7 encompasses the mid-elevation highlands of southwestern Oregon and northern and central California surrounding the Central Valley. Pink jasmine does grow well in Sunset climate zone 7. The hot summers and mild winters that rarely get colder than 20 degrees allow pink jasmine to flourish.
