Carolina-JasmineCarolina Jessamine

Jasmines can be either deciduous (leaves falling in autumn) or evergreen (green all year round), and can be erect, spreading, or climbing shrubs and vines. Their leaves are borne opposite or alternate. They can be simple, trifoliate, or pinnate. The flowers are typically around 2.5 cm (0.98 in) in diameter. They are white or yellow in color, although in rare instances they can be slightly reddish. The flowers are borne in cymose clusters with a minimum of three flowers, though they can also be solitary on the ends of branchlets. Each flower has about four to nine petals, two locules, and one to four ovules. They have two stamens with very short filaments. The bracts are linear or ovate. The calyx is bell-shaped. They are usually very fragrant. The fruits of jasmines are berries that turn black when ripe.

Carolina Jessamine also know as is a twining vine in the family Gelsemiaceae, native to warm temperate and tropical America from Guatemala north to the Southeastern United States. It can grow to 3–6 m high when given suitable climbing support in trees, with thin stems. The leaves are evergreen, lanceolate, 5–10 cm long and 1-1.5 cm broad, and lustrous, dark green. The flowers are borne in clusters, the individual flowers yellow, sometimes with an orange center, trumpet-shaped, 3 cm long and 2.5–3 cm broad. Its flowers are strongly scented and produce nectar that attracts a range of pollinators.

Jasmines are native to tropical and subtropical regions of Asia, Africa, and Australasia. Of the 200 species, only one is native to Europe. Their center of diversity is in South Asia and Southeast Asia.

Although not native to Europe, a number of jasmine species have become naturalized in Mediterranean Europe. For example, the so-called Spanish jasmine or Catalonian jasmine (Jasminum grandiflorum) was originally from Iran and western South Asia, and is now naturalized in the Iberian peninsula. Jasminum fluminense (which is sometimes known by the inaccurate name “Brazilian Jasmine”) and Jasminum dichotomum (Gold Coast Jasmine) are invasive species in Hawaii and Florida. Jasminum polyanthum, also known as White Jasmine, is an invasive weed in Australia.

Toxic Principle:
All parts of this plant are toxic and contain the toxic strychnine-related alkaloids gelsemine and gelseminine and should not be consumed.

Poisoning Symptoms include:
The sap may cause skin irritation in sensitive individuals. Children, mistaking this flower for Honeysuckle, have been poisoned by sucking the nectar from the flower. The Nectar is also toxic to honey bees, and causes brood death when gathered by the bees.

Despite the hazards, this is a popular garden plant in warmer areas, frequently being trained to grow over arbors or to cover walls.
