Yellow Jasmine - The yellow Carolina jasmine (or 'jessamine') is an attractive evergreen vine that tends to remain bushy and compact when grown in bright sun. When shaded though, it will climb up and over adjacent shrubs and trees to heights of more than 20 ft (6.1 m) in its quest for sunlight. The glossy rich green leaves are narrow oblongs with pointed tips and are 2-3 in (5.1-10.2 cm) long by 0.5 in (1.3 cm) wide. They are held in opposite pairs along smooth wiry reddish-brown stems. Small clusters of fragrant yellow tubular flowers are produced from late winter to early spring depending on location and temperature. The showy blossoms are about 2 in (5.1 cm) long and have a flared mouth 1 in (2.5 cm) in diameter.
