Black-eyed susan vine (Thunbergia alata) is a vine species native to southern Asia, Madagascar, and Africa. This plant is called black-eyed susan vine because its blossoms resemble the black-eyed Susan. Both plants have bright yellow petals and black centers. Black-eyed susan vine is widely cultivated as an ornamental plant.

This tropical, evergreen shrub grows erect and blooms with bold dark blue or purple flowers through both summer and autumn, making it a lovely choice for hedges, borders, and walls. Though bush clockvine most commonly grows as a bush, it can be 'trained' to grow like a vine (as implied by the name).

Blue trumpet vine (Thunbergia grandiflora) is an evergreen vine native to China, India, and Mainland Southeast Asia. It is often cultivated as a houseplant in environments with temperate climates and widely naturalized. In Australia, it is considered to be a serious environmental weed.

If you’re going to try to grow mysore trumpetvine (Thunbergia mysorensis) at home, keep in mind that it’s a plant for warmer climates. Also, since it’s a climbing plant, you’ll need something sufficiently strong for it to clamber over.

Whitelady (Thunbergia fragrans) is a fragrant (hence the scientific epithet) herb that is cultivated for its white flowers in tropical and sub-tropical regions. It is an invasive species that has become a threat to native plant communities. Though cultivated as an ornamental, whitelady is more commonly found as a weed on roadsides, forest margins, plantation crops, and in thickets.

Laurel clockvine (Thunbergia laurifolia) has elegant lilac and yellow flowers that make it a popular ornamental species. The flowers attract carpenter bees when they open during daylight hours before closing at night. However, this plant has escaped cultivation to become an invasive weed in tropical locations including Brazil.

Black-eyed susan vine 'Arizona Dark Red' is a gorgeous perennial that blooms in warm shades of red. Most Black-eyed susan vines bloom oranges and yellows. It's the red color, symbolizing the Arizona heat, that gives this cultivar its name. Gardeners love this plant, not only for its gorgeous flowers but also because it attracts butterflies and bees.

This cultivar was created for its coloring. Cultivated from the black-eyed susan, the black-eyed susan vine 'Sunny Suzy Brownie' is actually not brown, as it name suggests, but a dark orangey-red with an eye that is much darker in color. The longer it spends in the sun, the deeper its color becomes. Without much sun, it stays a paler orange.

Scarlet clock vine grows across a region of Asia centered around the Himalayas at elevations up to about 2000 m. Its vines produce hanging flowers that can vary in color from deep red to orange or yellow depending on the local temperature. Scarlet clock vine typically needs plenty of humidity to grow well.

As a heat-tolerant climber, the black-eyed susan vine 'African Sunset' can be found as a fast-growing container, accent, and hanging cultivar. Its parentage is unknown. The black-eyed susan vine 'African Sunset' has blooms ranging from apricot and pink to red, reminiscent of a sunset. This explains its name. Gardeners may keep the black-eyed susan vine 'African Sunset' because it is easy to care for and has an extended flowering season.

Natal primrose is a resilient climbing vine that typically adorns trellises and walls with lush foliage and ornamental flowers. Characterized by heart-shaped leaves and a robust growth habit, it thrives in warmer climates where it can receive ample sunlight. The foliage often resembles that of Atriplex, hence its species name, suggesting a historical adaptive imitation for its survival in specific habitats.

Thunbergia neglecta is characterized by its climbing habit and heart-shaped leaves, which are often a lush green. Delicate yellow flowers with a simplistic charm define this plant, blossoming amid the foliage to create a subtle yet enchanting display. Its growth thrives in warm climates with well-drained soils, where it can gracefully twine around structures, showcasing its natural elegance.

Thunbergia natalensis is a species of flowering plant in the family Acanthaceae, that is native to parts of mainland Africa, including South Africa (Limpopo, Mpulamanga, KwaZulu-Natal, East Cape Province), Eswatini, Tanzania, Ethiopia, Malawi and Zimbabwe. It occurs in forest margins, bush and grassland. Normally evergreen, it responds to dry or cold winters by losing its leaves and going dormant. Common names include dwarf thunbergia, Natal blue thunbergia and Natal blue-bell. This handsome plant is cultivated in temperate regions for its masses of summer-flowering pale blue, trumpet-shaped blooms against dark hairy leaves. Growing to around 1 m (3.3 ft) tall, it is best displayed as groundcover in a partially-shaded position.
