Thunbergia mysorensis

Thunbergia mysorensis, the Mysore trumpetvine or lady's slipper vine, is a species of flowering plant in the family Acanthaceae. A woody-stemmed evergreen, this vine is native to southern tropical India. The specific epithet mysorensis is derived from the city of Mysore.

Description
Thunbergia mysorensis often reaches 6 m and has long narrow medium green leaves. The dramatic and very large pendent hanging blossoms have individual flowers in a bold curved shaped. This is enhanced by their being a rich saturated yellow, with maroon to brownish red outer tip coloring. The vine blooms from spring to autumn.

Cultivation
Thunbergia mysorensis is cultivated as a popular ornamental plant in tropical and sub-tropical gardens, conservatories and greenhouses. It grows quickly in frost-free temperate climates, such as coastal Southern California, with flowers draping down from pergolas and other garden structures. Its sweet nectar is attractive to sunbirds, a very small passerine bird, and hummingbirds. It has gained the Royal Horticultural Society's Award of Garden Merit.
