Sky vine (Thunbergia grandiflora), also commonly referred to as clock vine, a member of the tropical Acanthaceae family and is an evergreen in frost free climates, where it also produces fruits, but growth slows or stops in cool temperatures.

The clusters of its trumpet flowers will enrich your garden with the vibrant feel from India, its origin. Dramatic lavender-blue flowers on a backdrop of dark green heart-shaped leaves will light up your garden all summer, or all year long in tropical climates. Sky vine growing is rewarding. The plant blooms profusely, and its stunning flowers make great cutting specimens for arrangements. This vine is ideal for covering a fence, pergola, large trellis or an arbor. It sends out long wandering tendrils, which can even grab onto a nearby tree branch, becoming an interesting focal point in the garden. It’s this growth habit which gives the plant its name as well.
