Orange clock vine, Thunbergia gregorii, is a tropical, evergreen climber with bright orange flowers. It’s typically grown as a conservatory climber in our British climate, but it can be grown outside if given a sunny, sheltered site or raised in a pot which can be moved indoors in autumn.
A vigorous climber, Thunbergia gregorii will quickly cover a trellis or obelisk. For best results grow in moist but well-drained soil or compost in a sheltered, sunny spot. It can also be grown in containers. Regular deadheading will prolong flowering. Cut back spent flower stems in autumn and apply a dry mulch around the crown of the plant to protect against frost damage. Or move container-grown plants indoors.
