Ranjai (Clematis gouriana), also called Gourian or Indian Clematis, is a fast-growing woody climber native to the Indian subcontinent and the Himalayan foothills. In Marathi it is known as Ranjai, Gometi or Morvel. It scrambles over fences, trellises and trees, reaching 6 to 8 metres, and is valued for the froth of small, fragrant, creamy-white flowers it produces through the monsoon and into winter.
After flowering, the blooms give way to attractive feathery, silvery-grey seed plumes that persist on the vine and add ornamental interest long after the flowers fade. The compound, slightly toothed leaves form a dense green cover, making it a useful screening climber for Indian gardens.
Beyond its ornamental value, the plant has a long history in Indian folk and Ayurvedic medicine and its flowers are sometimes used in worship. It is hardy, undemanding and well suited to tropical and subtropical conditions across much of India.

Growing tips
<p>Plant at the onset of the monsoon (June to July) so the vine establishes with natural rainfall. Provide a sturdy trellis or support from the start, as it grows vigorously.</p><p>Mulch the base to keep the roots cool and moist while letting the top of the plant enjoy full sun. Feed with compost before the monsoon for the best flush of monsoon-to-winter flowers, and hard-prune after flowering to keep the climber tidy and encourage fresh growth.</p>
