Safety Overview
1.Thunbergia Grandiflora — Plant Snapshot
Thunbergia grandiflora, commonly known as the Bengal Clock Vine or Sky Vine, is a robust, evergreen perennial climber belonging to the Acanthaceae family. Native to the tropical and subtropical regions of India, particularly the Himalayan foothills, it has been widely naturalized across other warm climates globally due to its ornamental and purported medicinal value. This vigorous vine is characterized by its woody stems, which can ascend to impressive heights of 15-20 meters, sprawling over supporting structures with ease.
Its foliage consists of large, heart-shaped to triangular-ovate leaves, typically dark green, providing a dense, lush backdrop. The most striking feature of Thunbergia grandiflora is its spectacular, trumpet-shaped flowers, measuring up to 8 cm in diameter. These blossoms exhibit a captivating range of colors, from a vivid sky-blue to various shades of lavender-blue, often accentuated by a prominent yellow or cream-colored throat.
Flowering occurs profusely from late spring through autumn, and in consistently frost-free environments, it can bloom almost year-round, creating a breathtaking cascade of vibrant color and verdant foliage. The fruits are capsules containing seeds, though they are less commonly observed in cultivation compared to the prolific flowering.
