Invasive Alien Species
Species Name: Thunbergia grandiflora
- Family Name:
- Tropical Asia
- A woody climber with stem reaching 200-500 cm length. Long subterranean stolons often present. Petioles are 4-13 cm long. Leaves opposite, with a cordate, 5-7-nerved base, shallowly to deeply palmati-lobed, 7-18 x 6.5-19 cm. Large flowers with trumpet-shaped, blue or whitish corolla are borne in axillary clusters of 1-2 flowers, or in pendulous racemes; pedicels 4.5-16 cm long. Fruit are globose capsules of 3-5 cm length, containing four flattened seeds; each fruit has a conspicuous, long and woody beak at the end.
- Invaded Habitat:
- Forest, forest edges, riparian habitat, river sides. Sometimes cultivated as ornamental plants, running wild by its stolons, locally sometimes in very great numbers.
- This vigorous climber spreads mainly vegetatively by stolons. The plant develops an extensive tuberous root system with some tubers reaching 50 cm diameter and 3 m length. The fast growing climber smothers all vegetation up to 12 m above ground, especially along rivers, and becomes the dominant ground cover. Dense infestations can kill host trees by the weight of the stems.
