  • Description & Ethnobotany
    • Plant Morphology :
      [Others]: Growth Form: Herbaceous perennial with trailing or erect growth habit. Habitat: Occurs in savanna grasslands. Found in shady locations near streams or between rocks that become submerged after heavy rainfall. Stems: Stems are thickly covered in soft, long hairs. Foliage: Opposite, sessile leaves are elliptic with entire leaf margin. They are deeply veined and densely covered in long, soft hairs. Flowers: White or bluish to purplish flowers are bilabiate with a small, bi-lobed upper lip and a large, tri-lobed lower lip. White flowers are uniformly white, while purple flowers have an upper lip streaked with dark purple lines. Flowers are arranged in spike inflorescences and occur between leaf-like bracts that are ovate and hairy. Fruits: Dry, dehiscent fruits are known as capsules. They are oblong and pointed at the tips. Landscaping: This species produces striking bluish flowers. It is not commonly used in landscaping, so it would provide a unique look. This species could be used as a groundcover in poorly drained areas, because it is tolerant of waterlogged soils. It is also shade tolerant, so it could be planted underneath a tree or large shrub. Cultivation: This species grows best in fertile, well-drained soil that is kept moist. However, it is tolerant of waterlogged soils. Propagation: Propagate by seed or stem cuttings. Etymology: The species epithet "canescens" refers to the leaves which are canescent (covered in white, thin hairs).
      Associated Fauna :

      Ethnobotanical Uses :
      Food (Herb & Spice)
      Medicinal
      [Others]: Medicine: Leaf extracts reduced inflammation and provided pain relief in a rat model study by Owoyele et al. (2005). Whole plant extracts are rich in antioxidants which are compounds that remove disease-causing free radicals from the body (Sawadogo et al. 2006). Other: Fongod et al. (2010) found that planting this species as a cover crop in banana plantations reduced the number of weeds by 60 - 100%, repelled snails and improved crop yield.
