It has delicate, richly blue flowers, narrow leaves, and bushy stems.[8][9] Its roots are fibrous, fleshy, and fusiform. These roots, and the plant's buried rhizome, make it very resistant to prairie fires.[9]
The species was first described by Charles Baron Clarke in 1881.[10]Commelina madagascarica is one of the most common plants found in the pseudo-steppe grasslands formed anthropogenically by grass fires in Isalo Massif.[11] Generally, it is common to dry prairies and rocky areas between 1,500 meters (4,900 ft) and 2,000 meters (6,600 ft) above sea level.[9]
