  • Taxonomy

    In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Paulus Johannes Maria Maas from the Netherlands and Nobuyuki Tanaka from Japan. Maas considers C. speciosa to be a synonym of C. indica L., however, Tanaka's DNA assays demonstrate that the C. indica complex can be clearly distinguished from other taxa, as a result he recognises this as a separate species.

    Canna speciosa (Roscoe) Hook.

    C. speciosa is a tall, slender plant with an upright stem covered along its entire length with large, stalkless, gracefully arching leaves. The plant bears heads of striking, bi-colored flowers with scarlet petals and a conspicuous contrasting yellow throat. (D'Orbigny's Dictionnaire D'Histoire Naturelle 1849)
