Selected for the exotic appearance of its large leaves, elephant ear (Colocasia esculenta) is used as an ornamental garden plant. It belongs to the Araceae family and its common names include cocoyam, taro and dasheen.

Pelargoiums---native to southern Africa---grow best in well-drained, sandy soil. They thrive in full sun, are heat-tolerant and are often identified as geraniums, although they are a more delicate plant. They both belong to the same family---Geraniaceae. The many varieties of pelargoniums grow long, intricate flowering stalks that produce delicate purple, pink, orange, red or white blossoms.
Gladiolus species are native to southern Africa and South Africa's Cape area, where over 100 native species of gladiolus grows, as stated by Dace Selinger of the University of Arizona. Gladioli belong to the Iridaceae family and are a common African flowering plant cultivated in many home gardens around the world. The flowers blossom in many solid and bi-colors including purple, white, pink and green, and some varieties closely resemble iris blossoms. They are a popular cut flower---grown to cut for decorative floral arrangements---and this regular cutting or pruning promotes the growth of another round of flowers. Gladioli grow well in full sun and well-drained soil.
