From northern Madagascar, Euphorbia viguieri is a highly variable group. E. viguieri var. viguieri is a single-stemmed species with ovate, bright green leaves and a stem with relatively short and stiff stipules. Some plants have red markings at the base of the leaves, but this is not consistent among the plants. The flowers are a stunning red and held on a fairly long peduncle. These plants are seedlings in 4-inch pots.
