Griffinia hyacinthina, a native species of the southern portion of the Brazilian Atlantic Forest (in the states of Sao Paulo and Rio de Janeiro), is the largest species of the genus. In the Northern hemisphere, G. hyacinthina seems to flower in early autumn. A brief drying-off period helped this plant flower. This species does well in shade with warm, humid conditions. Cool temps (40-55 F) in the winter may help induce flowering (?).
