Indian Summer is an old-fashioned gladiolus originally from Africa, valued for colourful blossoms arranged along tall stems. The corms grow best in full sun and well-drained soil; planting them deeply or among sturdy plants can help keep the stems upright.
Plant at one-week intervals to extend the flowering season. Gladiolus flowers also make long-stemmed cut flowers for arrangements.
