Charm is a species gladiolus, a group that tends to be hardier and works well as a centrepiece in container gardens. Its colourful flowers grow along upright stems and can also be cut for arrangements.
Grow the corm in full sun and well-drained soil. Planting deeply, or placing it among strong plants, can help support the stems; planting at one-week intervals extends the bloom season.
