About this plant
Gladiolus oppositiflorus is a graceful bulbous perennial known for its elegant, funnel-shaped flowers that bloom in shades of pale pink to soft orange. The flowers appear in dense, vertical spikes from late summer into early fall, creating a dramatic display in the garden. Each blossom is delicately marked with darker streaks, adding depth and interest to the floral arrangement.
Native to southern Africa, particularly in regions of South Africa, Gladiolus oppositiflorus thrives in warm climates and brings an exotic flair to borders and cut flower arrangements. Its late-season bloom makes it a valuable addition to extend garden color into autumn.

Design tip
Late flowers extend the season, so set it behind or beside plants that finish in midsummer. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
Where to see it
This plant can be seen in the perennial border at the Bellevue Botanical Garden.
