Gladiolus cardinalis


Add to wishlist Remove from wishlist
Riveting species from mountainous regions in South Africa where it grows on moist cliffs and near waterfalls. Vivid cardinal-red flowers on slender stems with white blazes on the lower 3 petals makes this nearly imperative to own. This is hardy in the PNW thankfully especially if mulched in the event of severe winter cold.
