Description

Iris × robusta ‘Gerald Darby’ is a standout hybrid water-edge iris celebrated for its dramatic purple-black spring foliage that gradually ages to deep green, creating months of interest even before the flowers appear. Emerging from its marsh-iris parentage (I. fulva × I. versicolor), this hardy cultivar thrives in consistently moist soils and naturalized water garden settings. Its early-season richness gives way to elegant violet-blue flowers held on strong stems, offering both color and structural height. Known for its toughness, adaptability, and striking spring show, ‘Gerald Darby’ has become a favored choice for pond margins, rain gardens, wet meadows, and naturalized plantings, earning recognition in specialty water-garden and native-inspired landscapes.

Deep purple-black new foliage that transitions to green as the season progresses
Vigorous, moisture-loving hybrid ideal for ponds, streams, wet meadows, and rain gardens
