Iris sibirica 'On and On'

Iris sibirica ‘On and On’
(Siberian Iris)

A reliable McEwen introduction, ‘On and On’ is known for its long bloom window and repeat blooming habit. Dark violet-blue flowers are accented by bright white signals, creating a clean contrast that stands out beautifully in the garden.

Blooming from early midseason into late season, this diploid variety helps extend the Siberian Iris display. Its upright, grassy foliage adds structure and texture even after flowering, making it a strong choice for perennial borders, naturalized plantings, and moist garden areas.
