Notes
'Professor Blaauw' Dutch iris (Iris hollandica 'Professor Blaauw') is a bulb for borders and low maintenance gardens. It is hardy to USDA zone 6, or down to -10°F (-23°C). This plant likes full sun and average to moist, loamy or clay soil. It blooms in early to late spring and again in early to late summer. Deer and rabbits tend to browse other plants first. It grows 12 to 24 inches tall, so plant it in the middle of a border.
