Iris sibirica 'Silver Edge'
Best low-maintenance perennial for gardeners seeking elegant, moisture-loving vertical accents.
The Iris sibirica 'Silver Edge' is a vigorous Siberian Iris cultivar, noted for its lightly ruffled petals edged in silver and slightly blue-tinted foliage, providing a delightful vertical accent in the garden. Originating from the work of breeder Currier McEwen, this perennial thrives near water or in moist, sunny borders. Siberian Irises are known for their easy care, producing flowers in late May, peaking in June, atop sturdy stems. Their deep roots offer drought resistance, and established clumps effectively suppress weeds. The grassy foliage remains erect and green throughout the growing season, offering lasting visual appeal.

Know before you buy
This Siberian Iris performs best in full sun to part shade. While it can tolerate some shade, you will get the most prolific flowering if it receives at least six hours of direct sunlight daily.
Yes, 'Silver Edge' is an excellent choice for moist borders or areas near water features. It thrives in damp soil conditions where many other perennials might struggle.
Yes, Siberian Irises are generally avoided by deer. This makes 'Silver Edge' a reliable choice for gardens in areas where deer pressure is a common concern.
Bareroot plants arrive without soil around the roots, which is a standard and healthy way to ship dormant perennials. Once planted in moist soil, the roots will quickly establish themselves and begin growing as the season warms.
One of the best features of this cultivar is its grassy, vertical foliage, which remains erect and green throughout the entire growing season. It provides a clean, architectural look in the garden long after the blooms have finished.
You should space them 18 inches apart. This allows enough room for the clumps to expand over time, eventually creating a dense, weed-suppressing display.
