Bearded Iris: A Dazzling Array of Colors and Forms

Classic Rhizomatous Perennials for Sun

The most widely grown irises are bearded types growing from rhizomes (though beardless rhizomatous and bulbous irises also exist). They offer a staggering range of colors, combinations, and plant sizes.

Growing Basics

• Type: Rhizome.
• Zones: 1–24, 30–45.
• Light: Full sun or light shade.
• Water: Regular during growing season.

Planting

• Cold-winter zones: Plant July or August.
• Hot-summer zones: Plant September or October.
• Space rhizomes 1–2 feet apart; set tops just below soil surface, spreading roots out.

Divide every few years to maintain vigor. A garden staple for late spring drama.
