Iris 'Monty's Sweet Blue' is a tall bearded iris that brings sophisticated elegance to spring gardens with flowers spreading more than 5 inches wide, each displaying upright standards and distinctive pendant falls adorned with a bushy beard. This rhizomatous perennial grows 30 to 36 inches tall and thrives in hardiness zones 3 to 10, blooming in May with showy, complex flowers that rival the finest hybrid irises. Once established, it tolerates drought and deer, making it a reliable performer in full sun and average soils, especially when drainage is excellent.

The defining characteristic of bearded irises lies in that bushy beard visible in the middle of each fall, an architectural detail that catches light and invites closer inspection. Flowers spread generously wide and emerge on stems with two or more branches, meaning a single plant produces abundant blossoms throughout its bloom period. This variety handles drought once established and resists deer, so you get reliable spring color without constant fussing or protective measures.
Bearded irises serve as focal points in perennial borders, cutting gardens, and formal landscape designs. Their tall, elegant stems and complex flower structure make them prized for fresh arrangements, where they command attention in any vase.

Plant rhizomes in fall or early spring, positioning them so the growing end tilts slightly uphill if you have clay soil or live in a wet climate. Space plants 12 to 24 inches apart to allow for mature width and good air movement.
Remove diseased foliage and rhizomes promptly, and perform annual cleanup of all debris and spent foliage from iris beds after bloom and before winter. This sanitation practice is the most important step in preventing disease and pest problems.
