About This Plant
Born from the gardens of Massachusetts hybridizers Marty Schafer and Jan Sacks, ‘Cape Cod Boys’ was introduced in 2009 and named with the beauty of Cape Cod in mind—blue bay waters, sandy beaches, and the sweeping curve of the coastline. Its large, dappled blue-violet blooms are finished with a warm golden-yellow signal, creating a beautiful contrast that feels both coastal and timeless.
A standout Siberian iris, ‘Cape Cod Boys’ is a vigorous grower with strong foliage and a long midseason bloom, with rebloom possible in favorable conditions. Its exceptional performance earned it the Morgan-Wood Medal in 2021.
Planting & Care
How to Plant
Choose a spot with 6+ hours of direct sun. Dig a hole twice as wide as the pot and plant at the same depth it was growing, gently loosening the roots. Water deeply after planting and add 2–3 in of mulch, keeping it off the stems. Hardy in USDA zones 3-9.
Watering & Feeding
Water deeply 1–2 times a week for the first season, about 1 in per week. Keep soil evenly moist, especially during heat and dry spells. Top-dress with compost in spring; most perennials don't need much fertilizer.
Pruning & Seasonal Care
Deadhead spent flowers to encourage more blooms. Cut back after a hard frost, or leave stems standing for winter interest and tidy up in spring. Divide every 3–4 years if the center thins. Mulch in late fall to protect roots through the first winter.
