One of my current favorite plants, the apostle iris. Its name comes from the belief that the plant will not flower until the individual plant has at least 12 leaves. I like it for its strong, architectural presence.
With this garden design, I limited my plant palette to three plants: boxwoods, ilex schilling and the apostle irises.
Behind the 5 irises are 10 boxwoods and 3 ilex shillins. I try to plant in 3, 5, and 7 arrangements. I fortified the soil with black cow compost and bone mill. For mulch, 1′ brown river rock.
