Description

Black Monarch is a dramatic, dark-toned bloomer with velvety petals in deep maroon to near-black shades that look especially rich in late-summer light. Its full, layered form creates a bold focal point in the garden and makes striking, moody cut flowers—pair it with whites, blushes, or warm oranges for unforgettable contrast.
