‘Penhill Dark Monarch’ is pure decadence — moody, majestic, and magnificently wild. Her enormous, tousled blooms are a swirl of deep plum, magenta, and smoky rose, with long, twisted petals that curl and ripple like silk ribbons in the breeze. Each bloom looks slightly different, giving her a wonderfully painterly, untamed quality. Towering and theatrical, she brings serious drama to the late-summer garden — a true monarch among dahlias, ruling with elegance, flair, and a touch of mystery.
