Penhill Dark Monarch - Dahlia

Let this dramatic beauty reign in your garden! Penhill Dark Monarch is a bold informal decorative dahlia with gigantic 10″+ blooms that weave together smoky plum, raspberry, dusky rose, and buttermilk cream in a rich, painterly blend. Its tousled, ruffled petals give it a textured, almost velvety look that’s equally striking in borders or bouquets.

This variety isn’t just big — it’s a showstopper. The dramatic tones and sweeping informal form add late‑season flair from midsummer through fall, making it a top pick for gardeners and floral designers alike. And yes — those tall, sturdy stems make it a fantastic cut flower for arrangements that demand attention.

Whether you’re after garden royalty or centerpiece‑worthy blooms, Penhill Dark Monarch brings deep, moody color with plenty of personality.
