Stachys monnieri 'Hummelo' (now often classified as Stachys officinalis) is an award-winning, high-performance perennial that brings a clean, structural elegance to the sunny garden. This 2019 Perennial Plant of the Year is prized for its low-growing, mounded habit of glossy, textured, dark green leaves that stay tidy and attractive from early spring through frost. Reaching a foliage height of 18 inches with a spread of 18 to 24 inches, it forms a dense, weed-suppressing carpet that remains lush even in the heat of mid-summer.
In mid-summer, 'Hummelo' earns its reputation as a showstopper when sturdy, leafless stems rise well above the foliage to a height of 18 to 24 inches. These stems are topped with dense, upright spikes of vibrant rose-purple flowers that create a vertical, "bottlebrush" effect in the landscape. The blooms are a powerful magnet for butterflies, bees, and other pollinators, providing a reliable nectar source during the peak of the season. Unlike the woolly Stachys byzantina, 'Hummelo' features crisp, green foliage that is highly resistant to "melting out" in humid conditions.
For the most prolific blooming and the tightest mounded habit, plant 'Hummelo' in a location that receives full sun to very light part shade. It is a rugged and versatile perennial that thrives in average to moist, well-drained soil; once established, it shows excellent drought tolerance.
