The plant features dark green leaves with a scallop-edged and wrinkled appearance, forming a basal clump. When in bloom during the summer, the flower stems rise another 12in or 30cm above the leaves.

Cultivation: Tips for Growing Stachys officinalis ‘Hummelo‘:
Stachys officinalis ‘Hummelo’ is a relatively low-maintenance plant that can thrive in a variety of garden settings. By following a few key cultivation tips, you can ensure the successful growth and long-term health of this versatile perennial.
Light Requirements: Stachys officinalis ‘Hummelo’ performs best in full sun to partial shade. While it can tolerate some shade, providing it with at least 4-6 hours of direct sunlight each day will promote vigorous growth and abundant flowering. In regions with particularly hot and intense sun, a bit of afternoon shade can help protect the plant from scorching.
Soil Conditions: This perennial prefers moist but well-drained soil. It is adaptable to different soil types, including loam, sandy soil, or clay, as long as the drainage is adequate. If your soil tends to retain water and become waterlogged, amending it with organic matter, such as compost or well-rotted manure, can improve drainage. Avoid overwatering, as excessive moisture can lead to root rot and other fungal diseases.
Watering: While Stachys officinalis ‘Hummelo’ appreciates consistent moisture, it is essential to strike a balance and avoid waterlogging the soil. Water the plant thoroughly when the top inch of soil feels dry to the touch, and aim to maintain even moisture levels. Mulching around the plant can help retain moisture and regulate soil temperature.
Fertilization: Stachys officinalis ‘Hummelo’ is generally not a heavy feeder and can thrive in moderately fertile soils. Prior to planting, incorporating compost or a balanced slow-release fertilizer into the soil can provide a nutrient-rich foundation. Avoid excessive use of high-nitrogen fertilizers, as this can promote lush foliage at the expense of flower production.
Deadheading and Pruning:
Regular deadheading, which involves removing spent flowers, is beneficial for Stachys officinalis ‘Hummelo.’ This practice not only improves the plant’s appearance but also encourages continuous blooming throughout the growing season. Additionally, removing faded flower stems can help redirect the plant’s energy into foliage growth and promote a neat and tidy appearance. In late fall or early spring, you can cut back the entire plant to the ground to rejuvenate it and promote fresh growth.
Division: Over time, Stachys officinalis ‘Hummelo’ can form dense clumps, and dividing the plant every few years can help maintain its vigor. Spring or early fall is the ideal time for division. Dig up the clump and carefully separate it into smaller sections, ensuring each division has a healthy root system. Replant the divisions in prepared soil, water them well, and provide appropriate care as they establish themselves.
Pest and Disease Management: Stachys officinalis ‘Hummelo’ is generally resistant to pests and diseases. However, it may occasionally attract snails and slugs, particularly in moist conditions. Regular monitoring and employing natural pest control methods, such as handpicking or using organic slug repellents, can help keep these pests under control.
Uses in the Garden:
Stachys officinalis ‘Hummelo’ is a versatile plant that can be utilized in various garden settings. Its clump-forming growth habit makes it suitable for borders or as ground cover. The plant spreads through creeping stems, creating a lush and visually appealing display. It is generally disease-free and pest-free, but occasional attention may be required to protect it from snails and slugs.
Historical Medicinal Uses: Stachys officinalis ‘Hummelo’ holds a historical reputation for its medicinal properties. Different countries in Europe have incorporated this plant into their traditional medicine systems. It has been utilized for various purposes, including the treatment of arthritis, gout, gastrointestinal issues, and other ailments.
