Sanguisorba: A Guide to Growing and Caring for the Versatile Burnet
Introduction
Sanguisorba, commonly known as burnet, is a beautiful and easy-to-grow herbaceous perennial that has become increasingly popular in recent years due to its adaptability and ornamental value. With its showy flowers and attractive foliage, sanguisorba adds interest to gardens from late summer to autumn, when many other plants are fading.
Varieties and Characteristics
Sanguisorba comes in a wide range of varieties, each with unique characteristics. Some popular varieties include:
- Sanguisorba ‘Tanna’: A compact variety with wine-red blooms and blue-gray foliage.
- Sanguisorba hakusanensis ‘Lilac Squirrel’: Upright stems with fluffy pink-purple flower heads that resemble squirrel tails.
- Sanguisorba officinalis ‘Red Thunder’: Tall flower spikes above feathery foliage, ideal for prairie-style plantings.
- Sanguisorba canadensis: Thrives in damp soils and produces large, white flowers contrasted by hairy, pinnate leaves that turn red in autumn.
Growing Conditions
Sanguisorba prefers fertile, moist but well-drained soil in full sun or partial shade. It is a hardy plant that can tolerate periods of drought once established.
Planting
The best time to plant sanguisorba is in autumn, during mild spells in winter, or early spring. Avoid planting in summer unless you can keep the plants well-watered.
- Prepare the soil by adding organic matter, such as compost or manure, to improve drainage and fertility.
- Dig a hole twice the width of the root ball and just as deep.
- Place the plant in the hole and fill in around the roots with soil, firming it gently.
- Water thoroughly and keep the soil moist until the plant is established.
Care
Once established, sanguisorba requires minimal care.
- Watering: Water regularly, especially during hot, dry weather.
- Fertilizing: Apply a balanced fertilizer once a year in spring.
- Pruning: Cut back dead stems to the ground in autumn or early spring.
- Mulching: Mulch around the plants with compost or chipped bark to retain moisture and suppress weeds.
- Supporting: Tall-growing varieties may benefit from support, especially in windy areas. Use grow-through supports or insert twiggy hazel stems around the clump.
- Division: Divide congested clumps every 3-4 years by carefully cutting the root ball into sections and replanting them.
Pests and Diseases
Sanguisorba is generally trouble-free once established. However, it can occasionally be affected by pests such as aphids or slugs. Good garden hygiene and the use of organic pest control methods can help prevent problems.
Uses in the Garden
Sanguisorba is a versatile plant that can be used in a variety of garden settings.
- Borders and beds: Plant sanguisorba in groups or repeat plantings to create a stunning display.
- Prairie-style plantings: Sanguisorba’s airy habit and ability to tolerate drought make it an excellent choice for prairie-style gardens.
- Meadows: Sanguisorba can be used to add color and texture to wildflower meadows.
- Containers: Smaller varieties of sanguisorba can be grown in containers on balconies or patios.
Culinary Uses
While not typically grown for ornamental purposes, the culinary herb salad burnet (Sanguisorba minor) belongs to the same group of plants. Its young, tender leaves can be used in salads and other dishes.
Conclusion
Sanguisorba is a beautiful and versatile plant that is easy to grow and care for. With its showy flowers, attractive foliage, and adaptability to different garden conditions, sanguisorba is a valuable addition to any garden.
