Ideally, it is best to provide the plant with about one gallon of water per week under normal weather conditions. In very hot weather, it may require an additional half gallon to maintain proper moisture levels, but be sure to avoid overwatering as the plant does not like soggy soil. Cut back on water in the fall as the plant prepares for dormancy.
- Light
Great Burnet thrives in full sun to partial shade. It prefers a spot where it can receive at least six hours of direct sunlight daily. However, in very hot climates, protection from the intense afternoon sun with some dappled shade is beneficial to prevent stress on the plant.
- Temperature
Great Burnet is tolerant to a range of temperatures but grows best in conditions between 60 and 75 degrees Fahrenheit. It can survive minimum temperatures down to around 0 degrees Fahrenheit but may suffer if exposed to extremes beyond this range for prolonged periods. Ensuring good air circulation can help it withstand higher temperatures in the summer.
- Pruning
To maintain a tidy appearance and promote vigorous growth, prune the Great Burnet in late winter or early spring before new growth starts. Deadheading the spent flower stalks during the growing season can encourage more blooms. Cut back the entire plant to the ground after the first frost to prepare it for winter.
- Cleaning
As needed
- Soil
The Great Burnet prefers moist, well-drained soil with a high organic matter content; loamy soils are ideal. Aim for a pH range of 6.0 to 7.0 for optimal growth.

- Life cycle
Sanguisorba 'Blackthorn', commonly known as Great Burnet, begins its life cycle as a seed, which requires a period of cold stratification to promote germination. Once conditions are favorable, usually in spring, the seed germinates, and seedlings emerge, developing into young plants with a basal rosette of pinnate leaves. As the plant matures, it develops a strong root system and sends up tall, upright stems in late spring to early summer. By midsummer, the Great Burnet produces distinctive dark maroon to purple bottlebrush-like flower spikes that are pollinated by insects. After pollination, seeds develop and are eventually dispersed near the parent plant or carried further by wind or wildlife. The plant goes dormant in winter, retreating to its rootstock before resuming growth in the next season.
- Propogation
Propogation time
Spring to summer
Sanguisorba 'Blackthorn', more commonly known as Great Burnet, is typically propagated by division, which is considered the most popular method for this perennial plant. The ideal time for division is in the spring or early fall when the plant is not in active growth. To propagate by division, carefully lift the plant from the ground and use a sharp spade or knife to divide the clump into smaller sections, ensuring that each new section has a portion of the root system and several shoots. The divisions can then be immediately replanted in a prepared garden bed or pot, spaced about 18 inches apart to allow for growth. After planting, water the new divisions thoroughly to help establish them. This method allows for the quick multiplication of plants while maintaining the traits of the parent plant.
