Burnet Tanna

Burnet 'Tanna' (Sanguisorba) is a relatively adaptable perennial that prefers a sunny location, but it can handle partial shade without any issues. The key to success is soil that should be well-drained but also capable of retaining moisture.

Unlike many other perennials, burnet does not mind heavier clay and loamy soils, provided they are not permanently waterlogged. However, avoid areas where the soil dries out extremely quickly or is sandy.

Yes, that is one of the great advantages of this plant. Burnet handles clay and heavier soils well, as they retain moisture.

Conversely, it will not thrive in light, sandy soils that dry out quickly unless you ensure frequent watering.

The 'Tanna' cultivar is a compact dwarf variety. It only grows to a height of 30 to 50 cm, which is significantly less than the original wild species.

Due to its growth habit, it is perfectly suited for the edges of flower beds. When planting, allow for a spacing of 35–40 cm (approximately 5 to 7 plants per m²) so that the plants form a nice, closed cover while still having enough room to grow.

Burnet 'Tanna' blooms for quite a long time, usually from June to September.

The flowers are very distinctive – they form small, oval heads resembling tiny buttons or cones in a dark burgundy to red color. They float on thin stems above the clump of leaves, which gives the plant a very airy and elegant look.

You do not need to worry about winter protection at all. Burnet 'Tanna' is fully hardy.

It is classified in hardiness zone 4a, which means it can withstand frost down to -34 °C. It is a long-lived perennial that overwinters in our conditions without any problems and without the need for any covering.

Definitely yes! Sanguisorba 'Tanna' is suitable for cutting.

Its small, wine-colored heads on thin stems are a fantastic addition to summer bouquets, providing lightness and texture. They last a relatively long time in a vase and beautifully complement larger flowers, such as roses or coneflowers.

No, the 'Tanna' cultivar does not require support. It is a low-growing and compact variety (up to 50 cm) that holds its shape and does not flop over. Its stems, while slender, are sturdy enough to support the small flower clusters.

Yes, Sanguisorba is a magnet for pollinators.

Its flowers are rich in nectar and pollen, so you will often see bees and other insects on them during the flowering period (June–September). It is a great choice for natural gardens that support biodiversity.

Burnet (Sanguisorba) is a very hardy plant that usually does not suffer from pests (as noted in the description, "Pest-free 🙂").

The only problem that may occur is powdery mildew (a white coating on the leaves). This happens primarily when the plant is stressed by drought or planted in a location with poor air circulation. Prevention involves keeping the soil moist and maintaining the recommended planting spacing.

The best way to propagate this perennial is by division. As it is a long-lived plant, the clumps expand over time. In early spring (before new growth begins) or in autumn, you can dig up the older clump, carefully divide it into several smaller parts with a spade, and plant them immediately in a new location. This will also rejuvenate the plant.

Yes, Sanguisorba officinalis is not poisonous. It is a safe plant to grow in gardens where children, dogs, or cats are present. As the name implies, it was even historically used in traditional medicine.
