Rubus axillaris: complete guide

Overview

Rubus axillaris, also known as broad ground bramble or Skane bramble, is a low, spreading bramble native to northern Europe. This plant naturally thrives in Belgium, the Netherlands, Germany, Denmark, and Sweden. It is an excellent groundcover plant that spreads via underground runners and thus naturally spreads to cover larger areas.

Rubus axillaris reaches heights of only 30 to 50 cm and spreads to 1 to 2 meters wide. This makes it ideal as a groundcover under trees, in hard-to-reach corners, and for erosion control on slopes. The plant produces pink flowers followed by black, edible berries that are attractive to birds.

Appearance and bloom

The leaves of Rubus axillaris are green, oval-oblong and serrated, with a soft texture. The foliage clusters along the stems which may have a reddish or brownish tint. The plant has small thorns along the stems, although not as sharp as other bramble varieties.

Flowers appear in May and June on the sides of the stems (which justifies the plant name "axillaris"). Each flower is small, approximately 1 to 1.5 cm in diameter, with five pink to white petals. The flowers are very attractive to bees and other pollinators.

After flowering, small, glossy black berries form measuring about 1 cm in diameter. These fruits are edible and very attractive to birds, making this plant bird-friendly for wild garden projects.

Ideal location

Rubus axillaris grows well in both full sun and partial shade. The plant grows faster and produces more flowers in sun, but is also perfect in shade beneath trees.

The plant is very tolerant of wind and grows on exposed locations. This makes it ideal for exposed gardens and slopes.

Soil

Rubus axillaris is very tolerant of diverse soil types. The plant grows in both acidic and alkaline soils. It tolerates both dry and wet soils, although it grows best in normally moist, well-drained soil.

The plant has no special nutrient requirements and grows well in poor soils. Mulching around the plant can help retain moisture.

Watering

Rubus axillaris requires regular watering during the first growing season after planting. Ensure the soil remains moist without becoming waterlogged.

Once established, the plant tolerates drought and does not always need regular watering. During extremely dry summers, however, watering can promote growth.

Pruning

Rubus axillaris requires minimal pruning. The plant spreads naturally via underground runners. Pruning is mainly needed to keep the plant in bounds or to remove dead or damaged parts.

The plant can be cut back in winter to promote more compact growth, although this is not absolutely necessary.

Maintenance calendar

Spring (March-April): Check for winter damage, remove dead parts, and begin regular watering.

Late spring (May-June): The plant flowers. Enjoy the pink blooms.

Summer (July-August): Berries form. Harvest for personal use or leave for birds.

Autumn (September-October): The berries are ripe and birds enjoy them. The plant partially dies back.

Winter (November-February): The plant rests. Minimal watering.

Winter hardiness

Rubus axillaris is very winter-hardy to approximately minus 20 degrees Celsius. This means the plant grows well in all parts of northern Europe. The plant is native to the cold parts of northern Europe so is highly adapted to severe winters.

The plant can survive the harshest winters without any problem.

Companion plants

Rubus axillaris grows well alongside other groundcovers and low shrubs. Good plant combinations are low ferns, ivy, gaultheria, and other bramble species.

The plant is very bird-friendly and attracts many bees and butterflies. This makes it ideal for wild gardens and for gardens aimed at supporting biodiversity.

Closing

Rubus axillaris is an excellent choice for garden owners seeking a low, spreading groundcover with attractive flowers and edible berries. With minimal maintenance needs and excellent winter hardiness, it is perfect for temperate and cold climates. Find your plant at plant nurseries in northern Europe.
