Bloody cranesbill: complete guide

Overview

Bloody cranesbill (Geranium sanguineum) is a stunning, sturdily built perennial from Europe to the Caucasus distinguished by its intense magenta-pink flowers and long bloom period. Growing naturally on dry slopes and heathland, this plant thrives in full sun and tolerates drought well. With its rich flower color and robust character, bloody cranesbill brings tireless color to sunny gardens from May through October.

In temperate gardens, bloody cranesbill is a classic for sunny perennial borders, rock gardens and dry corners. The plant forms dense groundcover mats through its strong growth and tolerates neglect better than many other garden plants.

Appearance & bloom cycle

Bloody cranesbill reaches heights of 30-50 cm with a spread of 60-80 cm. The plant grows compactly, forming full, densely-packed mats. Leaves are small, finely cut and deeply lobed, often with attractive red-brown fall coloring.

Flowers are the defining feature. Large, approximately 2-2.5 cm in diameter, appearing in countless clusters. Flower color is intense magenta to nearly rose-red, with darker veins accentuating the center. Many cultivars have white eyes. Bloom is unusually long: May through October, sometimes to first frost.

Popular cultivars:

• 'Max Frei': bright magenta
• 'Elsbeth': more pink
• 'Album': white with pink eyes
• 'Striatum': white with pink stripes

Ideal location

Bloody cranesbill clearly prefers full sun. Choose a location with at least 6-8 hours of direct sunlight daily. The plant also tolerates slightly moister soils than many other cranesbills.

This plant is excellent for borders, as underplanting beneath roses and other shrubs, and as groundcover for difficult dry spots. Due to its compact growth and weather-resistant character, it also works well in coastal gardens where salt and wind are normal.

Soil requirements

Bloody cranesbill is very adaptable to diverse soils. It thrives in moderate to poor ground and even tolerates dry, sandy soils well. Too much feeding leads to excessive leafiness. pH can be neutral to slightly alkaline (pH 6.0-8.0).

Optimal are well-draining soils. In clay ground add sand or coarse material. Once established extremely drought-tolerant - ideal for Mediterranean or dry gardens.

Watering

Bloody cranesbill is drought-tolerant after establishment. Water regularly in the first growing season, thereafter self-sufficient. Once established water only during extremely dry periods.

From May through October during bloom water regularly for sustained flowering, although it blooms even without extra water. Excessive water promotes leaf growth at the expense of flowers.

Pruning

Bloody cranesbill tolerates cutting back well. In August-September, following peak bloom, you can cut the plant back to 20-25 cm to encourage bushier growth and secondary bloom. This often extends the bloom period through October.

In spring (March) remove dead stems. Some naturally fall off after colder winters.

Maintenance calendar

March-April: Remove dead material, minimal feeding May-June: Peak bloom, water during dry spells June-July: Continuous flowering August-September: Cut back for secondary bloom September-October: Fall coloring and secondary bloom November-February: Plant withdraws

Winter hardiness

Bloody cranesbill is extremely hardy, tolerating temperatures to -25°C without difficulty. In temperate gardens it's absolutely frost-resistant. The plant withdraws in winter, but new growth appears early in spring.

No special winter protection needed. In very wet winters, drainage problems can occur, but this is rare in well-draining soils.

Companion plants

Bloody cranesbill combines well with:

• Rose (Rosa): colored combinations, shrub support
• Sage (Salvia): simultaneous bloom, different foliage form
• Dianthus (pink): same sunny preference
• Nepeta (catmint): blue-purple tones create nice contrast
• Lavender (Lavandula): Mediterranean character

Purchasing advice

Bloody cranesbill is very commonly available in garden centers year-round. Costs run around EUR 3-5 per plant. Best planting times are April-May or September-October.

The plant reaches full size in two growing seasons. For borders use 2-3 plants per square meter for dense coverage effect. For groundcover purposes up to 5-6 plants per square meter.
