Lancastriense Bloody Cranesbill

Lancastriense Bloody Cranesbill (Geranium sanguineum var. striatum 'Lancastriense')

Lancastriense Bloody Cranesbill is a tough, low groundcover that quickly fills in and makes borders look finished with very little effort. Also known as Lancastriense Cranesbill, it spreads into a dense mat that helps suppress weeds and soften bed edges in sun or part shade. In late spring into summer, it adds a steady run of pale pink flowers with darker veining that read as delicate up close but strong in a drift. Once established, it handles dry periods well, making it a dependable choice for busy landscapes.

Distinctive Features

This hardy geranium forms a compact, mounding to gently spreading carpet of deeply lobed green foliage that often develops red to bronze tones in fall. Flowers are cup-shaped and soft pink with darker pink to reddish veining, blooming most heavily from late spring into early summer with lighter flowering that can continue into summer. The habit stays low and tidy, making it easy to use as a front-of-border groundcover without constant trimming. Its durability and dense growth make it especially useful for tying plantings together and reducing open soil.

Growing Conditions

• Sun: Full sun to part shade, with part shade helpful in hotter regions for cleaner foliage.
• Soil: Average, well-drained soil is best, and it tolerates a range of soils as long as drainage is reasonable.
• Water: Medium moisture during establishment, then low to medium water, watering during extended drought for best bloom and foliage.
• USDA Zones: USDA Zones 4 to 8.
• Drainage: Avoid persistently wet sites to support healthier crowns and longer-lived plants.
• Resilience: Tolerates drought once established and holds up well in challenging, competitive planting areas.

Ideal Uses

• Focal Point: Plant a broad ribbon along the front of a bed so the pale pink veined flowers create a clean, close-up highlight in late spring.
• Groundcover: Use to knit open soil into a weed-suppressing mat that keeps borders looking finished.
• Edging: Line paths and bed fronts for a low, tidy border that softens hard edges.
• Rock Gardens: Tuck into sunny, well-drained pockets where the low habit fits naturally and blooms read clearly.
• Underplanting: Weave under shrubs and open-canopy trees to connect plant groups and reduce maintenance.

Low Maintenance Care

• Shearing: Trim lightly after the main bloom flush to refresh foliage and keep the mat neat.
• Watering: Water during prolonged drought, especially in full sun, to maintain stronger flowering and greener foliage.
• Mulching: Mulch lightly to conserve moisture and reduce weeds, keeping mulch off the crowns for airflow.
• Division: Divide every few years if you want to rejuvenate vigor, control spread, or expand plantings.
• Cleanup: Remove tired leaves in late winter or early spring so fresh growth emerges cleanly.

Why Choose Lancastriense Bloody Cranesbill?

• Weed Suppression: Dense, low growth covers soil quickly and helps crowd out weeds.
• Soft Pink Bloom: Pale pink flowers with darker veining add refined color from late spring into summer.
• Fall Color: Foliage often shifts to red and bronze tones, extending seasonal interest.
• Mature Size: Typically grows about 6 to 12 inches tall and spreads about 12 to 24 inches wide.
• Deer: Often considered deer and rabbit resistant, though browsing pressure can vary by location.

If you want a durable, low groundcover that flowers well and keeps working through the season, Lancastriense Bloody Cranesbill is a smart choice. Plant it in well-drained soil, keep moisture steady while it establishes, and shear once after bloom for a fresh look. Over time it forms a cohesive carpet that makes planting beds feel more connected and complete.
