Seedling
4-6 weeksYoung plants with small, delicate lobed leaves and weak root systems; typically 1-2 inches tall
Keep soil consistently moist but not waterlogged. Provide bright light. Protect from direct sun and strong winds until established.
Vegetative
6-12 weeksRapid leaf expansion and stem development; plants form bushy mounds with increasingly dissected foliage; roots strengthen
Space properly to allow air circulation. Water moderately. Reduce frequency as plant establishes. No fertilizer needed in average soil.
Flowering
6-8 weeks (spring-early summer)Abundant five-petaled magenta-pink flowers with darker veining appear at stem tips; flowers are 1 inch across and attract pollinators
Deadhead spent flowers to encourage continued blooming. Ensure consistent moisture during peak bloom. Flowering may slow in extreme heat.
Post-Bloom & Seed Set
4-6 weeksFlowers fade and are replaced by distinctive seed pods resembling a crane's bill (hence the common name). Foliage may develop reddish tones.
Allow some seed heads to remain for wildlife; deadhead others to prevent excessive self-seeding if desired. Reduce watering.
Dormancy/Fall & Winter
4-5 monthsFoliage persists but may turn bronze or reddish; plant enters semi-dormant state in cold climates; deciduous or semi-evergreen depending on hardiness zone
Minimal water needed. No fertilizer. In zones 3-5, cut back dead foliage in early spring. Mulch lightly in colder regions if desired.

Harvest Tips
Bloody cranesbill is an ornamental perennial and is not harvested for food. Cut flowers can be enjoyed indoors—pick in early morning when stems are turgid. Collect seed pods in late summer if desired for propagation. To propagate, divide established plants in spring or fall, or collect and sow seeds in fall or spring.
Fun Facts
- 🌱 The name 'cranesbill' comes from the distinctive seed pod shape, which resembles a crane's long, pointed beak and splits explosively to disperse seeds up to 20 feet away.
- 🌱 Geranium sanguineum is not a true geranium (genus Geranium) but is often confused with zonal geraniums (Pelargonium); true geraniums are cold-hardy perennials while Pelargoniums are tender annuals in most climates.
- 🌱 This species has been grown in European gardens for centuries and was a favorite of cottage gardeners; its hardiness and low maintenance make it a testament to why traditional plants endure.
