Rozanne Cranesbill

Discover More Information On Rozanne Cranesbill

Cranesbill (Geranium 'Rozanne') is a clump-forming perennial that produces showy violet-blue flowers with white centers from May to July, often continuing to bloom throughout the summer in cooler climates. This versatile plant thrives in full sun to part shade and is perfect for use in borders, rock gardens, or as ground cover. Known for its heat tolerance and long flowering period, 'Rozanne' also attracts butterflies while resisting deer and rabbits, making it a great choice for low-maintenance, pollinator-friendly gardens.

Plant Attributes

The Geranium 'Rozanne' (Cranesbill) is a robust perennial that forms mounds of deeply cut, deep green foliage with slightly marbled patterns. It grows 1 to 1.5 feet tall and spreads 1 to 2 feet, making it suitable for covering ground in sunny or partially shaded areas. The large, violet-blue, five-petaled flowers, which feature purple veins and a small white center, bloom profusely from late spring through summer and into fall in many climates.

With low water requirements and excellent heat tolerance, cranesbill is a reliable, long-blooming plant for USDA Zones 5 to 8. It tolerates rabbits and deer, making it a resilient option for gardens where wildlife might otherwise be an issue.

Landscape Use

Cranesbill’s beautiful flowers and dense foliage make it a versatile addition to many garden designs. Here are some common uses:

  • Ground Cover: Use cranesbill to cover ground in sunny or partially shaded areas. Its spreading habit makes it effective for filling gaps in borders or naturalized areas.
  • Borders: Plant along borders where its long bloom period and vibrant colors can provide continuous interest throughout the growing season.
  • Rock Gardens: Thriving in well-drained soils, cranesbill is an excellent choice for rock gardens where it can add both texture and color.
  • Cottage Gardens: Its old-fashioned charm and delicate flowers make cranesbill a perfect fit for cottage-style gardens.
  • Containers: Cranesbill can be planted in containers or window boxes, where its sprawling growth habit will spill over the edges, creating a lush effect.

Planting & Care

Cranesbill is a relatively low-maintenance plant that thrives in a variety of conditions. Follow these care tips for optimal performance:

  • Planting Location: Choose a site with full sun to part shade. In hotter climates, afternoon shade will help protect the plant from wilting in the heat. It performs best in moist, well-drained, organic soils but can tolerate a wide range of soil types.
  • Watering: Water regularly during the first growing season to help the plant establish. Once established, cranesbill is moderately drought-tolerant but prefers medium moisture. Keep the soil evenly moist after blooming to maintain healthy foliage.
  • Pruning: If the plant stops blooming during hot summer months, shear it back to rejuvenate and encourage a late summer or early fall rebloom. You can also trim side stems at any time to control the spread and shape.
  • Fertilizing: Fertilizing is not usually necessary, but applying compost or a balanced slow-release fertilizer in early spring can help support robust growth.
  • Dividing: To keep the plant healthy and vigorous, divide every 3-5 years in spring or fall.
