Beautiful double flowers in shades of rose and purples are featured on mounds of deep green foliage; fast and vigorous growth, excellent for border, bed and container planting; low maintenance-remove spent flowers to encourage more blooms
Double Cranesbill has masses of beautiful violet flowers at the ends of the stems from late spring to early fall, which are most effective when planted in groupings. Its deeply cut lobed palmate leaves are emerald green in colour. As an added bonus, the foliage turns a gorgeous orange in the fall. The fruit is not ornamentally significant.
Double Cranesbill is an herbaceous perennial with a mounded form. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
This is a relatively low maintenance plant, and should only be pruned after flowering to avoid removing any of the current season's flowers. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
Double Cranesbill is recommended for the following landscape applications;
- Mass Planting
- Border Edging
- General Garden Use
- Container Planting
Planting & Growing
Double Cranesbill will grow to be about 18 inches tall at maturity, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 20 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.
This plant does best in full sun to partial shade. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
Double Cranesbill is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception.
