Planting & Growing
King of Hearts Bleeding Heart will grow to be about 8 inches tall at maturity, with a spread of 12 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 10 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 10 years. As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.
This plant does best in partial shade to shade. It prefers to grow in average to moist conditions, and shouldn’t be allowed to dry out. It is not particular as to soil pH, but grows best in rich soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture. This particular variety is an interspecific hybrid, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. 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.
King of Hearts Bleeding Heart 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.
