This is a relatively low maintenance plant, and should be cut back in late fall in preparation for winter. It has no significant negative characteristics.
Jack Frost Bugloss is recommended for the following landscape applications:
Planting & Growing
Jack Frost Bugloss will grow to be about 12 inches tall at maturity extending to 16 inches tall with the flowers, with a spread of 18 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 14 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. 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.
This plant does best in partial shade to shade. It requires an evenly moist well-drained soil for optimal growth. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture.
Jack Frost Bugloss 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 and foliage 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.
