Copper Glow Shamrock's attractive small fan-shaped compound leaves remain chartreuse in colour with hints of coppery-bronze throughout the season on a plant with a mounded habit of growth. It features subtle yellow tubular flowers at the ends of the stems from late spring to early summer.
Copper Glow Shamrock is a dense herbaceous perennial with a mounded form. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
This plant will require occasional maintenance and upkeep, and should be cut back in late fall in preparation for winter. It has no significant negative characteristics.
Copper Glow Shamrock is recommended for the following landscape applications;
- Mass Planting
- Rock/Alpine Gardens
- General Garden Use
- Container Planting
- Hanging Baskets
Planting & Growing
Copper Glow Shamrock 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 8 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 5 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
This plant performs well in both full sun and full shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. 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. This is a selected variety of a species not originally from North America. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
Copper Glow Shamrock is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. 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.
