Category:

This is a cultivar in which the unusual nearly black foliage is the real attraction; delicate fern-like leaves will tolerate some foot traffic; neither flowers or fruit are particularly ornamental; great as a color accent in a rock garden

Landscape Attributes

Platt's Black Brass Buttons is a dense herbaceous perennial with a ground-hugging habit of growth. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

Planting & Growing

Platt's Black Brass Buttons will grow to be only 1 inch tall at maturity extending to 2 inches tall with the flowers, with a spread of 8 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 6 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 8 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 does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is not particular as to soil type, but has a definite preference for acidic soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. 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.
