Landscape Attributes Carman's Sacred Japanese Rush is a dense herbaceous perennial grass with an upright spreading habit of growth. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

Gardeners should be aware of the following characteristic(s) that may warrant special consideration; Carman's Sacred Japanese Rush is recommended for the following landscape applications; Planting & Growing Carman's Sacred Japanese Rush will grow to be about 18 inches tall at maturity extending to 24 inches tall with the flowers, with a spread of 24 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast 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 is quite adaptable, prefering to grow in average to wet conditions, and will even tolerate some standing water. This plant does not require much in the way of fertilizing once established. It is not particular as to soil type, but has a definite preference for acidic soils, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. Carman's Sacred Japanese Rush is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
