Landscape Attributes

Yaku Jima Dwarf Maiden Grass is an herbaceous perennial grass with a mounded form. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This plant will require occasional maintenance and upkeep, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting birds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Yaku Jima Dwarf Maiden Grass is recommended for the following landscape applications;

• Mass Planting
• Hedges/Screening
• General Garden Use
• Groundcover
• Container Planting

Planting & Growing

Yaku Jima Dwarf Maiden Grass will grow to be about 3 feet tall at maturity extending to 4 feet tall with the flowers, with a spread of 3 feet. It has a low canopy with a typical clearance of 1 foot from the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 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 does best in average to evenly moist conditions, but will not tolerate standing water. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil pH, but grows best in rich 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.

Yaku Jima Dwarf Maiden Grass is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used 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. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
