Yaku Jima is a type of dwarf Maiden Grass, this maiden grass is also called the Japanese silver grass. It is a clump-forming grass that can be found throughout the United States. The dense clump of upward-arching leaves and stems give it a rounded, fountain-like appearance. The leaves have tapered tips with silvery midribs. By mid-fall, the foliage transforms into a beautiful shade of orange and yellow. Once winter arrives, the colors fade into a beige hue.
Along with the brilliant foliage, the Yaku Jima produces feathery red to pink flowers from late August to October. As the seeds mature, the flower panicles turn into a beige color. The foliage and flowers retain their shape and beige tones throughout the winter. This maiden grass provides plenty of winter interest, especially as it peeks out from the freshly fallen snow.
With its delicate and subtle texture, you want to use this maiden grass throughout your landscape. When you place several of the Yaku Jima maiden grasses together, you can create an impressive mass planting. The narrow leaves are the perfect way to add some airiness to your space. When the colors change on the plant, those spaces shine for the fall season.
The Yaku Jima can also be used for a hedge or screen. The dense clumps provide plenty of texture and color contrast to shrub borders and mid-sized perennial beds. If you have issues with semi-shaded spots in your garden, consider this maiden grass for those spaces. It doesn’t need full sun to grow long and thick in your landscape.
