Types of Grass in Japan
Japanese grasses can add a different visual element to your landscapes. Depending on the grass, Japanese ornamental grasses can range in height from around 1 foot to nearly 7 feet in height. You can plant your grasses together in a pattern with taller grasses toward the back, mid-height grasses in the center of your bed and short ornamentals at the front. You also might consider mixing traditional bladed grasses with bamboo, which is technically just another form of grass. If planting grasses and bamboos, line the entire bed with a barrier to prevent the bamboo and grasses from becoming invasive.
