PORCUPINE GRASS
Miscanthus sinensis 'Strictus', widely known as Porcupine Grass, is a bold, architectural cultivar famous for its stiffly upright habit. Unlike its cousin 'Zebrinus' (Zebra Grass), which has a relaxed, arching form, 'Strictus' grows in tight, vertical columns that resemble a bundle of quills - hence the name. It typically reaches 5 to 6 feet tall and is instantly recognizable by the vivid horizontal gold bands that "spot" its olive-green blades. In late summer or early autumn, it produces reddish-bronze flower plumes that rise above the foliage and gradually mature into soft, silvery-tan tufts.
Caring for Porcupine Grass is incredibly easy, making it a perfect choice for gardeners who want a "statement plant" without the fuss. It performs best in full sun, which is necessary to keep the stems rigid and the golden variegation sharp; in too much shade, the plant may lose its upright posture and lean. It is highly drought-tolerant once established and can thrive in various soil types, including heavy clay, provided the area is well-drained. Because it is a deciduous grass, it will turn a warm tan in winter. Maintenance is a simple once-a-year task: in late winter or very early spring, cut the entire clump back to about 6-8 inches from the ground before the new "quills" emerge.
