Porcupine Grass (Miscanthus Strictus)
The Most Unique Ornamental Grass
Porcupine grass is a fast-growing ornamental grass with thin, rigid leaves adorned with horizontal yellow bands and an upright columnar habit.
This perennial grass grows in clumps and produces pinkish copper flowers in early fall that rise over the foliage to an overall height of 8-9 feet, but requires a long hot growing season and moist well drained soil to flower.
Flowers turn to silvery plumes in fall. Late foliage will protect the crown during winter so do not cut back until spring. Then cut to 4-6 inches above the ground, before the plant starts to grow. Divide only in spring when new growth starts.
You'll get less vigorous flowering in too much shade. Use it as a border specimen, hedge or screen, as a tall vertical corner, around water features, in wild or naturalized gardens, or in containers. Deer resistant and moderately drought tolerant.
