The porcupine grass is a cool-season grass forming a basal clump of leaves and tall, slender flowering leafy stems; it flowers in the summer with beautiful panicles that are dangling graciously in the wind.
The fruits are accompanied by particular, long awns; when the seeds inside became mature, fruits detach and fall to the ground, their awns twist and literally drill the seed into soil.
It can be used in groups or interspaced in wildflower gardens, or in combination with warm grasses which are starting to grow later in the season. In the fall, the porcupine grass takes a whitish-silvery appearance.
Germination: sown in late fall or very early spring. The seeds are large therefore need to be planted deep enough in the substrate.
