How to Get Ornamental Grass Seeds From Already Grown Plants

Ornamental grasses are made up of not only true grass but also grasslike plants including rushes, sedges and bamboo, according to Colorado State University. Ornamental grass adds height and interest to a yard. Many are colorful or have interesting flower stalks when in bloom. Also, some ornamental grass is drought-tolerant, which makes caring for it easy. Ornamental grasses produce seeds after they flower so growing grass usually produces seed if grown in full sun.

  Place the paper bag over the flower stalk and cut the stalk from the grass with the scissors. Hold the end of the stalk sticking out of the bag and turn the bag right side up, so the flower stalk is upside down inside it. Shake the stalk while inside the bag to loosen the seeds. The seeds will fall into the bag. If all the seeds don't fall, run your hand over the stalk, pushing seed into the bag.
