Answer: The lovely plumes that pampas grass develops is where the seeds are produced. To keep accidental plants from sprouting, you can cut the plumes down about 3 weeks after they emerge, and before the seeds mature and are spread by the wind. Other plants with similar foliage include yucca, kniphofia (red hot poker), and some of the larger ornamental grasses such as Muhlenbergia (bamboo muhly), Phalaris (ribbon grass) and Stipia (feather grass). Hope these suggestions help you choose just the right plant for your landscape!
