I have always had some concern about the (somewhat) recent surge in ornamental grasses in the horticulture industry. I have been following several species over the past few years that have been of particular concern for their "weedy" potential.
Nassella tenuissima, Mexican Feather Grass, is one of the species that has grabbed my attention. It seems to be the new trend in covering large expanses with grasses, in park and streetscape settings (and can even be found on some roof gardens). I will admit that there is something spectacular about its fine textured plumes dancing in the breeze, and it is quite drought tolerant in our California climate. However, the nursery industry seems to be more concerned with making a buck than considering the invasive potential of this species. And designers seem to be either ignorant or naive about the invasiveness of this species.
