More Information
LoreMexican feathergrass often self-sows abundantly and may spread out of its designated place in the garden. It is an extremely vigorous grass, and can crowd pasture species as well as native grasses in coastal areas. In Argentina, where Mexican feathergrass is native, it is regarded as an unpalatable grass (Moretto & Distel 1998). The grass forms indigestible balls in the stomach of livestock and, Mexican feathergrass can become dominant under continual heavy grazing pressure with a low frequency of high-intensity fire (Distel & Boo 1995). Monrovia does not ship this grass to California.
Average Size at MaturityForms airy clumps 12 to 24 in. tall and as wide; 30 in. tall in bloom.
Bloom TimeSummer
Design IdeasBeautifull grown in masses, this is a candidate for rock gardens, dry streambeds and next to landscape boulders. Grow as a single accent or in a small cluster among other drought- and heat-resistant perennials for unique color and texture variation. Excellent choice in Mexican ceramic pots for an artistic statement in Santa Fe-style garden. In California, substitute dwarf fountain grass (Pennisetum alopecuroides 'Hameln'), Blonde Ambition blue gamma grass (Bouteloua gracilis), or prairie dropseed (Sporobolus airoides) for a similar effect in the landscape.
