outstanding ornamental grass has leaves pleated like palm foliage.
The clumps, if well fed, can grow to 6' wide and 3' high. The selections
of this species grown from seed collected in high-elevation, cloud forest
habitats in central Mexico grow very well in San Antonio and Austin.
They will often self-sow and re-sprout from below after all but the coldest
winters. S. poiretiana is significantly more cold-hardy than Setaria
palmifolia, the Asian species of Palm Grass usually sold in the U.S.
Grows best with shade in the afternoon. And, it looks best if given
a deep watering every week during a dry summer (though it needs less water
in more shade). Mulch deeply in late fall to provide winter protection.
(Feed with 1 to 3 Agriform
2-year fertilizer tablets at the bottom of the hole at planting time.)
