Ornamental Features

Pony Tails Mexican Feather Grass features airy plumes of gold flowers held atop the stems in mid summer. Its attractive threadlike leaves are green in color. As an added bonus, the foliage turns a gorgeous harvest gold in the fall. The gold seed heads are carried on showy plumes displayed in abundance from late summer to late winter.

Planting & Growing

Pony Tails Mexican Feather Grass will grow to be about 20 inches tall at maturity, with a spread of 24 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America. It can be propagated by division, however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
