This plant is problematic and alternatives should be considered. Please see the suggestions in the left-hand column.
Maiden grass, in the true grass or Poaceae family, is the most common ornamental grass. Having originated in Asia, this grass has numerous cultivars, although some are considered weedy and invasive in the southeastern United States. It is seen most commonly along roadsides and disturbed areas.
This clumping grass grows up to 12 feet tall in all types of soil and in all but the shadiest of environments. Wind-disseminated seeds increase the invasive nature of some cultivars that, once established, are difficult to eradicate. Frost-killed portions of maiden grass can remain standing throughout the dormant season because the buff-colored foliage, stalks, and hairy white fruiting heads have great fall and winter interest and the seeds are particularly attractive to song birds.
Foliage should be cut down in late winter or early spring before, or just as, new blades begin to appear. Heavy mulching helps prevent seed germination and can keep this plant from becoming invasive. It is relatively pest and disease-free, is highly salt tolerant, and also resistant to damage by deer.
There are many cultivars and some are less likely to self-seed than others. Look for cultivars that do not flower until September or October, or cultivars that are bread to be less fertile like Bandwidth™ or My Fair Maiden™.
Quick ID Hints:
- Forms erect clumps
- Terminal inflorescence is 8-inch long, finger-like racemes
Fire Risk: This plant has a high flammability rating and should not be planted within the defensible space of your home. Select plants with a low flammability rating for the sites nearest your home.
Insects, Diseases, and Other Plant Problems: This plant can become weedy and invasive. Listed as invasive by the NC Invasive Plant Council. Some cultivars have shown good resistance to phytophthora. See Phytophthora Root and Crown Rot in the Landscape.

- Flower Description:
- Inflorescences a terminal panical of spikelets that unfurl atop the central vertical stalks, and differ among the numerous cultivars in terms of their time of emergence, color, separation from the upper foliage (well-separated or immersed within it), and Winter persistence. Secondary axes in elongate, finger-like racemes that grow up to 8" long. Spikelets are paired, less than an inch in size, lanceolate, and with long silky hairs basally. As fruits develop, axes develop hairs that spread for seed dispersal.
