Muhlenbergia, Powderpuff Grass


1. Light/Sun Exposure - Full to part sun.

2. USDA Hardiness Zones - Winter hardy in-ground in 6-10. Hardy with protection in 5 and colder.

3. Planting Distance - 2 to 3 feet apart in ground.

4. Mature Height/Spread - 2 to 3 feet tall with a similar spread.

5. Bloom Time - Late summer/fall.

6. Planting Instructions - 

Important:  Thoroughly rehydrate the plant and its surrounding soil before planting so it may properly adapt to its new location.  We recommend submersing the root zone of the plant in a container of water for 2-3 minutes while you prepare for planting.


  1. Remove and discard the clear plastic bag from around the plant.


  1. Dig a hole twice as wide and twice as deep as the plantable plug.  Partically backfill the hole with soil and place the plant into the hole.  The top of the plug should be level with the ground surrounding the hole.  Refill the hole with soil, firming the soil around the plant with your fingers.  Check to be sure the plant is not planted too deeply.  If it is, raise the plant carefully and refirm the soil.


  1. Water thoroughly.



Pink or White Powderpuffs Grass (Muhlenbergia capillaries) will provide up to 12 months of decorative value in everyone's landscape.  Outstanding performance even in the unforgiving heat and drought of the Southern garden. A very undemanding grass variety, which is long lived, very low maintenance and which is valued by discerning gardeners for its color and texture.


Although these plants will perform well in average garden soils of all types, we recommend having your soil tested periodically by your local County Extension Office ( or call 1-800-333-4636). These tests can determine if the soil needs any amendments to enhance your plants' growth and performance.  See below for our recommended practice to improve your soil without any additional testing:

1. Spade or till the soil to a depth of 12 to 18 inches.

2. To provide nutrients and improve drainage, add organic matter to your soil by mixing in a 2 to 4-inch layer of dehydrated manure, garden compost, shredded leaves, and/or peat moss.

3. After active growth begins, periodically feed with Cottage Farms' water soluble Carefree Bud-N-Flower Booster. Plants in containers need more frequent watering and feeding, especially when in active growth and bloom.


Watering - Adequate and consistent watering is essential during the plant's first year in your garden.  Infrequent, long soakings of water that thoroughly saturate the soil surrounding the root zone are more effective than frequent light applications of water that may wet the top of the soil only.  

Due to individual plant needs, geographical and environmental conditions, a specific watering schedule is hard to define; however, as a rule of thumb you should not allow the soil to completely dry out.  During periods of drought and extreme summer heat, you may need to water as often as every day.

Overwatering can be as damaging as under watering.  Be sure that the area surrounding your plant does not become a water-holding bog and that there is adequate drainage to move excess water away from the plant.  See Soil Preparation for tips to improve drainage.

Mulching - Apply a 2 to 4 inch layer of shredded bark, compost or other organic mulch around your plants to promote moisture retention, maintain even soil temperatures, and to discourage weed growth.

Weeding - Keep the area around your plants free of weeds. Weeds compete with all plants for food, water and light. Walk around the garden periodically and pull weeds, including the roots, as soon as you see them. Mulch also assists in keeping weeds down.

Grooming - Muhly grass requires very little pruning. When Spring temperatures begin to arrive, remove the winter mulch from in-ground plants and move containers back into the garden.  Prune the foliage down to 2” above the soil. New growth will quickly sprout from the roots and provide a more spectacular display year after year.

Feeding - Feed your plants once every 2-3 weeks during the growing season with a water-soluble fertilizer such as Cottage Farms' Carefree Bud-N-Flower Booster.  Discontinue feeding after September 1st so your plants can harden off for winter dormancy. Resume fertilizing when new growth appears in the spring.

Winterizing -

Zones 6-10: Little to no winterizing is required in zones 10-6, though a heavy layer of organic material such as bark or mulch over the root area will enhance the plant's cold tolerance. Let the foliage and plumes remain on the plant throughout the season to provide visual interest in the winter garden.

Zones 3-5: Careful forethought to the plant's winter needs should be made when deciding where in the ground to grow Muhly grass.  Protection from cold, northern winds and freezing rains is essential.  While a thorough watering in late fall and a heavy layer of organic material such as bark or mulch over the root zone will greatly enhance the plant's cold tolerance, the greatest benefit may come from planting in a container that can be moved into a protected, non-freezing area such as a garage or basement.  Containers moved out of the elements should be watered well every 7-10 days.

All Zones: When Spring temperatures begin to arrive, remove the winter mulch from in-ground plants and move containers back into the garden.  Prune the foliage down to 2" above the soil.  New growth will quickly sprout from the roots and provide a more spectacular display year after year.Grasses do best if you don't cut them back in the winter.  In northern locations that experience freezing winter temperatures, the plants will die back to the ground and go dormant for the winter. They will sprout from the roots in the spring and be even more spectacular with each passing year.  After the ground has frozen, apply a winter mulch of evergreen boughs, straws or leaves to prevent lifting of the plant's roots during alternating periods of freezing and thawing.  


CAUTION: Not all plant material is edible. Though most plants are harmless, some contain toxic substances which can cause headaches, nausea, dizziness, or other discomforts. As a general rule, only known food products should be eaten. In case of ingestion, please contact your local poison control center at once and advise them of the plant ingested. Keep out of reach of children.
