Branching summer annual with light hair on leaf blades and spikelets in several upright fingers. Grows to 40 inches high and spreads rapidly. Prefers moist or shaded mountain climates in the southern United States. Seeds remain viable for years. Invasive and considered a noxious weed in many eastern states and counties. Used as a packing material for porcelain in East Asia where it is native, which is how it is thought to have spread to North America.Important Info : Invasive.

LightConditions : Deep Shade
Deep Shade refers to the absence of sunlight, even during daylight periods.
Conditions : Partial Shade
Partial Shade is defined as filtered light found beneath trees with high limbs. Partial shade usually offers some protection from direct afternoon sun.
Conditions : Full to Partial Shade
Full shade means there is little or no light in the growing zone. Shade can be the result of a mature stand of trees or shadows cast by a house or building. Plants that require full shade are usually susceptible to sunburn. Full shade beneath trees may pose additional problems; not only is there no light, but competition for water, nutrients and root space.
Partial shade means that an area receives filtered light, often through tall branches of an open growing tree. Root competition is usually less. Partial shade can also be achieved by locating a plant beneath an arbor or lathe-like structure. Shadier sides of a building are normally the northern or northeastern sides. These sides also tend to be a little cooler. It is not uncommon for plants that can tolerate full sun or some sun in cooler climates to require some shade in warmer climates due to stress placed on the plant from reduced moisture and excessive heat.
WateringConditions : Moist
Moist is defined as soil that receives regular watering to a depth of 18 inch deep, does not dry out, but does not have a drainage problem either.
ProblemsWeeds : Preventing Weeds and Grass
Weeds rob your plants of water, nutrients and light. They can harbor pests and diseases. Before planting, remove weeds either by hand or by spraying an herbicide according to label directions. Another alternative is to lay plastic over the area for a couple of months to kill grass and weeds.
You may apply a pre-emergent herbicide prior to planting, but be sure that it is labeled for the plants you are wishing to grow. Existing beds may be spot sprayed with a nonselective herbicide, but be careful to shield those plants you do not want to kill. Non-selective means that it will kill everything it comes in contact with.
Mulch plants with a 3 inch layer of pinestraw, pulverized bark, or compost. Mulch conserves moisture, keeps weeds down, and makes it easier to pull when necessary.
Porous landscape or open weave fabric works too, allowing air and water to be exchanged.
