Pinegrass (Calamagrostis rubescens) is a versatile bunchgrass that brings texture, year-round structure, and weed control to shady and semi-shady landscape areas. Fine, arching blades form soft, flowing mounds that maintain a fresh green presence through spring and summer, turning warm golden-bronze in fall. Airy flower panicles rise above the foliage, adding movement and seasonal interest. Pinegrass is an excellent option for adding greenery in large, dry shade areas under pine, fir, spruce, oak, or aspen trees. Since it does spread by rhizomes and tends to be the dominant herbaceous plant in its ecosystem, it is best to pair it with shrubby plants that it will not outcompete, such as Creeping Oregon Grape, Wood's Rose, Oceanspray, etc. The more light Pinegrass receives, the faster it will spread, but it spreads more slowly in shady conditions. For this reason, we recommend Pinegrass in mature shade or woodland plantings (trees should be established so they are shading the area), naturalistic plantings, or for stabilizing slopes under trees. Using deep edging at the edge of the bed that blocks rhizomes can help prevent Pinegrass from spreading from its desired area into neighboring garden beds.
