|What is quack grass? Is it purple?|
|Quackgrass has long, tapered blades around 1/3 inch wide attached to hollow stems. The plant is much more upright growing than crabgrass. The seed heads are single, upright stems, not branched like crabgrass. Quackgrass has a strong root system with white, fleshy rhizomes that spread out from the main plant, sending up new plants.
It is green, not purple.
