Green clumps of tall fescue (left) as well as crabgrass and goosegrass (bottom right) are very conspicuous in this dormant Kentucky bluegrass lawn.
Small, round, green stems with swollen joints (nodes) can be seen at the center of this spreading crabgrass plant. Roots can form at the nodes allowing crabgrass to spread readily.
Crabgrass seedheads are distinctive from that of goosegrass.
Goosegrass stems develop a white, flattened rosette at the plant's center.
Goosegrass seedheads have two flattened rows of seeds on individual spiklets.
Tall fescue is wider bladed and more drought resistant than Kentucky bluegrass or perennial ryegrass forming clumps in a mixed stand.
Tall fescue is not likely to have a seedhead at this time of year and is often red to purple at the base of the stem.
