We have received many questions on this identification of what maybe growing in your lawn. What you see today is known as Kentucky Bluegrass (KBG), which is common in most Virginia lawns. Most lawns in our area are a mixed stand of Tall Fescue and KBG. In fact, our seed blend is a combination of these two grass types. A lawn that is properly mowed at 4 inches will allow the KBG, and sometimes even the fescue, to produce a seed head. This is completely normal and it’s the natural reproductive phase of the grass plant. After a few weeks, the seed stalks will diminish, and the lawn will even-out. 

We should not confuse KBG with Poa annua. Poa annua is starting to yellow as warmer temperatures approach. Remember, this is an annual that will completely die this summer. The KBG (Poa pratensis) is a desired perennial that will persist throughout the season. It will not be yellowing and is typically scattered throughout the lawn where Poa annua is seen along the driveway and sidewalk edges. Also, Poa annua is shorter and “clumpier,” while KBG has more upright in growth.
