Sidewalks and driveways, especially brick or pavers tend to heat up and retain that heat so the plants germinate earlier.

Poa annua L. is a highly variable plant from its evolutionary origin as an allotetraploid hybrid between Poa infirma and Poa supina (Figure 1)..

Poa annua is the only flowering plant species that has established a breeding population in the maritime Antarctic, through repeated anthropogenic introduction. The first appearance of this species in the Antarctic was observed in 1953. Annual bluegrass inhabits mainly anthropogenic sites, but recently has entered tundra communities Poa annua is a prolific seed producer, producing upward of 350 seeds per plant per year. Seeds remain viable for up to 16 years in the soil, so there may be up to 110 viable seeds in the soil. Poa occupies almost every niche on a golf course, but superintendents are usually limited to only focusing control methods on greens, leaving the rest of. If all Poa annua were a true winter annual, we could control it with preemergence herbicides, but much of it is a weak perennial that can survive the summer. Even where it survives, it is still an annoyance in sports turf because of its difference in color and texture from other grasses There are several sub species of Poa annua, old established push-up greens like here at Phoenix are 95% Poa, but I would have a guess that 90% of that is Poa annua var reptans which is the preferred species. This so called annual actually grows as an annual, a biennial and a short lived perennial Poa trivialis, on the other hand, rarely produces a seedhead when mowed (photos). Control of Poa annua and Poa trivialis in lawns is difficult, if not impossible and it may not be economically feasible or practical. Control of Poa trivialis is most effective with a non-selective herbicide followed by reseeding
