Weeds often succeed because they out-reproduce other plants. Some are long-lived and may spread vegetatively, but others produce huge numbers of seeds.
|A few red stamens have accumulated in the gutter beneath these trees, but sometimes, if it's not windy, a thick red carpet can build up.|

A bit later in the summer, many of the old flowers themselves fall. I guess these are flowers that aren't setting seed; they no longer have a function and the plant can discard them. I don't know whether these are functionally male flowers or simply flowers that didn't get pollinated, but these form a pale grey-green carpet for a time.
