ELI5: How does grass reproduce?
gpt
Wild grasses are flowering plants (their flowers aren't around all the time, but they vaguely look like wheat flowers, if you're unfamiliar) so they reproduce the same way other flowering plants do - that is, sexually. But some grasses can reproduce through vegetative propagation, which basically means that new grass can grow nearby after popping up from an expanded underground root system. That's how a lot of lawn grass reproduces.
