What is the definition of Periods Seeds?

"Periods seeds" is a whimsical term that refers to the tiny, unassuming seeds of plants that we, humans, have planted in our daily lives. You know, the seeds from dandelions that sprout through cracks in sidewalks, or perhaps the minuscule ones from the seeds we eat in breakfast cereal. They're like our secret weapon of plant propagation, but instead of turning into leafy greens, they're more likely to sprout into pesky weeds in our own backyards.

Here's an unsettling example sentence: "I planted 10 period seeds for my indoor jungle, but now I'm questioning if I should call them 'y' plants or just 'the seeds that are starting to decide to take over my living room.'"
