How do plants propogate?

What’s a good resource for learning how plants propogate?

I know some plants like Grasses (Poaceae) have stolons, which creep underground.

Others like Tamarisk (Tamarix) spread easily by wind.

What about plants like Black Nightshade (Solanum nigrum)? I’ve noticed it growing under lamp posts where birds sit, assuming berries are part of their diet?

Are there any good resources that give this information? What critter (if any) helps propogate specific plants? Is this just something learned by observing enough plants and animals?

If you have any unusual stories about how it works for certain plants or animals, please reply too!
