Plant Spreads

Do planets like the Lupine flower spread?

 

I created farmland and I just saw a random Horsetail plant spawn on it.

Tilled soil will do that, in fact it's one way to get horsetail although you can't manage their growth.

In terms of flowers, I could be completely wrong here, but over several in game years I never noticed any of the flower areas "drifting over time". So for me, the answer I would give is "no".  Although grass will regrow in areas that have burnt.

They don't. Maybe some day they will. As @Broccoli Clock already noted, farmland that isn't planted can spawn grass and horsetail as weeds, but won't spawn new flowers or other plants, at least not without mods. The only plant that actually spreads naturally by itself is grass, but even then it's limited to growing atop exposed dirt and clay.

A sad thing is that if a biome does not already have grass growing there, grass will not spread to dirt blocks placed in that biome. So you can't introduce grasslands into a desert or gravel biome. If you find a patch of grassy dirt, don't remove it because if you do it is gone forever.

Grass does need a nearby block to spread from.  How nearby is nearby, I don't know.  I don't think it needs to be contiguous like TOBG.

I think if the gravel is in a biome where there is grass, it might spread, but if it's in a biome without grass, you can wait until the end of the world and grass will not spread to a dirt block placed there even if it's adjacent to 50 grass blocks in the neighboring biome. 

I just had to give up raising an area by covering a small patch of gravel in the middle of grass with dirt because the grass will not grow there.
