As defined a weed is a plant that grows where you don't want it to. In that case my greenhouse is full of weeds!
Several Cyclamen species have a habit of seeding into the sand plunge, or seed pots or pots of other Cyclamen species.
Cyclamen persifum is one of them - I usually leave them out of laziness and because quite often they outlive a pot's original occupants.
Also with Cyclamen you do get some variation from the parents - this one has a lovely pure pink shading - a bit different from other plants I have.
As an added bonus many of these self sown seedlings are quite vigorous having undergone some natural selection to my greenhouse environment and routines.
