Question: Is the ivy eating the graffiti, covering it up or did it paint the streetart itself... ?

Last week I was walking around the streets in the city of Frankfurt and found this. I had to stay there for quite a while, it was just puzzling to look at it and in some way I was paralized for some time because I played with my mind cinema imagination. It´s an interesting view how the nature is connecting with the painting and around that spot there is the solid brick house architecture. Of course, there was just the house first, then somebody did the graffiti on the wall because it´s a cool spot and then the ivy started grewing from somewhere on the other side over the house and as well over it.

Sure?

Buuuuut...... what if?....

1.) The ivy is some kind of mutated ivy and as well a graffiti lover and started spraying something on the wall with its own chlorophyll?

...or..

2.) In the graffiti is some fertilizer, some special pheromones or just drugs which attracted the ivy and made it grew over it to absorb it?

...or...

3.) Somebody sprayed something ridiculous on the wall and somebody else didn´t want to see it all the time, but is as well just super-lazy about cleaning and painting, so he or she planted the ivy on the housewall and kept it growing to overgrow the graffiti.

...or...

4.) It just looks like ivy on the foto but actually the ivy and the green letters are just one very realistic streetart mural.

...or...

5.) It was just build like that from the beginning.

Feel free to add more possibilities what could have happened there in the comments :-)
