Growing Garden

I am not a gardener. At all. Honestly, I don't enjoy the dirt. I don't enjoy the way it feels and how it always gets under my nails. Now paint and spackling don't bother me. Weird huh? 

Anique always wants to garden. I send her to both her Nana's houses to get her fix. She goes to the garden show with my mother-in-law. And over the last couple of months they start sending plants and seeds home with her. 

So now I'm desperately trying to make sure nothing dies. My window is full of plants. She has escarole growing on the deck. What is that? How do we harvest it? And what do I do once it's harvested? 

Suggestions? Back to the Internet...there must be a YouTube video somewhere on escarole...
