Showcase Showcase as a Plant Encyclopedia?

I need a very simple layout for a plant encyclopedia. I bought the Showcase 4 years ago for a site I eventually abandoned, so I don't think I even got around to fiddling with it. I foolishly bought another add-on I thought would work for me, but it needs a lot of setup in the form of templates. I'm no coder and I find even simple html to be rather difficult to wrap my mind around.
So, what I need is a system that will allow me to have a picture of the plant, several drop-downs with pre-loaded choices and a text box to enter a simple description. Categories for navigation, perhaps a sub- category or two. I hope to eventually have hundreds if not thousands of entries so it needs to be very easy to set up and fast to use.
I think this is doable, question is, could your Nana do it?

 

You're a prince! Thank you.

 

OK, this will do. This will definitely do. Fairly intuitive, well thought out and makes a very nice page.
Nana approves!

 

Sure. Plant Guide
Only a few entries and still working on the site so it is what it is at this point.
