Could I have a green thumb?

I've still been scrapping away, although I haven't posted here in several weeks. And I'm still working on my little patio garden.  Apparently, gardening is addictive.  I've got it really bad.  I can't go anywhere without looking at plants and wanting to buy them.  Yesterday I planted the last of the plants I've bought, and told myself, "No more!"  I can play with my seeds, but no more buying plants.

Right now I'm playing with some grass seeds.  I put cat crass/oat seeds in some hanging planters, I have some wheat grass that I'm going to use to fill in some areas of my herb planters.   And I have some blue fescue  that I read is a decent option for indoors.  I really want some more indoor plants, so I hope this grass works out.

There is so much to learn about gardening.  I have trouble even with the terms "annual" and "perennial."  It's the word annual that throws me.  Annual ... yearly ... oh, it must come back each year.  That's how I want to think.  But I think I have to go more along the lines of: Annual ... once per year ... oh, it just grows once. 

So much to learn, and I have learned a little.  One of the plants I started from seed (I think it was from a seed pack called Butterfly Flower/Swamp Milkweed) was starting to get yellow spots.  I did a little reading, and decided to try some fertilizer on it.  I did, and after a week or two the yellow spots started to go away! Boy, was I proud after that.  I have now fertilized all of my pots and planters and plan to keep doing that once per month.

Here are some pictures from my little patio garden.
