My thumb is turning Green

So, I like to garden. Mainly flowers. Actually, only flowers. Trees/bushes are boring - unless they are house plants. You have to have oxygen flowing. ha :) I seem to have trouble with house plants though. I kill them. They turn yellow, then brown, then little bugs start to fly around and then they smell. I planted this one maybe 3 weeks ago. I'll give it another month then out to the empty lot it goes.
When I retire, in like 35 years - wow, that is a long time - I want to have a huge ginormous garden and be featured in Southern Living Magazine. Ha! Fat Chance! Maybe for an article titled "Florida Woman's Green Thumb turns things Brown - What Not to do When Gardening".
I went to the neighborly Home Depot a few weeks ago and bought some flowers. My favorite flower EVER is the hydrangea. I bought a light purple - and I found out if you alter the acidity of the soil you can turn the blooms deeper blue. They were so pretty on my back porch. But guess what?!
They're dead. :( Blooms shriveled and brown. Oh, well, I still have a picture, right?

SO, let me take you through my "garden". :)
The flowers below are in the corner of our driveway. They're another one of my favorites! I have two identical pots on either corner of the driveway.

These guys are in the center of the pots above. Lantantas on the left and marigolds and something else - I forget - on the right.



So the flowers on the right and in the center are a kind of cactus! They have prickly thorns underneath the flowers. They are eye level to Bailey so I have to make sure she doesn't try to eat them!

And the red ones are geraniums, the bottom right another cactus and I think the yellow ones are impatients. These are in the left corner of the back porch.

That's it! :) Hopefully, I can keep them all alive! :)

P.S. The Peanut Butter dilemma was solved. Keep both natural and regular on hand at ALL times. :) Happy Tuesday!
