Fruit and vegetable names! I' m a big fan of food based names for pets...and virtual pets.
All my horses in D and D and in on line role playing games were named after food. Usually baked goods so I'm not as healthy as you WhoDat
I replanted a lot of the garden and every time I'd plant something I'd try to remember it's name. I'd go around watering them until they were established and repeat their names as I went. So, if it had a label, I probably know the botanical name

. (Then they go and change the dang name! I prefer Eriostemen to Philotheca!
