My favorite tree is the fig. I bought one from the Louisiana agricultural department. They actually raised a plant specific to the area. It puts on figs twice a year.
My family's favorite is the blueberry but I think everyone likes blueberries.
The blackberry bush makes enough for me to flavor a tea or smoothie. Only I eat those.
The muscadine vine tries to take over the world. It needs lots of manicuring but it makes some many grapes. Great for wines and jellies.
What do you grow and how do you use it?
