Seconded BlueberryRush! Save your seeds in your peppers, tomatoes, cucumbers, melons, fruits, everything you like to eat and plant them!
For flowers, do you have Dollar Tree in Virginia? They sell packets of both flower and veggie seeds 4/$1. I load up at this time of year. And at the end of the season, places sell their seeds for next to nothing. I loaded up in November for $.10/packet.
I would also recommend something like this. $16 gets you a TON of all different kinds of awesome fruit and veggie seeds. I bought that bag two years ago and it seems like I haven’t come close to making a dent.
