If you want seeds just for gardening and don't like what you find in the seed packets, another alternative to stalking out neighbourhood plants is to buy a fruit or two from the grocery stands or the delivery service. Learn to haggle, it gives a 10% discount when you buy stuff and I think another 10% extra income when you sell stuff. On Finchwick Festival day, the grocery stands in Finchwick sell and buy items same way so you get better price for your produce. You can find rare plants for sale or harvest at the community markets lots too. I had sims play for tips in a lounge, they got to level up their skills and socialize and there was also the occasional free food. As a bonus you can harvest plants in that neighbourhood if you go there regularly. If you don't mind going through garbage, rummaging through the garbage bin gives broken appliances that when fixed can bring lots of money.
