Fruits, nuts, berries, even asparagus! Although I've planted asparagus twice now and it died both times! I'll try again as I'm getting better now, but learned you can't just dig a hole and expect things to live.I have heard the term long term Gardening plant once harvest for 30 years with out replanting? Can this be done? If so with what food
actually, its the other way around. . . annual are only good for one year. Perennials can go on forever depending on what you are plantingthink along the line of Perennial and annual when it comes to flowers..chances are,not one Perennial flower will come back the next year.but a annual flower will come back each,for how many years.. foods are same way..take carrots and blackberries for example.you have to replant the carrots each year..but yet you dont have to with with blackberries..and of coruse theres fruit trees like lemon apple cherry and orange.they produce each year.
