I've found only blueberry and mushrooms in the new world. You probably know that you need to spend a certain amount of time in the hood for crops to spawn on community ground. Same in other worlds, hang out a day or two in the hood to find stuff to harvest. That said, my impression is there are fewer plants in Henford-on-Bagley than in worlds like Willow Creek and Oasis Springs. Your sim might be better off by purchasing a few fruits/veggies at the stall, to plant.
PS: Maybe you can visit a neighbor and harvest a plant there. Neighbor might get upset, but probably not until you got some crops into your inventory.
