That depends on what Harvest Moon game you are playing.
Tomato, Corn, Onion, and Pineapple are the basic Harvest Moon Summer crops.
But not all the Harvest Moon games have the same crops.
Trees don't, but crops can. For example: Turnips grow in the spring. When it turns to summer, they go brown and die. You cannot plant more, but you can plant any other seeds that grow in the summer.
Summer
Once you have the basement unlocked and built, placing the sun onto the sun box will change the season of the basement. For example, putting a summer sun in the basement makes only summer crops grow in the basement. In this way, you can grow crops even in winter.
