You can grow a decent crop of bananas in Maine, if you are talking peppers. Capsicum annuum is not a difficult plant to grow: full sun, rich soil and adequate moisture usually yields good results. The Sweet Banana variety, which was an All-America Selections Bronze Medal winner in 1941, has long been a reliable pepper. It is not a hot pepper, although the Hungarian Wax pepper that looks similarly is. The waxy yellow peppers mature to red if left long enough on the plant and can be used fresh, cooked or even pickled.
