The Q&A Archives: Potato Plant Flowering

Question: I am growing red skin potatoes which I planted in early May. I harvested 6 plants already and they look great in color, size and taste great. My question is on 6 of the remaining 18 plants still growing, thier are little (what looks like cherry tomatoes) growing on the plants. Have any ideas what these are? I have a digital camera and can send you a picture of one if you would like. I have been growing potatoe plants for several years and have never seen this.

Answer: Tomato and potato plants are both members of the nightshade family so their leaves and their blossoms appear similar. But, the potato plant produces fruit in the form of tubers underground and the tomato plant produces fruit on the top of the plant. The round, green tomato-looking things on the tops of your potato plants are seed pods. They will grow to about one-inch in diameter but they will never turn red and they are not edible. The blossoms on potato plants simply indicate that tubers are beginning to grow underground. Leave the seedpods alone and harvest your potatoes after the foliage dies down.

Hope this clears up the mystery for you!
