The Mystery of the Mystery Plant

We throw any vegetable scraps (e.g. carrot peels, rotten fruit, etc …) directly into the garden to rot away with other yard waste and every year we get mystery plants. Mystery plants fall into a strange gray area as they are not weeds in the familiar sense, but they are plants not intended which grow from seeds thrown out from the kitchen. Given that it can be tricky to start plants from seed, there is a temptation to want to let them grow if for nothing other than to see what they are even if they are out of place. Cucumbers and melons are the most common mystery plant, but tomatoes and potatoes have also made previous appearances. One year, a grape vine even managed to sprout which we later transplanted to a nicer spot near the backyard fence.
