A flower quiz
For Garden Bloggers' Bloom Day and the end of school, here's a quiz: what do all these flowers have in common?
From the top: petunia, pepper, potato, nicotiana, tomato, and eggplant. We could also add wolfberry, tomatillo, brugmansia, calibrachoa, tobacco, and a score of others. None of the flowers are edible (many are toxic as are other parts of the plants), but quite a few of the plants produce edible (and delicious) fruits or roots or are otherwise economically important.
The answer? They are all members of the family Solanaceae, or the nightshade family. There's a family resemblance, though closer in some cases than others. It's good to know who's related to who, as often related plants are targeted by the same pests, and have other characteristics in common, such as not being good to snack on arbitrarily.
