The common names of this plant refer to the interesting, and somewhat ferocious, seed pods - hopefully I'll have an example later this year. So far, I'm just happy to see the speckled, petunia-like flowers. Leaves are velvety. By early July, the plant is a monster, competing even with the squash plants surrounding it. Fruits appear later in summer. In our climate, ripening of the fruits into the trademark seedpods doesn't happen until about the time the frost kills the plants - but we did get viable seed, so I'll give them another go next year.
