In any other trailer park, I would've been surprised to find lettuce spontaneously growing in the yard. But in my backyard, otherwise strange things are the norm. (For example, no one else in my neighborhood [or probably the world] has a sentient compost pile.) Lopstick is ground zero of a former Superfund site, and only the strongest flora and fauna survive in this hamlet's unique æther. The lettuce I planted in my lined bed garden last year bolted, and the seeds scattered.
This former lettuce seed stepped outside the safety of the garden.
And this hardy lettuce is a traveling mutant.
Edible? So far, yes; I've been sampling the leaves.
But I think I've acclimated...
