I found this Ailanthus seedling in a dirt pile I had delivered last year. The pile had been neglected for a while and was full of weeds. I’m not sure where the dirt originated from, but it’s probable that it came from a location where Ailanthus is present and a seed landed in the dirt. The seed then germinated and grew into this sapling. I have not seen Ailanthus anywhere within about a 40 mile radius of my location so I was shocked to find it.
