Sand is generally not a good growing medium for plants, a closed bag of sand even less so.  But Ailanthus altissima (also known as Tree-of-Heaven) will grow just about anywhere including a closed bag of sand. A closed bag of sand exposed to direct sunlight and summer heat.

While unwanted and unwelcome, there is something to be said for the tenacity of a tree that not only grows in Brooklyn but anywhere else.

And although Alianthus hasn’t invaded my blog, I have written about it here and here.
