Some of these planters are made of bricks, others of wrought iron. i've seen morning glories and clematis, impatiens and ivy, all growing at the base of leafy trees. oak, maple, elm, birch, ash...you name it, it's probably growing in a planter somewhere in this city.
i used to think these planters were placed throughout these side streets for the beautification of the city and certainly this is a piece of the story since they are lovely and provide some nice flowers, after all. but i know better now. it is my observation that their primary function is to provide a place for the dogs of this city to evacuate their bladders...which they take full advantage of!
the city is getting a bonanza on fertilizer.
