Our armur maple was planted by Earl May maybe 10 hrs ago, but not until last summer did I see black stains on our patio where the samaras had blown there in a rain storm. As the seeds dried, the black stems bled black and stained the concrete, looking as though fireworks “snakes” had been lit in those spots. I tried to brush scrub the concrete with numerous cleaning products, but nothing but months of summer sunlight would fade the mess. It was a very poor selection for numerous other reasons and several times my husband threatened to have it taken out. This was not the shorter, spreading tree we had admired on the Earl May property—that store associate misidentified that by a long shot. Bad tree!
