I was surprised when I moved into a German apartment that my landlord apologized about their being moss between the tiles on our patio. My honest response was, "oh no, moss looks better than an empty crack." I was really surprised when I for the first time saw people outside literally using blow-torches to kill moss in their driveway cracks. The dislike of clover is a really strange one for me, too. When I was growing up I loved the clover patches in the yard; they're like green clouds floating across the lawn, and the honeysuckle brings happy honey bees. Dandylions are pretty, too, admittedly more so in the yellow phase than the gray phase. But then they make nice toys! Generally speaking I find the natural aesthetic more beautiful and more serene than the golf course look.
