Across the street from my house is a river, and a sort of elongated park runs along the river on both sides. Lately the lawn was absolutely white with masses of white clover, along with some purple clover and some "white" clover that had turned pink. It was very pretty and it smelled good.
But bit by bit, it all got mowed. They missed a couple patches of white clover, and even one stalk of purple clover, but not much. Stupid lawnmowers. The grass wasn't even that tall.
However, I will say that this year there are several clumps of yellow iris growing on the river bank. I don't recall seeing them before -- perhaps they are newly planted. Or perhaps this rainy spring was good for them.
