A few years ago Maryland decided to create pollinator meadows in some of its parks. They moved down the existing meadows, plowed them up and planted milkweed. Milkweed is a superb pollinator but it's tall. So I was not thrilled with the result - instead of being able to look out over the meadows I was walking next to a wall of plants. It was a bit like walking next to a cornfield - you are cut off from your surroundings.
However the milkweed didn't reseed very much the following year and in one park a beautiful pollinator meadow developed. There are yellow flowers that I don't recognize and lots of purple thistle. When my son started school in September this meadow was full of butterflies - dozens of them swooping and shining in the sun. It was wonderful to watch them!
