I've got a small meadow which for years produced Asclepius tuberosa and incarnata. They have not reappeared this year, but A. syrica is showing up from who knows where.

Also, the NY Ironweed seems to have disappeared.

At the same time, several varities of goldenrod are really taking over everywhere and I've had to pull at great deal of it out.

Is anyone else noticing similar happenings?
