The Fainting Bush is one that I almost wish would stay that way - like a Salvador Dali painting on the ground. But, in a way I'm glad that it rights itself. This normally occurs right after a scape has finished with all its blooms. The fan just pancakes onto the ground, looks pathetic for a week or three, and then just as quickly pops right back up again with new foliage to boot. I can almost hear a whisper right after the scape finishes up blossoming: "My gosh that was exhausting!" ... and then "Timber!" as the fans collapse.
I know I am not alone in having fans that sometimes do this ... fess up, you guys, when does it happen in your garden? Any thoughts about why?
