It's a fight to the death
Who ever said that flower gardening was a gentle sport? Who can pretend that all is light and best wishes out in the flower garden?
This is a blood sport.
To the victor goeth the spoils and in this case, survival.
There's only going to be one winner in this epic struggle and it's anybody's guess. The bindweed (Convolvus arvensis) has a chokehold on the daylily (Hemerocallis fulva) and it is anybody's guess who's going to slap the mat first.
I saw these two going at it the other day at the marina where I keep my boat and couldn't help but be amazed at how Mother Nature really does let the fit survive and the weak perish. Both of these guys were growing in gravel and rock and full hot sun but ready to fight for their turf. The bindweed had completely pulled the flower stalk sideways (this is not trick photography) and was pulling it down with its weight.
But the winner will be determined next year when we see who survives the winter.
