Wishbone Wannabe

This purple flower earns its name due to the two stamens connected at the anthers which resemble a chicken's wishbone.  Kind of looks like that, doesn't it?   But, it's a bully.  I planted it in an antique bathtub out by the edge of the woods.  Last spring when I went to buy some annuals for my tub I asked a knowledgeable-looking woman at the local plant store for advice, being the novice, inexperienced, frustrated gardener that I am.  I wasn't at Home Depot where everybody looks tired and tries to avoid eye contact.  This was the real thing.  A store and a woman where plants are their purpose.  She told me, "Well, get something that will flow over the side.  And something to fill in."  So I bought a few of these wishbone plants (the spillovers) along with a few pink impatiens (the fill-ins).   Sadly but maybe to no surprise, all I see now, as summer is in its last hot month, is a mass of these purple wishbone flowers, bullying the pink impatiens into submission behind the weird and otherworldly tall plants I stuck in the middle.  Always learning. Failing and learning.  After seriously trying to tend my gardens this year, I am filled with enormous appreciation for anybody who gardens well. I am fully aware now how much time it takes to research, water, fertilize, and pray to make a garden come alive.  And there's some luck in there, hiding under a bush.  The knowledgable woman at the garden store also said, "Take a picture of what grows so you'll know for next year."   I am filing away a picture of this domineering ground-covering plant with purple blooms the size of a quarter that has commandeered my tub.  Little bugger.  I am hoping in the future I can plant with more purpose and less surprise.  But maybe not.  Everything changes.  This summer is climate change hot so that has created a completely different growing environment than the rainy one last year.  Like life.  I suppose I should just take it as it comes.  Although I am thinking about snapping that chicken wishbone wannabe encircling the center of that purple bloom and making a wish to the gardening fairies.  Maybe that'd help?
