Mini Bells, trailing petunia. Calibrachoa.
This is a worthy plant. Easy care, constant blooms. And deer resistant, I am told.
I am growing quite a variety of colors this year, and there were plenty other colors to pick from!
This quote seems especially appropriate:
Understanding is the basis of care. What you would take care of you must first understand. Whether it be a petunia or a nation. -Dallas Willard
