Hello, I have this mystery plant in my garden. I originally thought it was meant to be there so I let it grow, but now it's way taller than everything else in the garden, and I don't recognize it as anything I planted on purpose. I forgot to put a ruler to the photos, but to give an idea of the size, it's about 5 feet tall and the leaves are about 4-5 inches long. The flowers are roughly 3/4 to 1 inch across. If you have ideas of what this is, I'd very much appreciate it. Thanks!
