We have four of these plants that are loaded with blooms and buds. They are perennials, and grew from 2 plants that I planted a year ago. I thought I was buying daisies when I purchased them. But these are the tallest daisies I’ve ever seen!
After doing a little research online, I have concluded that these plants are swamp sunflowers. These plants are in a flower bed that is in front of our vegetable garden, which is definitely not a swampy area. In fact, we had a very dry summer, and I didn’t even water these plants when I was watering the roses.
