Thanks, Tom. There were a lot of these flowers, also, and I had to do research on those, too. If the one above is a Mexican Sunflower, do you know what this one is?

There are different kinds of Mexican sunflowers you may well have two different types. The plants get quite tall perhaps five or 6 feet and the flowers are striking if it is a Mexican sunflower.

Yes! They are both VERY tall! Both, I would say are 6 feet for sure. That's wonderful! Thank you so much for your help! (The butterflies love both of them, and I want to make sure that I save the seeds and plant more next year!) Thank you!

You may want to stake them, Michelle. They tend to get blown over in storms and if that happens sometimes the main stem will break and you will lose much of the plant, and, of course, the flowers. Your pictures are very good. They look healthy. I'm sure the butterflies are enjoying them.

I did have one huge plant blow over. It didn't break, so I just tied it up to a stake. This is the first year that I have planted flowers and plants for the butterflies. I absolutely LOVE watching the butterflies enjoy them. Thank you so much for your help, too, Tom!
