What are the pros? Color variation is great!
What are the cons? They can develop a blight.
I needed to add color to our property and I fancy yellow! We decided we would dedicate a large portion of a field for flowers. Preferably perennials. The first year, growth was slow, but evident. I did need to weed quite a bit to allow the new seedlings some air and sun. Once established, they did reseed themselves like the author above noted. Now, they have popped up everywhere. They also make an excellent gift for a hostess if you're in a hurry and couldn't purchase something. I will cut the flowers and put them into a mason jar for a quick country, summer-time look! Also, I dry mine by cutting them at various stages in their growth and then hand upside down in a dry, dark room. They are excellent as a dried flower!
