For the last couple of years I have put a bunch of these in a big pot. The grow like weeds, last forever, are gorgeous and finally you don't need to do a thing to them. Just enjoy their beauty. I bought these in May/June and right now they are still going strong. I was kind of sick and tired of the snug flowers and needed a change. And ps, Walmart had them for a couple of dollars. They look like big bucks, but are really just pennies.
