I've always liked Cosmos.
Here are some I planted this year.
"How would you like to own a universe? This will probably never happen but you can grow a plant which produces "showy flowers" in an "orderly arrangement of cosmic proportions". Cosmos is the flower you should grow. Spanish priest grew cosmos in their mission gardens in Mexico. The evenly placed petals led them to christen the flower "Cosmos," the Greek word for harmony or ordered universe.
