The advantages Rue adds make it worth a try. It is sometimes used as a host plant by two species of butterfly, it's easy to care for and it blooms fairly often...even in the winter for me...attracting those early butterflies. Right now I've got Red Admirals, sulfurs and at least one Gulf Fritillary around here during this warm spell. I had some really nice orange zinnias last year, although I don't remember the name. I also use drought tolerant natives as much as I can. Last couple of years I've become fond of Goldeneye, which grows out on the property away from access to watering.
