It is said to be an annual but I have had the same plant bloom for a couple of years after I trimmed it back when finished flowering.

Very easy to grow in sandy soil. Volunteers seedlings if not deadheaded. Flowers are 2" or so in diameter and are a very bright orange. Up to 5 flowers may be blooming at a time on a healthy mature plant!
