I read from some online links, that it grows and blooms from spring through fall, but on your site you mention spring and winter, that's why I didn't get it before. It would only be an annual (tender perennial) with each plant for me.
On the ATP database listing for this salvia, it reads:
Late spring or early summer
Late summer or early fall
Late fall or early winter
Is this incorrect? If so, then it needs to be corrected.
There are salvias that I'd love to grow but, since I'm zone 6a and don't have a greenhouse I can't.
