This may or may not be the day-neutral variety (most varieties do not start blooming until late autumn or early winter, by which time there is a risk of frost even in zones 8 and 9) I have not grown this (planted some, critters ate the seedlings to the ground) and can't say from experience whether it's day-neutral for me.
