It's called White Sage, and it comes in a "bunch", still on the stem, with hemp rope wrapped around it. The only place I've ever been able to find it around Central Florida is at the Super Flea on I-95 South, at the Eau Galle Exit.
OK, so now you're probably wondering how I know about white sage. Right after my mom passed away, a plant that I had brought home from her funeral went flying across my bedroom one morning and I wasn't sure if the cats knocked it over, or if she did it to let me know she was with me. When I got the White Sage, I was told to light it, and then wave it throughout the house, and then from corner to corner of my property. Given we are in "dry season", the sage burning might not be a good idea right now. I wish we could get a priest or minister to go out and bless the property, but that would probably require permission from the land owner.
