Yes, as the pp suggested, rosemary-infused olive oil is the first thing that comes to mind. If you use decorative bottles and pretty labels, they make nice gifts.
Marinade some chicken or lamb and freeze, so you have a few already prepped dinners ready.
Rosemary hair rinse is another idea. Just simmer 6 to 8 sprigs of rosemary in a quart of water. You can add a tiny bit of apple cider vinegar to it, if you like.
I suppose you could make bath salts with crushed dried rosemary instead of lavender.
Pot pourri is another thought, or a decorative wreath.
I'm a little envious of all that fresh rosemary!
