Yes, deer love roses, and fresh tender raspberries too.
I snap off the garlic scapes as soon as I see them, they are tender then, and better to cook with if you want. Sooner is better than later, and later is better than not at all. With scapes removed, more resources are diverted to bulb growth.
Look up "Smilax". Many different species, but fits your description.

I finally got pumpkins, squash and melons in today. Fertilized and tillled before last rain. Today was spraying herbicide, waiting for it to dry, then mudding them in and watering with fertilizer and a systemic insecticide. Then spraying them with a different insecticide and a fungicide. Still have gourds and a couple specialty squash to go, but they will have to wait until next week, expecting another 2-4" of rain tomorrow.
