I have had a couple fresh rosemary sprigs in my refrigerator for about 1 1/2 weeks now. Are they still good?

I want to use them in my crock pot roast today. I Added my beef stock and other herbs, and want to lay the rosemary sprigs in the liquid as well, then place roast in pot to simmer all day. My question is, this is the first time buying fresh rosemary sprigs, bought them last wk for a recipe. Thought they sounded good for the roast. When I took them out of fridge today, they have a greenish/purple color on some leaves. Are they still good?? How do you store these sprigs for future use? Thanks.
