      We enjoy the flavor of rosemary when used in cooking. Generally speaking, we have some growing in our garden. Sometimes if we have had too much rain it tends to die out. It would rather grow in dry conditions than too wet. That is a challenge in our humid climate of Houston. Thanks for all of this information regarding the health benefits of rosemary.

      Thanks for a really comprehensive guide to rosemary. I have tons of this herb growing in my herb garden, and I love it, but only ever seem to use it with roasted potatoes, or sometimes for decoration as a sweet scented cut flower. The tea sounds good, perhaps I will give it a try.

      Rosemary is one of the first things I learned to grow. Thankfully, it takes very little care and is easy to grow here, or I would have managed to kill it somehow. :) Thanks for the information.
