I am not a fan of the Morning Star line of incense. In general, I think it is low quality, smoky, and unpleasant. However, I did try this New Morning Star Grass fragrance, and found it to be much improved over the original line.
Grass is a pleasant green and leafy scent with a hint of citrus. Fresh is a good way to describe it. It's ok for inexpensive incense, but if you want a higher quality "fresh green" scent, I would recommend Fragrance Memories Spring Leaves, which is delightful.
I am tempted to try the other scent in the New Morning Star line...I believe it is a floral blend. If I do try it, I will leave my review.
