Individual stalks can be use with the same or different size stalks to create several styles of arrangements. All straight stalks are measured from the roots to the top of the stem. The length of the leaf varies and is not part of the measurements. If you prefer short or longer leaves, let us know the length of the leaf in the comment box when you check out. We will send the closest match to your request. If no special request was made, we will send the stalks with the most roots and leaves.
