I saw these plants on a recent walk in the neighborhood and was able to catch a "before" and "after" of these Yucca gloriosa 'Variegata' (not sure I've got the plant ID exactly right, but that's close) as they were being groomed to remove old, unsightly, winter-damaged foliage. Sometimes the difference between having a Yucca plant that looks great, one you're happy to be growing, and one that looks unkempt and unattractive is just a few minutes of elbow grease.
