I discovered these beautiful, natural Yucca Fronds with amazing orange ends (where they once attached to the trunk) while walking my dogs.  I washed then in Dawn detergent, scrubbed them with a toothbrush and let them dry naturally.  Although they look as if I varnished/clear-coated them, I did not.  The shininess of the orange part is natural.  I am not sure of the Giant Yucca species, but I included a picture of the tree as the last image.  They are very strong and versatile for crafting and floral arrangements.  I included suggested use photos of them arranged in an antique crock, or used to make a wreath.  I think they are beautiful for fall or year-round.
There are 50 in a bunch.  Because I have not had them long, I do not know how the natural orange color holds up over time.  I would recommend that you avoid direct sunlight or exposure to the elements.  There is natural variation in length, size and intensity of color – though I hand-selected for the best specimens.  I tried to show examples of the variation in the photos, as well as both sides of the fronds.
