For this month?s discussion of material culture I want to contribute an example of a (presumed) Mormon giving Book-of-Mormon names to flowers. Daylilies are a common (at least the in US) landscaping flower that can be hybridized to create cultivars with a wide variety of colors and shapes. The American Hemerocallis Society?s Online Daylily Database has 75,000 entries, a few dozen of which come from RJ (Jack) Roberson. About thirty of Roberson?s cultivars have Mormon names. 
Roberson?s company, American Daylily & Perennials, sells King Lamoni, Lavender Nephite, Mormon, Mormon Halo, Mormon Spider, Raspberry Lehi, and Righteous Remnant.  In a 2009 email to me, Jo Roberson (Jack?s wife and business partner) wrote that:
He [Jack] chose this theme in general due to our appreciation of the Book of Mormon. More specifically, when naming the individual varieties, he gave a lot of thought to the plant and how its characteristics seemed to ?fit? with someone or something in the Book of Mormon. 
I don?t have any academic analysis to offer at this point other than that I think there are probably interesting things to be said about the giving of religious-themed names to not-obviously-religious objects.  Below are images of some of Roberson?s daylilies. 
The names are, left to right, top to bottom : Row 1: 1 Ammon, 2 Zarahemla, 3 Mormon Lemon Tart, 4 Lavender Nephite, 5 Mormon; Row 2: 1 Double Deseret, 2 Righteous Remnant, 3 King Lamoni, 4 Helaman, 5 Double Deseret; Row 3: 1 Helaman, 2 Ebony Lamanite, 3 Mormon Halo, 4 Raspberry Lehi, 5 Mormon Spider.
I believe it obligatory in a post like this to quote Ned Desaules :
Je ne crois pas que la cultivation des fleurs est une chose inutile. Par s?il faut que Sion fleurisse comme la rose, il faut bien qu?il y aient des fleurs.
I do not think that the cultivation of flowers is a useless thing, because if Zion is going to blossom as the rose, there must needs be flowers.
 An American Daylily and Perennials press release has more info on Roberson. If I?ve identified them correctly, the Mormon-named cultivars are: Abinadi, Ammon, Brother of Jared, Daughter of Ishmael, Double Deseret, Ebony Lamanite, Gentian Nephite, Helaman, King Benjamin, King Lamoni, Laman, Lamanite Rainbow, Lamanite Sunset, Lamanite Warrior, Land Bountiful, Lavender Nephite, Lehi, Lemuel, Liahona, Lilac Mormon, Mormon, Mormon Halo, Mormon Lemon Tart, Mormon Spider, Moroni, Mosiah, Nephi, Prophecy of Samuel, Raspberry Lehi, Sword of Laban, and Zarahemla. Other of Roberson?s efforts that might have a Mormon connection include: Ancient Alter, Blushing Sariah, Divine Intervention, Divine Providence, Israel?s Sunset, Marvelous Work, Righteous Remnant, Sariah, Sariah?s Rose, Tree of Life, and Zion?s Praises.
 They also sell 350+ other daylily varieties. Helaman is on the website but is ?currently unavailable.?
