About the Art
Hidden Gems of the Sculpture Garden (Hidden Gems) was developed through conversations with horticulturalists, curators, and other artists in 2021. Louise “Ouizi” Jones thought of the mural during a campus tour in the spring, where she was moved by the rich landscaping of the Ada Hayden Herbarium and Reiman Gardens. Located in the Anderson Sculpture Garden outside of The Christian Petersen Art Museum, Jones modeled the colorful, yet delicate flowers and foliage after the ones planted in the area.
This educational and encyclopedic mural references real plants in the garden. Jones carefully chose each flower based on their color, meaning and shape. The peach-colored (Honeysweet) rose is named after Griffith J. Buck, a famed ISU professor of horticulture who bred these hardy roses while working at the university. Other flowers include: Brunerra (small blue pentamerous with white center); Japanese anemone (white with yellow center with 6-9 petals); Hellebore (purple flower with white and gold center pentamerous flower); Adiantum (“Maidenhair fern); Lily of the valley (small bell-shaped white flowers); and Beautyberry (groups of purple berries).
The flowers depicted in the mural bloom in different seasons. Hidden Gems allows you to experience them all year long.
About the Artist
Louise Jones (aka “Ouizi”) was born in 1988 and raised in Santa Monica, California. She is a Shanghainese-American. As a child, she would paint flowers with her mother, using watercolors. Jones is best known for her large-scale public floral mural installations. The murals often depict site-specific plants and animals, and the techniques she uses are uniquely informed by her background in drawing and printmaking. Her specialization in portraying botanical subjects in her art originates from her early interest in Georgia O’Keeffe. Jones currently lives and works in Detroit, has painted murals around the Chicago area, and continues to showcase her signature floral motif.
Example of Jones’ murals follow.

Georgia O’Keeffe (1887-1986) was an American modernist painter and draftswoman. Called the “Mother of American modernism”, O’Keeffe gained international recognition for her meticulous paintings of natural forms, particularly flowers and desert-inspired landscapes, which were often drawn from and related to places and environments in which she lived.

A gem is an object ofhigh quality or value. Like a treasure, a gem is prized, like a treasure, a gem is prized because of its beauty or worth.
A gemstone refers to any mineral that is highly prized for its beauty, durability, or rarity. Most gemstones begin as crystals of minerals (such as diamonds or sapphires), or as aggregates of crystals (such as malachite or jadeite). A limited number of non-crystalline materials of organic origin (such as pearl and amber) are also classified as gemstones and are usually referred to as organic gems. Gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity and notoriety are other characteristics that lend value to gemstones.
Raw gemstones can be enhanced to create more elegant gemstones by altering their shape, usually by polishing and/or cutting into cabochon or faceted shapes.
Cabochon is a gemstone that has been shaped and polished rather than faceted.
Cutting Cabochon is the best way to display colors and other optical effects in opaque or translucent stones is to cut them en cabochon– with a rounded upper surface and a flat underside. Cabochons are cut and polished on abrasive wheels, The stone is first ground to its outline shape and then the top is ground and polished into a dome using progressively finer abrasions. Stones have been cut into cabochon shapes for jewelry or decorating exquisite objects for centuries.

All gemstones above are cabochon gemstones mostly of pentagonal shape. The dark colored ones are Labradorite from Madagascar. The crystals are Clear Quartz from Brazil .
Faceting is the best way to maximize the beauty of a transparent raw gemstone by cutting it into flat reflective faces called facets. The ideal product of facet cutting is a gemstone that displays a pleasing balance of internal reflections of light known as brilliance, strong and colorful dispersion (aka “fire”), and brightly colored flashes of reflected light known as scintillation. Typically transparent to translucent stones are faceted, although opaque materials may occasionally be faceted as the luster of the gem will produce appealing reflections.
Early faceting of transparent stones into beads, scarabs, amulet seals, and bowls began around the 1300s and faceting of diamonds began around the end of the 1700s by European cutters.
Different outline shapes lend themselves to different cuts. Square or rectangular shapes suit the step cut. Round or oval shapes suit the brilliant cuts. Mixed cuts can be used on both.

Fun facts about sapphires, turquoise, and lapis lazuli:
The sapphire is a stone that is often enhanced into both cabochon and faceted gems.
Star Cabochon – When a sapphire stone that contains rutile needles oriented along the growth directions of the crystal is cut en cabochon, a star appears.
Brilliant – A brilliant cut is usually used for transparent sapphire to enhance its color.
Turquoise is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminum. It is rare and valuable in finer grades and has been prized as a gemstone for millennia due to its unique hue. The Southwest United States is a significant source of turquoise: Arizona; California; Colorado; New Mexico; and Nevada are especially rich.

Lapis lazuli or lapis for short, is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color. In ancient Egypt, lapis lazuli was a favorite stone for amulets and ornaments such as scarabs. Prized for thousands of years, Lapis was a favored stone in ancient Egypt, where it was believed to lead the soul into immortality and open the heart to love. Cleopatra’s iconic blue eye shadow was originally dust of Lapis Lazuli stones. Lapis Lazuli is believed to restore calmness and improve mental clarity in the wearers.

Griffith J. Buck is an American professor and a horticulturist. He taught horticulture at Iowa State University, and he created over 80 named cultivars of the rose, all of which are capable of withstanding temperatures of -20 °F and need no pesticides or fungicides to thrive. The Honeysweet (see below) is one of the roses.
