Frasera
albomarginata. Synonym:
Swertia albomarginata. (White-margined Frasera, White-margined Swertia). Gentianaceae (Gentian Family) Semi-desert. Rimrock,
openings. Spring. The basal leaves of Frasera albomarginata are a fairly common, and very attractive, Four Corners flora sight. Leaves in the basal rosettes are white-margined ("albo marginata") and often wavy. A stout stem branches and spreads to support numerous green/white flowers. The plant is typically eight to sixteen inches tall, but following the record breaking drought of the winter of 2005-2006, plants were no more than eight inches tall. Sereno Watson named this plant in 1871 from a specimen collected by Edward Palmer near St. George, Utah, in 1870. The genus was named by Thomas Walter for 18th century British nurseryman and plant collector, John Fraser. (More biographical information about Fraser.)

Frasera
albomarginata. Synonym: Swertia albomarginata. (White-margined Frasera, White-margined Swertia). Semi-desert. Rimrock,
openings. Spring. The basal leaves of Frasera
albomarginata dotted the ground by the thousands in the spring of 2020 following the massive seed production that resulted from the twice normal snowfall of 2018-2019. In the top photograph at left, six basal rosettes were just a few of the offsprings of one plant's bountiful production.
Individual rosettes are hauntingly attractive in their tentacle-like spread of green and white.
When you view an eight inch tall plant from the top, the myriad of leaves create another strange, yet attractive pattern. |

Frasera
albomarginata. Synonym:
Swertia albomarginata. (White-margined Frasera, White-margined Swertia). Gentianaceae (Gentian Family) Semi-desert. Rimrock,
openings. Spring. The dried plant persists for months. |
Frasera
paniculata. Synonym: Frasera utahensis, Swertia utahensis. (Utah Frasera, Utah Swertia). Gentianaceae (Gentian Family) Semi-desert. Sands, openings. Spring. This slender giant grows to nearly four feet and puts out an abundance of small, green/white flowers. (The flowers have evaded me, but someday I'll have photos of them on this website. Keep tuned.) Basal leaves are much longer and wider than those of Frasera albomarginata (above) and stem leaves are opposite whereas those of F. albomarginata are whorled. This plant is often misidentified in Utah Canyon Country wildflower books and National Parks as Frasera albomarginata. The white-margined basal leaves lead to this misidentification; the name "albomarginata" belongs to the plant shown at the top of this page, but the basal leaves of F. paniculata are also white-margined. "Paniculata" refers to the flower arrangement, a panicle, i.e., a branched raceme in which flowers mature from the bottom upwards. John Torrey named this plant in 1857 from a specimen collected by John Bigelow on the Whipple Railroad Survey in 1853 on "Sand-bluffs, Inscription Rock, Zuni County," New Mexico, in what is now El Moro National Monument. (Quotation from Intermountain Flora.) The genus was named by Thomas Walter for 18th century British nurseryman and plant collector, John Fraser. (More biographical information about Fraser.) |

Frasera
paniculata. Synonym: Frasera utahensis, Swertia utahensis. (Utah Frasera, Utah Swertia). Gentianaceae (Gentian Family) Semi-desert. Sands,
openings. Spring. This F. paniculata has its troubles: erosion has exposed the 3/4 inch thick root and critters have eaten chunks out of the leaves. It is still quite alive with flower buds. |

Frasera
paniculata. Synonym: Frasera utahensis, Swertia utahensis. (Utah Frasera, Utah Swertia). Gentianaceae (Gentian Family) Semi-desert. Sands,
openings. Spring. Last year's dry seed pods are supported by a slender stem and stand four feet above the dry basal leaves. (Stem and basal leaves are center right in the blurred background.) |
