It grows a small round tuberous root and it one of the earliest wildflowers of spring in its range. It is found in dry meadows in forests of ponderosa and Chihuahuan pines, and moist ledges of mountain slopes of the Beaver Dam Mountains of Utah, Colorado Front Range, and Sierra Madre Occidental (including the Chiricahua Mountains), south and east to the Sierra Maderas del Carmen of Coahuila.{{cite journal |last1=Miller |first1=John M. |last2=Chambers |first2=Kenton L. |title=Systematics of Claytonia (Portulacaceae) |journal=Systematic Botany Monographs |date=2006 |volume=78 |pages=1–236 |url=https://www.jstor.org/stable/25027952 |access-date=4 August 2024 |isbn=0-912861-78-9 |issn=0737-8211}}{{Cite web |url=http://wnmu.edu/academic/nspages/gilaflora/claytonia_lanceolata.html |title=Vascular Plants of the Gila Wilderness-- Claytonia rosea |website=wnmu.edu |access-date=10 August 2017 |url-status=dead |archive-url=https://web.archive.org/web/20240330222626/https://www.wnmu.edu/academic/nspages/gilaflora/claytonia_lanceolata.html |archive-date=30 March 2024 }}
Description
Claytonia rosea grow a small round tuber 20–100 mm in size with a corky or woody skin that is 5–10 mm thick to protect it. The stems can be {{Convert|2-15|cm|abbr=on|sigfig=1}} long, but are absent when the plant is not large enough to flower. When the plant is young it will have leaves that rise directly from the soil on individual leaf stems (basal leaves). These basal leaves are blade linear to narrowly spatulate, {{Convert|1-7|cm|abbr=on|sigfig=2}} long and {{Convert|0.4-2|cm|abbr=on|sigfig=1}} wide. This difference helps to distinguish them from Claytonia lanceolata with its wider leaves. In addition, close examination of the leaves will show that C. rosea has leaves that are single ribbed or indistinctly triple ribbed in contrast to the distinctly triple ribbed leaves of C. lanceolata.{{cite journal |last1=Shelly |first1=J.

The flower or bud will usually have multiple bracts, though rarely there will be just one bract. The bract that is closest to the flower will be leaf like, while the more distant ones are reduced to thin scales. Each flowering stem (inflorescence) will have about five to ten flowers. The sepals that enclose the bud open to be 3–5 mm in length. Each flower is 8–14 mm across with five pastel colored petals in a shade of pink, rose, or magenta. The petals are 8–10 mm long and the flower will have six ovules. The flowers also have five stamens that have pink tips. In the central part of its range in Colorado it blooms from March to May, rarely as late June. In Arizona they bloom as early as February in the lower parts of its habitat and as late at May at higher elevations. The flowers only open during warm and sunny weather, closing at night and during cloudy or wet weather.{{cite web |last1=Dingwell |first1=Sue |title=Spring Comes to Joder Ranch |url=https://conps.org/spring-comes-to-joder-ranch/ |website=Colorado Native Plant Society |access-date=25 May 2023 |date=14 April 2022}} In a few warm microclimates in on rocky outcrops or south facing bare ground in the foothills near Denver they will sometimes bloom as early as the first of January and may do so in similar situations in other parts of their range.{{cite book |last1=Jones |first1=Stephen R. |last2=Cushman |first2=Ruth Carol |title=Colorado Nature Almanac : A month-by-month guide to wildlife & wild places |date=1998 |publisher=Pruett Publishing Company |location=Boulder, Colorado |isbn=978-0-87108-883-3 |page=32 |url=https://archive.org/details/coloradonatureal0000jone/page/32 |access-date=24 March 2024 |language=en}}
The seeds of Claytonia rosea are very small, 2–3 mm, about the same size as a poppy seed. They are smooth, shiny, black in color, and shaped like a lens.{{cite web |title=Claytonia rosea - western springbeauty |url=https://cals.arizona.edu/yavapaiplants/SpeciesDetailForb.php?genus=Claytonia&species=rosea |website=Yavapai County Native & Naturalized Plants |publisher=Arizona Cooperative Extension |access-date=13 April 2023 |location=Prescott, AZ |date=13 December 2022}} The seeds have a 1–2 mm elaiosome, a fleshy structure that is usually associated with ant dispersal of seeds. The seed capsules have three valves.
Taxonomy
Claytonia rosea was described by Per Axel Rydberg in 1904. In 1966 Ray J. Davis published an article classifying it as Claytonia lanceolata var. rosea in the journal Brittonia.{{Cite POWO | last1 = POWO | author-link1 = Plants of the World Online | year = 2023 | id = 59967-2 | title = Claytonia lanceolata var. rosea (Rydb.)

Halleck and Delbert Wiens published an article setting forth an argument in favor of its status as a species.

Habitat and distribution
Claytonia rosea is the earliest flower of spring in the foothills and montane forests. It It grows in small meadows, open hillsides, canyons, ravines, and mesas of montane ponderosa pine, Chihuahuan pine, and oak belts. In New Mexico they are reported to be found more often on north facing slopes or in shaded canyons. They are recorded growing from {{Convert|800-2400|m|sp=us}} in elevation.
The exact range of Claytonia rosea is uncertain with different authorities recording different areas. POWO records it in the four corner states of Colorado, Utah, New Mexico, and Arizona and the Mexican state of Coahuila. PLANTS additionally records it as growing in Wyoming and Montana.
NatureServe has assessed the global status of Claytonia rosea as G4 - apparently secure, an uncommon but not rare species.{{cite web |last1=NatureServe |title=Claytonia rosea Western Springbeauty |url=https://explorer.natureserve.org/Taxon/ELEMENT_GLOBAL.2.160808/Claytonia_rosea |website=NatureServe Explorer |publisher=NatureServe |access-date=7 April 2023 |location=Arlington, Virginia |date=2023}}
Ecology
The first scientific observation of the Lasioglossum bee species L. perpunctatum was on flowers of Claytonia rosea near Boulder, Colorado by T.D.A. Cockerell and Marion Durbin Ellis.{{cite web |title=Lasioglossum perpunctatum (Ellis, 1913) |url=https://www.discoverlife.org/mp/20q?search=Lasioglossum+perpunctatum&flags=subgenus: |website=Discover Life |access-date=13 April 2023}}{{cite journal |last1=Ellis |first1=Marion Durbin |title=Seven New North American Bees of the Genus Halictus (Hym.) |journal=Entomological News, and Proceedings of the Entomological Section of the Academy of Natural Sciences of Philadelphia |date=1913 |volume=24 |issue=5 |pages=201–211 |url=https://www.biodiversitylibrary.org/item/84917#page/24 |access-date=13 April 2023 |publisher=Entomological Rooms of the Academy of Natural Sciences |location=Philadelphia, PA}}
Cultivation
Rocky mountain spring beauty is occasionally grown in rock gardens or by those interested in wildflower gardening. Replanted corms will persist for a time even in less than ideal conditions, but will decline without reproducing if planted in areas subjected to either extreme drying during the summer or being flooded during rainstorms.{{cite book |last1=Barr |first1=Claude A. |title=Jewels of the plains : wild flowers of the Great Plains grasslands and hills |date=1983 |publisher=University of Minnesota Press |location=Minneapolis |isbn=0-8166-1127-0 |page=60}} Gardeners increase the numbers of this plant by seed rather than by division. Rich, well drained soil is their preferred condition in a garden setting.{{cite book |last1=Smyser |first1=Carol A. |editor1-last=Hylton |editor1-first=William H. |editor2-last=Posner |editor2-first=Marcy |title=Nature's Design : A Practical Guide to Natural Landscaping |date=1982 |publisher=Rodale Press |location=Emmaus, Pennsylvania |isbn=978-0-87857-343-1 |page=194 |url=https://archive.org/details/naturesdesignpra00smys/page/194 |access-date=31 January 2024 |language=en}} Plants are tolerant of being moved when blooming. Plants will freely reseed to produce additional individuals.{{cite book |last1=Mossman |first1=Tam |title=Gardens that Care for Themselves, How to Grow Neater, Healthier Plants, and Cut Your Outdoor Chores in Half |date=1978 |publisher=Doubleday & Company, Inc. |location=Garden City, New York |isbn=978-0-385-11171-3 |page=234 |url=https://archive.org/details/gardensthatcaref00moss/page/234 |access-date=24 March 2024}}
The roots, though small and not usually abundant, are edible. The wild foods author Harold D. Harrington found them to be crisp and starchy without much flavor when raw, but rather like earthy potatoes when boiled.{{cite book |last1=Harrington |first1=Harold David |title=Edible Native Plants of the Rocky Mountains |date=1967 |publisher=University of New Mexico Press |location=Albuquerque, New Mexico |isbn=978-0-8263-0343-1 |pages=168–170 |edition=9th Printing |url=https://archive.org/details/ediblenativeplan0000harr/page/168 |access-date=24 March 2024}}
