Southwest Colorado Wildflowers, Oreocarya

Oreocaryas are lovely plants with an abundance of tiny flowers, hairy leaves very evident in early spring, and persisting dried flower stalks. The Oreocarya genus is quite similar in appearance and characteristics to the Cryptantha genus, and, in fact, although the Colorado plant authority William Weber moved many members of the Cryptantha genus to the Oreocarya genus, most botanists have not followed his lead. Members of both genera are difficult to identify and often the distinguishing characteristic is the shape of the nutlet.

Weber separates the Oreocarya genus from the Cryptantha genus as follows:

Oreocarya: "Biennial or perennial from rosettes of basal leaves; flowers more than 5 mm in diameter, often distinctly long-tubular with prominent yellow eye."

Cryptantha: "Annual without rosettes of basal leaves; flowers minute, less than 5 mm diameter, short-tubed with inconspicuous eye."

"Oreos" is Greek for "mountain" and "caryum" is Greek for "nut".

See Cryptantha.

These bright Forget-Me-Nots are favorite spring Canyon Country wildflowers for many wildflower enthusiasts. They are abundant perennials commonly found along trails in Pinyon-Juniper forests and sandy/rocky openings. It is pleasant to watch the gray mass of last year’s dead leaves yield to new, very hairy, light-green to sage-green to blue-green leaves and then to numerous clusters of tiny bright flowers, also in a very hairy cluster (see next picture).

"Flava" is Greek for "yellow".

Oreocarya fulvocanescens shares the same habitat and many of the characteristics of Oreocarya flava above and Oreocarya flavoculata below. All three plants enjoy sunny, sandy/rocky soils and all bloom profusely for more than a month in the spring and early summer. Individual tubular flowers are quite tiny but are so massed that they are showy.

As you can see in the photo at left, it is common for the plants to show last year's dried flower stems and leaves. Plants grow to almost a foot tall, depending on the moisture and soil conditions. These three inch tall young plants probably grew to only six inches.

"Fulvo" "canescens", Latin, refers to the plants color: "tawny" "becoming gray".

In Colorado this Oreocarya is, according to William Weber, "probably the most common and variable species, from [the] Gunnison Basin westward, in sagebrush and pinon-juniper". It can be erect or reclining, is very hairy, and has flowers with a touch of yellow in the center and along the throat. It is a lovely plant. It is very similar to Oreocarya fulvocanescens shown immediately above and is distinguished primarily by the shape of its nutlets.

"Flavoculata" is Latin for "a little yellow".

Canyonlands National Park, Utah, April 14, 2004.

This dainty Cryptantha grows only on the Colorado Plateau in sandy and rocky areas. The flower is brilliantly white and eye-catching. Leaves are linear to spatulate and quite hairy.

"Tenuis" is Latin for "slim, slender".
