Flowering May-Jul (to Aug at high elevations).
Fruits: Capsules tan to reddish-brown, ovoid, glabrous or sometimes sparsely glandular-puberulent, circumcissile or sometimes 5-valvate, 7-11 (15) mm.

Additional Notes
Loose umbels of magenta reflex-petaled flowers on stiff stems above small clump-forming rosettes of long oval leaves. One of the tallest species. Best in rich soil and part shade.

Family Information
Primulaceae:
Annual, biennial, or perennial forbs; scapose; from fibrous roots, short rhizome, or branched caudex, occasionally mat-forming or cespitose. Scapes ascending to erect, solitary or several per plant, unbranched. Leaves all basal, often rosulate, simple, unlobed, entire to toothed, subsessile to stalked, glabrous to pubescent, sometime glandular. Inflorescence a terminal, bracteate umbel, or flowers solitary. Flowers radially symmetric, 5-merous, bisexual, stalked; corolla campanulate or tubular to salviform, lobes sometimes sharply reflexed, usually whitish or pinkish to deep magenta, 4- to 5-lobed; calyces 4- to 5-lobed; stamens 5; filaments distinct or partially connate; ovary superior; style 1. Fruits 5-chambered dehiscent capsules, valvate to circumcissile. Genera 20, species ca. 600 (4 genera, 15 spp. in B.C.). Widespread in arctic, temperate, and subtropical regions of the northern hemisphere; disjunct in equatorial regions (e.g., e Africa, Indonesia) and in the southern hemisphere (e.g., s South America).
Non-scapose genera that were formerly included in Primulaceae ( Anagallis, Glaux, Lysimachia, Trientalis) have now been moved to Myrsinaceae (Källersjö et al. 2000, Trift et al. 2002, Cholewa and Kelso 2009). Many species in this family have a pronounced association with calcareous environments and are subsequently rather locally distributed within the province. Primulaceae contains a number of very showy species, and several genera have become important ornamentals in the horticultural trade (e.g., Primula, Dodecatheon).
Key to the Genera of Primulaceae
1a. Corolla lobes >2 times as long as the tube, sharply reflexed; stamens far exserted; filaments often at least partially connate (distinct in some species) .........................................................................Dodecatheon
1b. Corolla lobes less than twice as long as the tube, not reflexed; stamens included; filaments never connate…………………….........................2
2a. Calyces keeled (at least on the tube); plants densely cespitose (cushion-like) or mat-forming perennials with clusters of leaves at the bases of the scapes (rarely taprooted biennials), corollas rose-pink (fading to lavender, rarely to whitish).…...............................................Douglasia
2b. Calyces not keeled or only weakly keeled in fruit; plants taprooted annuals or perennials from fibrous roots or short rhizomes, or if mat-forming perennials (i.e., Androsace chamaejasme), then corollas white or pink-tinged with a yellow or pink throat..……………………….……………………………………………………………………………………...................................3
3a. Corollas constricted at the throat, magenta to lavender (rarely white), usually >7 mm across; plants never densely grey-hairy… ………………………………………………………...…………………………………………………..................................................Primula
3b. Corollas not constricted at the throat, white (sometimes fading pinkish in A. chamaejasme), usually <5 mm across (if >5 mm, then plants densely grey-hairy)…….……….......................................................……Androsace

Genus Information
Scapose, fibrous-rooted or short-rhizomatous perennial herbs, sometimes with numerous rice-like bulblets at the bases of the leaves. Scapes erect, solitary. Leaves all basal, rosulate, petiolate, simple, glabrous to glandular-hairy. Inflorescences terminal, bracteate umbellate or flowers solitary. Flowers long-stalked, the pedicels usually recurved (longer and more erect in fruit); corollas pink or white, tubular, usually white or yellow at the throat, with 4-5 long reflexed lobes; stamens well-exserted, usually dark purplish-black or reddish-purple, with short yellow filaments and anthers sometimes united at the base; ovary superior; calyces tubular, not keeled, glabrous or minutely glandular, 5-lobed, lobes spreading or reflexed and usually exceeding the tube. Capsules ovoid to cylindrical, exceeding the calyx, thin-walled, circumcissile and/or opening by five apical slits. 17 spp. (6 spp. in B.C.); North America, Mexico, e Asia.
The greatest diversity of species in this genus is found in western North America. Recent molecular-genetic research has convincingly demonstrated that Dodecatheon is derived from within Primula (specifically, from Primula subg. Auriculastrum) and therefore should be included within that genus to preserve its monophyly (Mast et al. 2004, Mast and Reveal 2007, Reveal 2009). It is retained as distinct here, however, due to its highly distinctive and consistent morphology, although nomenclatural combinations within Primula are provided for use if preferred. The evolution of Dodecatheon from within Primula subg. Auriculastrum has apparently been facilitated through an adaptation to buzz pollination in Dodecatheon (Mast et al. 2004). Species boundaries are not always sharply defined in this genus, and this is exacerbated by the tendency of populations to exhibit considerable vegetative plasticity in response to factors such as moisture levels, elevation, aspect, competing vegetation, and season. In addition, some species (i.e., D. pulchellum, D. conjugens) show significant geographic variation in the Pacific Northwest, which can blur the distinctions between the infraspecific taxa. Close investigation of the characteristics of the stigmas and filaments in Dodecatheon may be required for conclusive identification of some specimens, and these characters can be hard to observe in poorly-pressed specimens; the texture of the connective (the flattened portion of the anther between the pollen sacs) is of particular importance.
