Description
Showy, tufted perennial to 40 cm tall; stems usually flattened and wing-margined. Leaves mostly basal, long (to 20 cm.) and very narrow (< 2 mm broad).
Flowers consisting of 6 tepals, blue to purplish-blue with yellow centers. Flowers are small (about 2 cm across) and arranged in a terminal cluster of two to five flowers above a pair of sheathing, leaf-like bracts, emerging much lie irises.
1 prominent pistil and 3 stamens, ovary in inferior and pubescent.
Fruits egg-shaped capsules to 6 mm long, with black seeds [2][3]
Bloom Period
March to June
Distribution
Both S. i. var. occidentale (outer tepals 8-13 mm, inner spathe 12-20mm; spathe keel margins entire) and S. i. var. segetum (outer tepals 10-17 mm; spathe keel margins generally denticulate) have been reported in the South Salish Sea region. [4][3]
Habitat
Ecological Setting
Moist to wet grassy meadows, vernal seepage areas, marshes, roadside ditches; at low to middle elevations [2]
Soil Texture
Fine to well-drained.
Soil Reaction / Salinity
Mildly acidic to alkaline (pH 5.5 to 7.5) [5]
Shade Tolerance
Full sun to partial shade [6]
Successional Status
Considered a "weedy" species and a good early secession species after disturbance. [7]
Uses
Site Rehabilitation
Possible reclamation species in moister pockets in selected sites [8]
Wildlife
Solitary bees of the family Megachilidae are mainly responsible for cross-pollination in natural populations. [5]
Landscaping
Mass-plant to create a showy display in a border or a rock garden [6]
Propagation
Seed Propagation
Flowers are protandrous, thereby promoting out-crossing and at the same time reducing the chances for self pollination. S. idahoensis is an octoploid species and often exhibits a lag of up to 24 hours between anther maturation and stigma receptivity [5]
Fruit and Seed Collection and Extraction
Collect capsules by hand when ripe into collecting bags. Allow to dry further and then shake bags to extract seeds [9]
Seed Storage
Cold store at 5º C for up to three years [9]
Fruit/Seed Dormancy and Treatment
Seal seeds in a Ziploc-style bag or a Rubbermaid-style container in equal amounts of seed to perlite or vermiculite, and add just enough water to moisten the mixture. Cold stratify at 5º C for 8 to 12 weeks [9]
Outplanting Characteristics and Requirements
Out-plant in the fall to take advantage of natural moisture or plant in spring and provide supplementary watering. Successfully self-seeds in situ. Can be successfully divided in situ in the spring by simply teasing plants apart and replanting the resulting clumps [10]
