  • Scientific Name: Sisyrichium idahoense
  • Family: Iridaceae
  • English Names: Blue-eyed grass, Idaho blue-eyed grass
  • Other Names: Sisyrinchium angustifolium

Taxonomy

  • Kingdom: Plantae
  • (unranked): Angiosperms
  • (unranked): Monocots
  • Order: Asparagales
  • Family: Iridaceae
  • Subfamily: Iridoideae
  • Tribe: Sisyrinchieae
  • Genus: Sisyrinchium
  • Species: S. idahoense

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 blue to purplish-blue often with a yellow "eye", small (about 2 cm across) and in a terminal cluster of one to five flowers above a pair of sheathing, leaf-like bracts. Fruits egg-shaped capsules to 6 mm long, with black seeds [1]

Bloom Period

May to July

Distribution

Habitat

Ecological Setting

Moist to wet grassy meadows, vernal seepage areas, marshes, roadside ditches; at low to middle elevations [1]

Soil Texture

Fine to well-drained.

Soil Reaction / Salinity

Mildly acidic to alkaline (pH 5.5 to 7.5) [2]

Moisture Regime

Dry to fresh [3]

Shade Tolerance

Full sun to partial shade [3]

Successional Status

Considered a "weedy" species and a good colonizer [4]

Garry-oak Ecosystem Community Status

No information but probably a component of moister meadows in Garry oak ecosystems.

Uses

Site Rehabilitation

Possible reclamation species in moister pockets in selected sites [5]

Wildlife

Solitary bees of the family Megachilidae are mainly responsible for cross-pollination in natural populations. [2]

Landscaping

Mass-plant to create a showy display in a border or a rock garden [3]

First Nations

Infusion of root given to children for diarrhea; Eaten as cooked greens for “regular bowels”; decoction of roots and stalks taken before morning meal for constipation; compound with plant taken for “summer complaint”; infusion of plant taken for stomach troubles and stomach worms; mixed with other greens and eaten.

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 [2]

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 [6]

Seed Storage

Cold store at 5º C for up to three years [6]

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 [6]

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 [7]
