Strict Blue-Eyed Grass (Sisyrinchium montanum) - Description
Sisyrinchium montanum, or strict blue-eyed grass, is a grass-like species of plants from the genus Sisyrinchium native to northern North America from Newfoundland west to easternmost Alaska, and south to Pennsylvania in the east, and to New Mexico in the Rocky Mountains. It is very similar to S. angustifolium, with which it is sometimes combined.
Strict Blue-Eyed Grass (Sisyrinchium montanum) - Blooming
Blooms star, cup, or trumpet shaped flowers in a range of colors such as white, yellow, blue, and mauve.
Strict Blue-Eyed Grass (Sisyrinchium montanum) - Growth
Does best with full sun exposure. Where Sisyrinchium is not growing hardy, raise plants in a cool greenhouse or alpine house. Cool greenhouses have a minimum temperature of 35ºF (2ºC). During the day, set temperatures between 41-50ºF (5-10ºC), and at night, keep the temperature at 36ºF (2ºC). Where hardy, smaller species work nicely in a rock garden or gravel planting. Taller ones are suitable for a herbaceous border.
Strict Blue-Eyed Grass (Sisyrinchium montanum) - Planting
Propagate from the seed. Sow seeds in containers in a cold frame in fall or early spring. Cold frames are protective structures, located outside for propagating and growing plants. Some species self seed freely, like S. californicum, S. graminoides, and S. idahoense. Conduct division in spring. Division entails propagating a plant by splitting it into 2 or more parts. Each part has its own root system and more than one shoot or dormant bud.
