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.

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.
