Sisyrinchium sp. or Blue-eyed Grass typically reaches 2-5 feet tall and prefers to be planted in a sunny location with regular waterings. These plants feature white, off-white, blue, lavender, and purple flowers. Some varieties will even produce yellow or orange flowers.
Sisyrinchium sp.can be grown in USDA Zones 4-9. In colder regions, it is best to plant Sisyrinchium sp.in pots and bring it indoors during the coldest parts of winter.
When caring for this plant, it is important to give the plants plenty of sun and water regularly. If grown in a pot, they should be planted in a well-draining potting soil and should be given more frequent watering than if grown in the ground as the soil will tend to be more moist. They should be fertilized once every few months with a balanced fertilizer,.
