Seeding: Blue-eyed grass self-seeds fairly easily, but it can be more temperamental in pots. Try planting in pots outside, and keep moist during the growing season. Seeds may not germinate until second year. If they don’t germinate the first year, bury the pots up to the rim for the winter, and check again the following year. You can also try a combination of warm and cold stratification periods indoors. See the Plant Info page for more detailed information on growing from seed.

Landscape uses: This delicate looking plant is good for a border, or as a grouping with other similar-sized plants. Suggested spacing for planting is 8 cm for a denser planting, and up to 15 cm for a more open look.

Interesting features: Despite the name, blue-eyed grass is a member of the Iris family. The flowers open early in the day, and close by midday.

Natural habitat: Moist open areas. Often grows in colonies among grasses.

Ecology: Nectar source for bees, butterflies and other small pollinating insects. Birds may eat the seeds.
