Sisyrinchium angustifolium 'Lucerne' has fine, grass-like foliage and bright blue to purple, star-shaped flowers with gold centers. Also called Blue-Eyed Grass, it blooms for 8-10 weeks in late spring and early summer. It blooms are larger and more abundant than the species. It is visited by various native bees and pollinating flies. Songbirds eat its seeds.

Sisyrinchium angustifolium is native to much of North America, including eastern Canada, south to Florida, west to Texas and Minnesota. It is typically found growing in floodplains, along woodland edges and clearings, on riverbanks, on roadsides and in moist meadows.

Sisyrinchium angustifolium prefers sun to part shade and moist, well-drained soil. Plants may self sow where happy. Avoid heavy mulch which may encourage crown rot. A careful look at the plant will reveal its kinship to Irises.

We ship via UPS or USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.

All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.

We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
