Sisyrinchium angustifolium 'Lucerne' is a cultivar of the native Blue-Eyed Grass species, known for its striking blue flowers and compact, tufted growth habit. This cultivar, commonly called Lucerne Blue-Eyed Grass, stands out with its vibrant, blue petals that surround a bright yellow center. The flowers, which bloom in late spring and early summer, are borne atop slender, grass-like stems that rise about 6-12 inches above the dense, linear foliage.

Lucerne Blue-Eyed Grass is an excellent choice for adding pops of color and texture to garden beds, borders, and rock gardens. Its small stature and clumping growth pattern make it well-suited for edging paths, spilling over retaining walls, or incorporating into mixed perennial plantings. This cultivar shares the same low-maintenance requirements as the species, thriving in full sun to partial shade and well-drained, average soils. It requires little to no supplemental watering once established and does not need regular division or deadheading to maintain its attractive appearance.

Limited Availability

We try very hard to source exactly what you’d like, but sometimes growers run out of plants! While this variety is a great deal at the price shown, we know that it has limited availability. If you want the plant even if it might be more expensive, or in a different size or quantity -- after you place your order, just send us a quick note at help@northshoreplantclub.com. Then, we’ll try to get you some version of this from one of our growers. And if we can’t get it from anywhere, of course, we’ll send a refund!


Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

About Ordering From The Plant Club

To secure the best prices for club members and make sure we know the current plants available from each nursery, we take orders only a couple of times a month.

The next order is coming up soon. Here's a link to our ordering calendar. Shoot us an email at help@northshoreplantclub.com, and we'll be happy to talk about plants or let you know when it's time to buy them!


No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
