Best Blue-Eyed Grass Sisyrinchium Angustifolium Plants and Seeds
For gardeners seeking blue-eyed grass (Sisyrinchium angustifolium), the most direct choices are live ‘Lucerne’ plants: the Perennial Farm Marketplace quart is best for a clearly described, established-size plant, while the Votaniki root is best for a compact perennial with grass-like foliage. The three seed listings offer a lower-commitment way to grow blue-eyed grass, but two are labeled Sisyrinchium bellum, a different species. Check the botanical name and growing details before choosing.
| Product | Best suited for | Key distinction |
|---|---|---|
| Perennial Farm Marketplace ‘Lucerne’ | Buyers wanting a live plant | Quart size; zones 5–8 listed |
| KVITER seeds | Seed growers open to another species | Listed as S. bellum |
| Votaniki ‘Lucerne’ | Compact perennial planting | Root listing; care guidance provided |
| Daylily Nursery three-pack | Planting several spots | Three plants; zones 5–9 listed |
| 200 Western blue-eyed grass seeds | Growing from a larger seed packet | Listed as S. bellum |
Perennial Farm Marketplace ‘Lucerne’
This quart-size live perennial is the clearest match for buyers specifically searching for Sisyrinchium angustifolium. The listing identifies the cultivar as ‘Lucerne’ and gives USDA hardiness zones 5–8. It describes blue, gold-centered, star-shaped flowers from May through July and iris-like foliage reaching about eight inches.
Best for: Gardeners who want a live plant for a rock garden, path edge, or cut-flower planting. It is selected for its explicit species and cultivar identification, bloom window, and planting guidance. The listing recommends full sun to part shade, well-drained soil, and spacing plants 12 inches apart.
Limitation: Its stated hardiness range is zones 5–8, so check local winter conditions if your garden falls outside that range.
KVITER Western Blue-Eyed Grass Seeds
KVITER offers 100 seeds identified as Sisyrinchium bellum, or western blue-eyed grass, rather than S. angustifolium. The listing gives a USDA range of zones 3–10 and a mature height of 4–16 inches. It describes spring-to-summer iris-like flowers and says established plants need minimal watering.
Best for: Seed-starting gardeners who want western blue-eyed grass for a border, rock garden, lawn, or container and are comfortable selecting a species other than the one in the search term. Its broad stated hardiness range and flexible light conditions are useful comparison points.
Limitation: Avoid this listing if you specifically need Sisyrinchium angustifolium; the product name identifies S. bellum.
Votaniki ‘Lucerne’ Root Plant
This one-pack listing identifies ‘Lucerne’ as Sisyrinchium angustifolium and describes a root for planting. It highlights slender, upright, grass-like foliage that adds texture even when the plant is not flowering. The product information recommends well-draining soil, moderate watering, and occasional deadheading.
Best for: Buyers who want a named live perennial for a border, container, rock garden, or path edge. Choose this if foliage form and several garden-use options matter as much as the flowers. The listing also describes the plant as drought-tolerant once established.
Limitation: The supplied product details do not specify a hardiness-zone range, mature dimensions, or bloom months, so verify those needs before purchasing.
Daylily Nursery Three-Plant Pack
This listing provides three plants of Sisyrinchium angustifolium ‘Lucerne’. The stated growing range is zones 5–9, with a mature height of 8–10 inches and spread of about 12 inches. It lists late spring to early summer as the bloom period and describes the flower color as purple.
Best for: Gardeners who want multiple plants for a small grouping or repeated placement. It is selected for its three-count format and listed size and spacing information, which help with planning a bed or border.
Limitation: The listing describes the blooms as purple, while other product descriptions call them blue. Flower color can be described differently by sellers, so consider that variation if color matching is important.
Western Blue-Eyed Grass Seed Packet
This listing offers 200 seeds identified as western or Californian blue-eyed grass, Sisyrinchium bellum. It lists a height of 6–8 inches, spacing of 12–18 inches, and hardiness zones 5–9. The stated bloom period is January through June.
Best for: Gardeners who want to sow a larger quantity of western blue-eyed grass and have room to grow from seed. Its listed height and spacing are helpful when planning a naturalized patch or distributed planting.
Limitation: This is a seed product for S. bellum, not the S. angustifolium named in the search. The listing does not provide detailed germination instructions.
Buying Guide: Choosing Blue-Eyed Grass
Do you want a live plant or seeds?
A live plant or root is the more direct option if you want to add a perennial to the garden without starting from seed. The Perennial Farm Marketplace and Votaniki listings identify ‘Lucerne’ as S. angustifolium; the Daylily Nursery listing offers three of the same named variety. Seeds suit gardeners who prefer to grow plants from the start, but check the species name carefully.
Does the species name match your garden plan?
Sisyrinchium angustifolium and Sisyrinchium bellum are not interchangeable product labels. The KVITER and 200-seed listings specify S. bellum. If you are seeking S. angustifolium, prioritize listings that name that species and confirm the label before buying.
How should you compare size and site requirements?
Compare listed hardiness zones with your location, then consider mature height, spread, light, soil, and spacing. The Perennial Farm Marketplace listing recommends full sun to part shade and well-drained soil. The three-plant listing gives an approximate 12-inch spread, while the seed listing for S. bellum recommends 12–18-inch spacing. Use the seller’s stated details as a starting point, not as a substitute for local growing guidance.
What should you verify before ordering?
Confirm whether the product is a seed packet, root, single live plant, or multi-plant pack. Check botanical name, quantity, zone range, and the seller’s current delivery and planting instructions. Flower color descriptions vary across these listings, so avoid relying on color wording alone when selecting a particular species or cultivar.
