Description
A cute little North American native perennial, Sisyrinchium angustifolium ‘Suwannee’ is a super-floriferous Blue-eyed grass discovered in Madison County, Florida on the banks of the Suwannee River. Out of all the varieties we’ve ever grown none rival the flower power of Suwannee. LOADS of sky-blue flowers nearly cover the 8 to 10 inch tall clumps in late spring. What’s more…this one grows in almost any conditions, from sunny and dry to shady and wet sites.
Landscape & Garden Uses
Growing 8 to 10 inches tall and 12 inches wide, Suwanee Blue-eyed Grass is a perfect choice for use as an accent in small garden spaces or as a border edger along garden beds or paths and walkways. It looks great around rocks and boulders around the garden pond or as a grassy-textured and colorful accent in combination container gardens. A fine addition to ornamental grass gardens and blue theme gardens.
Suggested Spacing:Â 12 inches for mass plantings;Â 24 inches or more for space between plants
Growing Preferences
Suwannee Blue-eyed Grass is very easy to grow in most any moist to wet or even dry soil of average fertility and full sun to shade. Can be grown in pots that are situated at the margins of the garden pond. Essentially maintenance free. It slowly naturalizes into clumps by spreading roots but is not invasive at all. We rarely fertilize or prune it. In areas that experience colder winters the foliage may need to be groomed or cut back to the ground before new growth emerges in spring.Â
