Overview
Registered in 2010 by R. Kuenster through the American Hosta Society, *Hosta* 'September White' is a small-sized cultivar distinguished by its late-season bloom period and blue-green foliage with a glaucous bloom on both leaf surfaces. The ovate, lightly cupped leaves measure 6 inches long by 4.5 inches wide, with flat margins and 9 to 11 vein pairs, forming a compact, mound-like plant 10 inches high and 28 inches in diameter.
In the Garden
'September White' performs best in partial to full shade, typical for blue-green hostas, where its glaucous leaf coating remains most pronounced. Its small stature and moderate growth rate make it suitable for the front of shade borders, rock gardens, or container plantings, where it can be paired with fine-textured ferns or small woodland perennials. The green scapes, reaching 13 to 16 inches, bear flowers in September, extending the hosta bloom season into early autumn.
Care Notes
Provide consistent moisture during dry periods, applying a balanced, slow-release fertilizer in early spring as new growth emerges. While hostas are generally susceptible to slug damage, the glaucous leaf surface may offer slight resistance; monitor for deer browsing in areas where these animals are present.
