Overview
Registered in 1999 by an unknown originator, Hosta 'I’m So Blue' is a medium-sized cultivar distinguished by its intense blue-green foliage with a glaucous bloom on the upper surface. The leaves are cordate-based, 7 inches (17.8 cm) long and 6 inches (15.2 cm) wide, with slightly rippled margins and 10 to 12 vein pairs, while the undersides remain dull.
In the Garden
This cultivar forms an upright, moderate-growing clump reaching 30 inches (76.2 cm) in both height and diameter at maturity. It performs best in partial to full shade, typical for blue-leaved hostas, where the glaucous bloom is preserved. Companion plants include ferns, Heuchera, and shade-tolerant grasses; it is not suited for container culture due to its medium size.
Care Notes
Water regularly to maintain consistent soil moisture, particularly during dry spells. Apply a balanced, slow-release fertilizer in early spring as new growth emerges. Slugs and deer may damage foliage; monitor and apply controls as needed in typical hosta-growing zones.
