Overview
Registered in 2011, *Hosta* 'Blue Tooth' is a medium-sized hybrid derived from a cross between *Hosta* 'June' (pod parent) and *Hosta* 'Azure Snow' (pollen parent). This cultivar is distinguished by its lance-shaped, blue-green leaves with powder blue margins and a pronounced glaucous bloom on both surfaces, which gives the foliage a muted, frosted appearance.
In the Garden
'Hosta' Blue Tooth forms a dense, mound-like clump reaching 18 inches (45.7 cm) in height and 36 inches (91.4 cm) in diameter, with a moderate growth rate. It performs best in partial to full shade, where its blue foliage color is most stable, and pairs well with other shade-tolerant perennials such as ferns, heucheras, and astilbes. Its medium size makes it suitable for border fronts, woodland gardens, or as a specimen in shaded beds.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced, slow-release fertilizer in early spring as new growth emerges. As with most hostas, slug and deer damage may occur; monitor foliage for signs of feeding and take protective measures if necessary.
