Overview
Registered in 1985 by L. Englerth, this medium-sized hosta originated as a hybrid of Hosta 'Tokudama'. It is visually distinctive for its heavy-textured, cupped blue-green leaves with blue-green margins and 15 pairs of veins, forming a compact, dense mound.
In the Garden
'Blue Horizon' reaches 12 inches (30.5 cm) in height and spreads to 32 inches (81.3 cm) in diameter, making it suitable for mid-border positions or as a groundcover in partial to full shade. Its blue foliage pairs well with golden or chartreuse-leaved companions such as Hosta 'June' or Carex elata 'Aurea'. The plant is not typically used in containers due to its medium size.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Slugs and deer may damage foliage; monitor and manage as needed in typical hosta-growing zones.
