Overview
Registered in 1999, *Hosta* 'Joanne Johnson' is a small-sized cultivar of unknown parentage. Its distinctive appearance derives from medium blue-green leaves with a slightly shiny upper surface and a glaucous bloom beneath, forming a compact, fast-growing mound.
In the Garden
'Joanne Johnson' reaches 12 inches (30.5 cm) in height and 24 inches (61.0 cm) in diameter at maturity, with scapes rising 14 to 18 inches (35.6 to 45.7 cm). It performs best in partial to full shade, typical of most hostas. Its small size and mound-like habit make it suitable for rock gardens, container plantings, or the front of shaded borders, where it pairs well with ferns, heucheras, and other small woodland perennials.
Care Notes
Provide consistent moisture during dry periods, particularly in the first growing season. Fertilize in early spring as new growth emerges. While not exceptionally prone to slug damage, standard preventive measures are advisable in damp conditions. Deer resistance is typical for blue-green hostas.
