Year registered2004
Section classIII-1 (Medium)

Overview

Registered in 2004, 'Old Coot' is a medium-sized variegated hosta resulting from a cross between Hosta 'Sum and Substance' (pod parent) and Hosta yingeri (pollen parent). The cultivar is distinguished by its very heavy leaf substance, elliptic leaves with green, slightly rippled margins, and a highly glossy surface on both the upper and lower leaf faces.

In the Garden

'Old Coot' forms a mound-like clump reaching 38 inches (96.5 cm) in diameter and 14 inches (35.6 cm) in height, with a moderate growth rate. It performs best in partial to dappled shade, typical for variegated hostas, and is suitable for mid-border positions or as a specimen in shaded beds. Its substantial leaf texture pairs well with ferns, astilbes, and other shade-tolerant perennials.

Care Notes

Provide consistent moisture during the growing season, particularly in dry periods, and apply a balanced fertilizer in early spring as new growth emerges. The heavy leaf substance offers some resistance to slug damage, though standard slug management is still advisable in damp conditions.
