|---|---|
| Section class | IV-2 (Small) |
Overview
A sport of *Hosta* 'Blue Mouse Ears' registered in 2011, 'Jumbo Mouse Ears' is a small-sized cultivar distinguished by its nearly round, deeply wavy blue-green leaves with a dull upper surface and glaucous bloom beneath. The leaf margins exhibit an embroidered edge, a subtle but consistent feature that sets it apart from its parent.
In the Garden
'Jumbo Mouse Ears' forms a dense, mound-like clump reaching approximately 15.8 inches (40.1 cm) in diameter and 5.9 inches (15.0 cm) in height, with a moderate growth rate. It performs best in partial to full shade, typical for blue-leaved hostas, where the glaucous bloom remains most pronounced. Its compact size makes it suitable for rock gardens, troughs, or the front of shaded borders, paired with small ferns or woodland perennials such as *Heuchera* or *Tiarella*.
Care Notes
Provide consistent moisture during the growing season, particularly in warmer climates, and apply a balanced slow-release fertilizer in early spring as new growth emerges. While slugs and deer may browse the foliage, the thick, wavy leaves offer moderate resistance compared to thinner-leaved cultivars.
