H. ‘Rosedale Dewy’
Hosta ‘Rosedale Dewy’ is a registered cultivar () .
| Year registered | 1999 |
|---|---|
| Section class | II-2 (Large) |
Overview
Originating from the cross of Hosta 'Galaxy' (seed parent) and Hosta 'Elegans' (pollen parent), 'Rosedale Dewy' was registered in 1999. This large cultivar is distinguished by its broad, cordate leaves of medium blue-green, which bear a pronounced glaucous bloom on both surfaces, lending a dewy, matte appearance.
In the Garden
'Rosedale Dewy' forms an upright, slow-growing clump reaching approximately 21 inches (53.3 cm) in height and 48 inches (121.9 cm) in diameter. Its substantial foliage, with leaves 8 inches (20.3 cm) long and wide, makes it suitable as a specimen or accent in part-shade to shade borders. The blue-green leaves pair well with golden or chartreuse-foliaged companions, such as Hosta 'Sum and Substance' or Carex elata 'Aurea'. Its large size precludes container culture for most situations.
Care Notes
Provide consistent moisture, especially during establishment, and apply a balanced fertilizer in early spring as growth emerges. As with most hostas, protect from deer and monitor for slug damage, particularly on the glaucous leaf surfaces.
