|---|---|
| Section class | II-2 (Large) |
Overview
Registered in 2003, Hosta 'Tidewater' is a large hybrid derived from H. kikutii var. leuconata as the pod parent and H. 'Elegans' as the pollen parent. The cultivar is distinguished by its intensely blue-green foliage, which carries a pronounced glaucous bloom on both leaf surfaces, and its substantial mound-like habit.
In the Garden
'Hosta' Tidewater' reaches a mature diameter of 40 inches (101.6 cm) and a height of 18 inches (45.7 cm), with scapes rising 20 to 36 inches (50.8 to 91.4 cm). It performs best in partial to full shade, as is typical for blue-leaved hostas, where the glaucous bloom responsible for its blue coloration is best preserved. The large, ovate leaves with flat margins and rounded bases pair well with ferns, Heuchera, and other shade-tolerant perennials; its moderate growth rate makes it suitable for mid-border positions in woodland gardens.
Care Notes
Provide consistent moisture during the growing season, applying a balanced fertilizer in early spring as new growth emerges. The thick, glaucous foliage offers moderate resistance to slugs, though monitoring may be necessary in damp conditions; deer may browse the leaves in areas where they are prevalent.
