Overview
A sport of *Hosta* 'Krossa Regal', 'Regal Promenade' was registered in 1994 and is distinguished by its large, blue-green leaves with a prominent glaucous bloom on both surfaces, borne on semi-upright petioles. The foliage is heavily textured with smooth margins and a rounded base, while the scapes rise to a height of 40–48 inches (101.6–121.9 cm), displaying blue-green coloration.
In the Garden
This cultivar reaches a mature size of 30 inches (76.2 cm) in both height and diameter, forming a substantial, upright clump. It performs best in partial to full shade, typical of hosta-growing zones, and pairs well with ferns, astilbes, and other shade-tolerant perennials. Its large stature makes it suitable as a specimen or in the middle to back of a shaded border.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as growth emerges. Slugs may damage the foliage, and deer are known to browse the leaves, so protective measures may be necessary.
