Overview
Registered in 1999, *Hosta* 'Unforgettable' is a medium-sized sport of a *H.* 'Gold Regal' × gold *H.* 'Tokudama' seedling. Its distinctive foliage features blue-green leaves with broad, golden yellow margins that are slightly rippled, creating a strong bicolor contrast.
In the Garden
This cultivar forms an upright, moderate-growing clump reaching 22 inches (55.9 cm) in height and 24 inches (61.0 cm) in diameter. It performs best in partial to full shade, typical for blue-leaved hostas, where the leaf color remains truest. The medium size suits placement in mixed borders, shade gardens, or as a specimen in woodland settings; it pairs well with ferns, astilbes, and other shade-tolerant perennials.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Standard slug and deer precautions are advisable, as both pests may damage the foliage.
