H. ‘Saishu Yahato Sito’

Overview

Registered in 2009 by K. Walek (AHS), this small hosta cultivar of unknown parentage is distinguished by its ovate green leaves edged with narrow white margins. The leaf margins are slightly rippled, and the white border measures approximately 0.1 inches (0.3 cm) wide, creating a crisp variegation on a compact plant.

In the Garden

‘Saishu Yahato Sito’ forms a dense, mound-like clump reaching 13 inches (33.0 cm) in height and 35 inches (88.9 cm) in diameter. It performs best in partial to full shade, where its white margins remain most distinct. The small leaf size (5 inches long, 2.25 inches wide) and compact habit make it suitable for rock gardens, troughs, or the front of a shaded border, where it pairs well with other small hostas or shade-tolerant perennials such as ferns or heucheras.

Care Notes

Provide consistent moisture during the growing season, applying a balanced slow-release fertilizer in early spring as new growth emerges. Like most hostas, it is susceptible to slug and deer damage; monitor regularly and apply controls as needed.
