H. ‘Just Joshin’

Overview

Registered in 2016, 'Just Joshin' is a medium-sized hosta cultivar of unknown pollen parentage, with *Hosta* 'Who Dat' as the pod parent. This cultivar is visually distinctive for its blue-green leaves with white margins that undergo a notable color transformation as they mature, shifting from solid green to a variable pattern of yellowish-white at the leaf base and darker green toward the apex and tip.

In the Garden

'Just Joshin' forms a flat mound reaching 14 inches (35.6 cm) in height and 30 inches (76.2 cm) in diameter, with a slow growth rate that makes it suitable for long-term placement in mixed borders or shade gardens. It performs best in partial to full shade, as typical for blue-green hostas, and pairs well with ferns, heucheras, and other shade-tolerant perennials. The broad, flat leaves and medium stature allow it to function as a groundcover or mid-border accent.

Care Notes

Water regularly during dry periods, particularly in the first growing season, and apply a balanced slow-release fertilizer in early spring as new growth emerges. Like most hostas, 'Just Joshin' is susceptible to slug and deer damage; monitor for slug activity in damp conditions.
