H. ‘Jarno’

Hosta ‘Jarno’ is a registered cultivar (2016) .

Year registered	2016
Section class	IV-3 (Small)

Overview

Registered in 2016, *Hosta* 'Jarno' is a small-sized hybrid derived from a cross between *Hosta* 'Korean Snow' (pod parent) and *Hosta* 'June' (pollen parent). Its distinguishing feature is a green leaf blade with greenish-yellow, flat margins, combined with a compact, mound-like habit.

In the Garden

'Harno' forms a dense mound reaching approximately 14 inches (35.6 cm) in height and 16 inches (40.6 cm) in diameter at maturity. It is noted for high sun tolerance and strong pest resistance, making it suitable for locations that receive more light than typical hosta positions. Its small size and tidy habit recommend it for container cultivation, rock gardens, or the front of shaded borders, where it pairs well with other small perennials such as ferns or heucheras.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. While 'Jarno' exhibits good pest resistance, standard precautions against slugs and deer remain advisable in high-pressure areas.
