H. ‘Lady Isobel Barnett’

Overview

Registered in 1996 as a sport of *Hosta* 'Sum and Substance', 'Lady Isobel Barnett' is a giant hosta distinguished by its large, medium green leaves with narrow cream to yellow margins. The leaves reach 18 inches in length and 10 inches in width, with a cordate base, slightly shiny upper surface, and waxy underside.

In the Garden

With a mature spread of 60 inches (152.4 cm) and height of 30 inches (76.2 cm), this mound-forming cultivar commands significant space in the border or shade garden. It performs best in partial to full shade, where its variegated foliage remains stable, and pairs well with ferns, astilbes, and other shade-tolerant perennials. Its moderate growth rate and substantial size make it suitable as a specimen plant or for filling large woodland areas.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like many large-leaved hostas, it is susceptible to slug and deer damage; regular monitoring and protective measures are recommended in typical hosta-growing zones.
