H. ‘Mary Jo’

Overview

Registered in 1987 by D. Stone and P. Ruh, *Hosta* 'Mary Jo' is a small-sized cultivar distinguished by its deep blue-green leaf margins and blue-green foliage. The leaves measure 5 inches (12.7 cm) in length and 3.75 inches (9.5 cm) in width, with nine pairs of veins, forming a compact mound.

In the Garden

'Hosta' Mary Jo reaches a mature diameter of 17 inches (43.2 cm) and a height of 8 inches (20.3 cm), making it suitable for the front of shaded borders, rock gardens, or as an edging plant. It thrives in partial to full shade and pairs well with other small hostas, ferns, or shade-tolerant perennials like heucheras. Its small stature also makes it an excellent candidate for container cultivation.

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 with most hostas, though the blue-green foliage may be less palatable to some pests.
