H. ‘John Q. Adams’

Overview

Registered in 2003 by P. & J. Ruh, this large cultivar of unknown parentage is distinguished by its nearly round, dull green leaves with greenish yellow, slightly rippled margins. The leaf surface is moderately corrugated, cupped, and folded, with a lightly twisted form and a cordate base, while the upright scape is yellow.

In the Garden

'John Q. Adams' reaches a mature diameter of 52 inches (132.1 cm) and a height of 30 inches (76.2 cm), with a moderate growth rate. It performs best in partial to full shade, typical of hosta-growing zones, and its substantial size makes it suitable as a specimen or in mixed borders with ferns, astilbes, or other shade-tolerant perennials. The upright habit and intense leaf coloration allow it to stand out in the landscape, with very little tip burn noted.

Care Notes

Provide consistent moisture during the growing season, applying a balanced fertilizer in early spring as new growth emerges. Standard slug and deer precautions are advisable for this large-leaved cultivar.
