H. ‘Harry A. Jacobsen’

Overview

Registered in 1988 by R. Pierson, this large hosta cultivar is distinguished by its blue-green leaves with gold margins and chartreuse edge coloration. The leaves exhibit small undulations along the margins, with 12 pairs of veins, and the plant forms a substantial mound reaching 36 inches (91.4 cm) in diameter and 17 inches (43.2 cm) in height.

In the Garden

'Harry A. Jacobsen' performs best in partial to full shade, typical for blue-green hostas, where its leaf coloration remains most stable. At mature size, it forms a broad, dense clump suitable for mid-border placement or as a specimen in woodland gardens. Its large leaves pair well with ferns, astilbes, and other shade-tolerant perennials that contrast in texture or color.

Care Notes

Water regularly during dry periods, particularly in the first growing season, and apply a balanced fertilizer in early spring as new growth emerges. Standard slug and deer precautions are advisable, as the broad leaves are attractive to both pests.
