H. ‘Noah's Ark’

Overview

Registered in 2009 by K. Walek of the American Hosta Society, 'Noah's Ark' is a giant blue-green hosta of unknown parentage. Its most distinctive features are its exceptionally large, heavily corrugated leaves with dark green margins and a glaucous bloom on the undersides.

In the Garden

'Noah's Ark' forms a substantial mound 60 inches (152.4 cm) in diameter and 22 inches (55.9 cm) tall, making it suitable as a specimen plant or as a bold accent in large borders and woodland gardens. It performs best in partial to full shade, as is typical for blue-leaved hostas, where its glaucous bloom is best preserved. Companion plants might include ferns, astilbes, or other shade-tolerant perennials that contrast with its massive blue-green foliage.

Care Notes

Water regularly during dry periods to maintain leaf turgor, and apply a balanced fertilizer in early spring as new growth emerges. Like many large-leaved hostas, 'Noah's Ark' is susceptible to slug damage and should be monitored in typical hosta-growing zones; deer may also browse the foliage.
