H. ‘Buckanon’

Overview

Hosta 'Buckanon' is a giant blue-green cultivar registered in 1983 by S. Moldovan, derived as a hybrid of Hosta sieboldiana. It is distinguished by its substantial leaf dimensions—14.5 inches (36.8 cm) long and 12 inches (30.5 cm) wide—and its distinctive whitish blue leaf margins, which contrast with the deeper blue-green blade interior. The plant forms a large, dense mound reaching 48 inches (121.9 cm) in diameter and 32 inches (81.3 cm) in height.

In the Garden

Hosta 'Buckanon' is best sited in partial to full shade, where its blue-green foliage retains its color most effectively. The broad, heavily textured leaves with 16 vein pairs create a bold, architectural presence in the shade garden, and the whitish blue margins provide subtle definition without high contrast. This cultivar pairs well with ferns, Heuchera, and other shade-tolerant perennials that complement its massive scale. Given its mature spread of 4 feet, it is suitable as a specimen plant or as a background element in larger borders, though it may be too large for standard container cultivation. The scape height is variable, reported as 36 inches (91.4 cm) but also noted as 0 inches, suggesting potential inconsistency in flower stalk development.

Care Notes

Hosta 'Buckanon' performs best in consistently moist, well-drained soil rich in organic matter. It is moderately susceptible to slug and snail damage, which can disfigure the large leaves, and deer may browse the foliage. Regular watering during dry periods supports optimal leaf size, while a balanced, slow-release fertilizer applied in early spring encourages vigorous growth. Hardiness zones are not formally documented, but as a H. sieboldiana hybrid, it is presumed to be cold-hardy in temperate climates typical of hosta cultivation.
