Overview
Registered in 1998, 'Old Cadillac' is a large blue-green hosta cultivar of unknown parentage. Its most distinctive features are the very shiny upper leaf surface, a glaucous bloom on the underside, and slightly blue-green margins on cordate leaves.
In the Garden
'Old Cadillac' forms a mound 28 inches (71.1 cm) tall and 42 inches (106.7 cm) in diameter, with a moderate growth rate. It performs best in typical hosta-growing zones in partial to full shade, where the blue-green leaf color is most pronounced. The substantial 12-inch (30.5 cm) leaves pair well with ferns, astilbes, and other shade-tolerant perennials; its large size makes it unsuitable for container culture.
Care Notes
Provide consistent moisture during the growing season, particularly in dry periods, and apply a balanced slow-release fertilizer in early spring as new growth emerges. Like most large-leaved hostas, 'Old Cadillac' is susceptible to slug and deer damage and may require protective measures in areas where these pests are prevalent.
