Overview

Registered in 1999, 'Rosedale Golden Unicorn' is a self-pollinated selection from the seedling H. 'RD-BS-1'. This large hosta is distinguished by its broad, green leaves with wide, yellow margins that provide strong contrast throughout the growing season.

In the Garden

As a large hosta, 'Rosedale Golden Unicorn' reaches a mature spread of approximately 36-48 inches (91-122 cm) with leaves measuring 10 inches (25.4 cm) long and 9 inches (22.9 cm) wide. It performs best in partial to full shade, where the gold margins remain bright without scorching. This cultivar works well as a specimen or in mixed shade borders, pairing effectively with ferns, astilbes, and other shade-tolerant perennials. Its substantial leaf size makes it suitable for use as a groundcover in larger shaded areas.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, it is susceptible to slug and deer damage, so protective measures may be necessary in areas where these pests are prevalent.
