Overview
Registered in 2009 by K. Walek, *Hosta* 'Sea Blue Monster' is a giant blue-green cultivar resulting from open pollination of *Hosta* 'Brookwood Blue'. Its most distinctive features are the broadly ovate, convexly cupped leaves with a glaucous bloom on the undersides and moderate corrugation, reaching over 13 inches in length.
In the Garden
This cultivar forms an upright to mounding clump approximately 58 inches (147.3 cm) in diameter and 25 inches (63.5 cm) in height at maturity. It performs best in partial to full shade, as typical for blue-leaved hostas, where the glaucous bloom is best preserved. Its substantial size makes it suitable as a specimen plant or for the back of a shaded border, paired with ferns or other shade-tolerant perennials.
Care Notes
Provide consistent moisture, especially during establishment, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, it is susceptible to slug damage and deer browsing, so protective measures may be necessary in areas where these pests are prevalent.
