Hosta 'Blue Dolphin'
 

Registered in 2019 by Rick Sawyer of Maine, this cultivar is an upright growing, large size (23 inches high by 40 inches wide) seedling of H. 'Sea Mermaid'. It is a light greenish blue (119B RHS Colour Chart) with leaves that are slightly cupped, deeply corrugated and have cuspidate leaf tips with a cordate base that often overlaps itself. Near white flowers bloom from mid-June into July on scapes 38 to 44 inches tall followed by seeds whose viability was not known at the time of registration.

The registration materials state: "...Large, upright presentation of nearly round, rumpled, corrugated leaves. Large white flowers bob & sway on extra-long scapes...If grown in shade, the original bluish color holds longer, but eventually turns a moderate olive-green (137B)."
