Hosta Seiryu

Hosta ‘Seiryu’

Hosta ‘Seiryu’ is a rare and refined Japanese hosta originating as a sport of Hosta kiyomusiensis. This uncommon cultivar is valued for its elegant, streaked foliage and subtle, natural beauty, making it an excellent choice for collectors and shaded garden settings.

The foliage features green leaves accented with irregular white streaking. As with all streaked hostas, individual plants may vary in pattern and intensity, adding uniqueness to each specimen. ‘Seiryu’ reflects the graceful, botanical character often associated with Japanese-origin hostas, offering an understated alternative to bold variegated varieties.

At maturity, ‘Seiryu’ typically forms a small to medium clump reaching approximately 10 inches tall and 15 inches wide under average garden conditions. In summer, it produces pale lavender flowers held above the foliage, though this cultivar is grown primarily for its foliage rather than floral display.

A distinctive and hard-to-find hosta for gardeners seeking something truly uncommon.
