Hosta 'Krossa Regal'

Introduced by Gus Krossa who imported it from Japan and it was registered (1980) by his wife, Alma, after his death. The Hostapedia by Mark Zilis (2009), states that it was "...registered as a sterile offspring of Hosta nigrescens...more likely a hybrid of Hosta rectifolia x Hosta nigrescens or Hosta rectifolia x 'Tokudama'..."

This is a giant sized (33 inches high) plant with a vase shaped mound of rich blue foliage. Its leaves are slightly wavy, smooth textured with good substance. Medium lavender flowers are borne on tall (3 to 5 feet tall) scapes in late July into August. It does not produce seed.

According to The Hosta Handbook by Mark Zilis (2000), this cultivar "...has become a hosta "classic" for many reasons. The large-sized, vase-shaped mound of frosty blue foliage is slug resistant and makes the perfect centerpiece plant for almost any garden."

This cultivar has appeared on several of the Popularity Polls by members of The American Hosta Society. This cultivar has been awarded the Royal Horticultural Society's Award of Garden Merit in the UK.
