Hosta 'Krossa Regal'
aka Ginba Gibōshi or Chodai Giniro Gibōshi

Introduced by Gus Krossa who imported it from Japan this "classic" cultivar 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 H. nigrescens...more likely a hybrid of H. rectifolia x H. nigrescens or H. rectifolia x 'Tokudama'..."

This is a slow growing, giant size (33 inches high by 71 inches wide) plant with a vase shaped mound of rich blue foliage. Its leaves are slightly wavy, smooth textured with good substance. Medium lavender, funnel shape flowers are borne on tall (3 to 5 feet tall) scapes from 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-size, 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.

From the Field Guide to Hostas by Mark Zilis (2014), "...is known for its "blue" foliage, its early season color is actually more of a powdery or silvery grey that differs from the blues of the Sieboldianas and Tokudamas."
