Hosta 'Groo Bloo'
 

An open-pollinated seedling of H. 'Elegans', this cultivar was originally credited to Paul Aden of New York. Recently, its status has been changed to "unidentified originator " and it was registered by Mark Zilis of Illinois in 2010. The foliage is medium blue-green which changes to dark green by mid-summer. A large size plant, it grows to 26 inches in height and a massive 92 inches wide at maturity. The leaves are heavily corrugated, slightly wavy, moderately twisted and have thick substance. Its tubular, near white flowers bloom in late June and set viable seeds.

According to The Hostapedia by Mark Zilis (2009), "...disappeared from nursery lists sometime during the 1980s...it was rumored to be the same as 'Big Mama'...a few nurseries have begun offering it again..."
