This tissue culture sport of H. 'Blue Mammoth' was registered by Mark Zilis of Illinois in 2003. It is a giant size hosta which grows over 28 inches tall with a spread of about 65 inches wide with oblong to ovate leaves that are moderately corrugated and have thick substance. The near white flowers start to bloom in late June followed by viable seeds.
 

According to The Hostapedia by Mark Zilis (2009), "...listings of this cultivar keep showing up as' wooly Mammoth' (versus the correct' woolly Mammoth')."

Zilis (2009) continues, "Slow to increase but eventually becomes huge if given enough moisture. The slightly arching leaves accentuate the higher midribs. The leaves fold and pleat toward the tip in well-grown plants."
