Brother Stefan Hosta has large, very thick and heavily corrugated leaves that are slightly cupped and round. This thick, puckered texture is its signature trait. It features an irregular, vibrant chartreuse to luminous golden-yellow center framed by a wide, contrasting dark green to blue-green margin. The center color intensifies to gold as the season progresses. Near-white, bell-shaped flowers bloom on strong, sturdy scapes in early summer.
