Colossal chartreuse classic! Gorgeous, award winning, and immensely popular, Hosta 'Sum and Substance' has glossy, textured leaves that make a bold statement. Light lavender flowers on 40-45" scapes in midsummer. Needs some sun for best color, develops a yellow-gold color with more light. Prefers 1/4 to 3/4 day of sun. Very heavy substance, good slug resistance, and good sun tolerance.
