Hosta Sum & Substance is one of the larger Hostas, forming a spreading mound 28"-30" in heightwith a spread of up to 60" wide, at maturity. It has thick, broadly heart-shaped, light green leaves, up to 20"  long turning chartreuse to gold depending on sun exposure. Shiny above and thinly glaucous below, the lush foliage provides color and texture to the landscape. Dense racemes of bell-shaped, fragrant, pale lavender flowers appear in summer rising on scapes of 40" long. This is supposed to be one of the most slug resistant of all Hostas, due to its waxy leaves. Plant in sun to achieve the best leaf colouration. Certainly an eyecacthing Hosta to have in your garden. American Hosta Growers Association Hosta Of The Year 2004 & RHS Award Of Garden Merit.
