Hosta Big Mama will form an open mound of about 30"-36" in height with a spread of up to 60" at maturity. Giant deep blue green heart shaped leaves, lightly corrugated and cupped, thick substance. A very large plant, so give it plenty of room. It is slow to get going but will reach a good size in 5 yrs or so. Pale lavender flowers on 48" tall scapes, in July/August. Makes a great background plant. Very resistant to slugs and snails. Partially sun tolerant but does better in shade.
