Hosta 'Sum and Substance'

Hosta 'Sum and Substance' is the all-time classic specimen hosta. It forms a giant size (36 inches high by 70 inches wide) clump and is often used as a focal point plant in the landscape. For many decades it was thought to be a plant from Paul Aden of New York who registered it in 1980. Recently, it has been determined that 'Sum and Substance' was actually originated by Florence Shaw of Massachusetts. It is a plant with unknown parentage but Field Guide to Hostas by Mark Zilis (2014) states that it is "...possibly a hybrid of 'Bengee' with H. nigrescens..."

The leaves are moderately corrugated, have deeply lobed margins, are cupped both up and down and have a long, distinct tip. It has thick substance which  makes it resistant to slug damage.  From late July into August, it produces large pale lavender flowers on four foot tall scapes.

According to The Hostapedia by Mark Zilis (2009), this cultivar "...helped shape the interest in hostas as shade garden plants. It was introduced to the nursery trade in the early 1980s by Paul Aden and Klehm Nursery. Once specimens began maturing in gardens in the late 1980s, gardeners everywhere took notice...Van Wade of Ohio planted 'Sum and Substance' in his new collection in 1986, and by 1993. It had reached a hosta world record of 48" high by 114" wide...hybrids almost always more closely resemble the other parent...The number of sports that have been generated out of 'Sum and Substance' has been staggering..."

From the Field Guide to Hostas by Mark Zilis (2014), "I often wonder where the hosta world would be if 'Sum and Substance' had never been introduced."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Origin: Unknown but thought to have H. 'Elatior' and H. hypoleuca in its parentage...Can suffer from stem blight...Selfs very easily. It is a fine parent and has produced many sports. A classic hosta."

This cultivar has appeared on several of the Popularity Polls by members of The American Hosta Society. It was the 2004 "Hosta of the Year" by the American Hosta Growers Association. This cultivar has been awarded the Royal Horticultural Society's Award of Garden Merit in the UK.
