Hosta ‘Sum and Substance’

Hosta ‘Sum and Substance’ after I brought it home on 6-7-18, #455-13.

Hosta ‘Sum and Substance’

2004 Hosta of the Year
1990 Alex J. Summers Award
Royal Horticultural Society’s Award of Garden Merit
 

Developed by Florence Shaw and registered on her behalf by Paul Aden in 1980. Its parentage is unknown although there is some speculation…

There are at least 55 registered sports from Hosta ’Sum and Substance’ and 38 cultivars with it as a parent.

I found this Hosta ‘Sum and Substance’ while plant shopping with my sister and her husband at Mast’s Greenhouse on June 7, 2018. This legendary Hosta cultivar has been on my Hosta wish list for a very long time and I was glad Mast’s had several to choose from.

I did some rearranging with the old shade bed and put the Hosta ‘Sum and Substance’ between the Hosta sieboldiana ‘Elegans’ and ‘Guacamole’. Hosta ‘Red October’ had been in this spot but it was having some difficulty. When I dug under ‘Red October’ I found a huge mole run and the Hosta’s roots were even barely touching the soil. So after removing Hosta ‘Red October’ and several Iris, I dug around in the soil to fill in the holes and put Hosta ‘Sum and Substance’ in that spot. ‘Red October’ is happy in its new location, too.

Someday the leaves will grow much larger, but when this photo was taken the largest was 5 1/4″ wide x 7 1/2″ long.

Hosta ’Sum and Substance’ is a very large cultivar that can grow 36” tall and around 70” wide in time if grown in optimum conditions. The large, thick leaves are moderately corrugated, slightly cupped up and down and are resistant to slug and snail damage. I have read where the leaves can grow 20” long x 15” wide. Only time will tell.

As with all Hosta, best performance is achieved with consistently moist soil. If your Hosta isn’t growing well, it is likely a problem with moisture and/or the soil.

Even though I just brought this Hosta ‘Sum and Substance’ home last June 7, it has become quite a show-stopper. Very bight and cheery for sure and starting to flower.

I will continue adding more photos and information as time goes by.
