A Gilded Giant That Lights Up the Shade Garden
Bob Solberg introduced Hosta 'Final Summation' as a sport of the legendary Sum and Substance. It inherits the massive scale of its parent but adds a brilliant golden-yellow centre. Each nearly round leaf is moderately cupped with 12 to 13 deep vein pairs. Hardy from zones 3 to 9, it thrives in Canadian shade gardens across the country. Its bold golden colour and giant spread make it a standout landscape specimen.
-
Luminous Golden Centre: A brilliant golden-yellow centre is framed by a dark green margin about 3 cm wide. The margin is slightly rippled for added texture.
-
Corrugated Grandeur: Each leaf is moderately cupped and lightly wavy. Twelve to thirteen deep vein pairs catch the light and add depth to the garden bed.
-
Massive Landscape Presence: The mound spreads to 152 cm across at maturity. Its dense, slightly shiny canopy suppresses weeds and defines garden spaces.
-
Tall Summer Scapes: Yellow flower scapes rise over 100 cm above the foliage in July and August. They carry pale lavender tubular flowers that add a soft vertical accent.

Grower's Tip: Give this hosta a few hours of morning sun to deepen the golden colour. Its thick leaf substance handles brighter light well in northern latitudes. We verify the margin width and golden intensity at our Bécancour trial fields before any plant is cleared for shipping, ensuring every specimen is True to Type.
