A Colossal Crown Jewel of Architectural Grandeur
Hosta 'David A. Haskell' is a giant sport of H. 'Sum and Substance', introduced by Allen Haskell. Our plants are direct divisions from a verified Originator's Stock specimen. Its massive mound of medium green foliage is edged in broad yellow margins reaching 7.6 cm (3") wide. Hardy across Canadian zones 3–9, it performs reliably from coast to coast. It is a commanding specimen plant for large shade gardens where scale and drama are the goal.

Grower's Tip: Give Hosta 'David A. Haskell' ample space and rich, well-draining soil to accommodate its fast growth and massive reach. Because our stock traces directly to the originator, our True to Type verification at the Bécancour trial fields is especially important — every division ships only when vigour and variegation meet our exacting standard.
