Overview
'David A. Haskell' (1999) is a sport of 'Sum and Substance', registered by A. Malloy. The mutation changed the color scheme: where the parent is chartreuse gold throughout, this plant has a medium green center with a broad yellow margin, recorded at 3 in (7.6 cm) wide.
In the Garden
The registry describes a mound-like clump with a fast growth rate, 50 in (127.0 cm) across and 25 in (63.5 cm) high. Leaves are 18 in (45.7 cm) long by 14 in (35.6 cm) wide with 15 vein pairs and a cordate base, slightly shiny on both surfaces. The scapes are registered at 68 to 70 in (172.7 to 177.8 cm).
How it compares
'Sum and Substance' (1980), the parent, is registered bigger: 60 in (152.4 cm) wide and 36 in (91.4 cm) high, with an 18 in (45.7 cm) by 15 in (38.1 cm) chartreuse gold leaf and a waxy sheen on top. It was Hosta of the Year in 2004 and won the Benedict Garden Performance Award in 2015; 'David A. Haskell' has no award in the lists we checked.
'Liberty' (2000), a sport of 'Sagae' and Hosta of the Year in 2012, sits in the same show class but builds differently: upright, as tall as it is wide at 39.4 in (100.1 cm), with a medium blue-green leaf carrying a golden yellow margin 2.5 in (6.4 cm) wide and a glaucous bloom.
'Frances Williams' (1986), a sport of 'Elegans', offers blue-green with a chartreuse-to-yellow edge on a clump registered smaller, 36 in (91.4 cm) by 18 in (45.7 cm), with 12 by 10 in leaves.
