Overview
'Yellow Flash' was registered in 1997 as a sport of 'Sagae'. The leaf is light green and dull, 10.25 in by 8.25 in with 10 veins and a cordate base. It has a slightly rippled yellow margin 0.5 in wide. The registrant recorded pale lavender, striped tubular flowers and light green pods from a clump in Chesterland, Ohio.
In the Garden
The registry gives an upright clump 47 in across and 21 in high, growing at a moderate rate, with a scape of 37.5 in.
How it compares
'Sagae' is the sport parent. It was Hosta of the Year in 2000 and won the Benedict award in 2010. Its registry entry gives 20 in high and 26 in across; the booklet gives 31 in high by 70 in wide and calls it a giant. The booklet also describes its margin changing from gold to creamy yellow or white by mid-summer, and it notes good slug resistance. Against that, 'Yellow Flash' is recorded with a light green center and a margin of only 0.5 in.
'Liberty', another sport of 'Sagae', went the other way, with a golden yellow margin 2.5 in wide on a medium blue-green leaf. It was registered at 39.4 in by 39.4 in, and the booklet gives 26 in high by 63 in wide. It was Hosta of the Year for 2012.
Flowers and other notes
The record of 'Yellow Flash' does not say whether its margin changes color over the season the way the booklet describes for its parent. The booklet's slug note applies to 'Sagae', not to this sport. General care, slugs included, is in our hosta care guide.
