Overview
A sport of *Hosta* 'Sagae', registered in 1997, 'Yellow Flash' is a large, upright cultivar distinguished by its green leaves with broad, yellow, slightly rippled margins. The leaf center is light green, while the margin measures approximately 0.5 inches (1.3 cm) wide, creating a strong contrast against the dull-surfaced blade.
In the Garden
'Yellow Flash' reaches a mature diameter of 47 inches (119.4 cm) and a height of 21 inches (53.3 cm), with scapes extending to 37.5 inches (95.3 cm). It performs best in partial to dappled shade, where the gold margins hold their color without scorching. Its upright habit and moderate growth rate make it suitable for mid-border positions or as a specimen in shaded beds; companion plants include ferns, *Heuchera*, and other shade-tolerant perennials.
Care Notes
Provide consistent moisture during the growing season, particularly in warmer climates, and apply a balanced fertilizer in early spring as new growth emerges. As with most hostas, slug and deer damage may occur and should be managed through routine monitoring or protective measures.
