Overview
Registered in 1997, 'Noah's Rainbow' is a small hosta cultivar derived as a sport of *Hosta* 'Green Gold'. Its distinguishing feature is a green leaf blade bordered by narrow, creamy white margins approximately 0.13 inches (0.3 cm) wide, with the margins slightly rippled along the leaf edge.
In the Garden
This cultivar forms a compact, mound-like clump reaching 9 inches (22.9 cm) in height and 19 inches (48.3 cm) in diameter, with a moderate growth rate. It is suitable for partial to full shade in typical hosta-growing zones and works well in rock gardens, small border fronts, or as edging. Its small size also makes it appropriate for container cultivation. Companion plants may include ferns, heucheras, or small shade-tolerant perennials.
Care Notes
Provide consistent moisture, particularly during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Standard slug and deer precautions are advisable, as hostas are susceptible to both.
