Notes
Yellow giant hyssop (Agastache nepetoides) is a perennial for borders and low maintenance gardens. It is hardy to USDA zone 4, or down to -30°F (-34°C). This plant likes full sun to part shade and average to moist soil of most types. Greenish-yellow flowers draw butterflies and bees. Plants grow 48 to 72 inches tall, so place them at the back of a bed. Deer tend to browse other plants first.
Pairs well with Blue flag, Blue fescue, and Weigela.
