Hyssop- Yellow Giant (Agastache nepetoides)
The larger, lower leaves can be as big as a hearty slice of bread. And depending on the age and overall size of the plant, its flower spike can be up to 16 inches long! The only thing small about this plant are the creamy little flowers that crowd together on the spike. The blooms open a few at a time in late summer, shifting the color to a subtle, soft yellow.
