Agastache nepetoides

Common name: Giant Yellow Hyssop

Native plant

A larger version of the Anise Hyssop (Agastache foeniculum), this plant is also an excellent encourager of pollinators.  Although flowers are a bit less showy, they are more abundant and early pruning to encourage branching will increase their numbers even more.  A perfect choice for woodland edges in moist areas.
