Yellow Giant Hyssop (Agastache nepetoides)

The rather drab yellow-green flowers are very attractive to bees and other pollinators. Other beneficial insects include parasitic wasps, bee fllies, and ladybugs.

Yellow giant hyssop spreads by rhizome. It can form colonies of plants that may reach 6 feet tall. It is a prime example of our "One-star" plants:

"One-star plants are often desired for their wildlife or plant community value, but not for the front yard. They are usually tall. It takes serious creativity to find a place for them in a formal situation." More information about our rating system can be found here: Ratings
