Agastache

Giant Hyssop is an herbaceous perennial in the mint family of which most are native to North America and many from the southwest. They are showy, fragrant, long-blooming perennials with spikes of flowers that bloom most of the summer. Colors range from white to blue and shades of red and purple. Giant Hyssops are essential for a pollinator-friendly garden and have excellent resistance to browsing deer and rabbits. They are also heat and drought tolerant.

Well-drained soils are essential for this plant and wet winter feet in poorly drained soil will do them in. Plant in a raised bed or container if you have heavy soil. Use in a pollinator garden, rock garden or naturalized areas.
