This is a Genus of about 22 species of herbaceous perennials in the mint family (Lamiaceae) and most are native to North America and many from the southwest and Mexico. There are two subdivisions with one group native to North America and another native to Asia. The Genus name is from ancient Greek meaning "very much" and "ear of grain' describing the flower spikes. Well-drained soils are essential for these plants and wet winter feet in poorly drained soil will do them in. Plant in a raised bed or container if needed in full sun. Choose a species that tolerates southeast summers best such as 'Blue Fortune', 'Blue Boa' or the Acapulco® group. 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. Use in a pollinator garden, rock garden, drought tolerant garden or naturalized areas. Insects, Diseases, and Other Plant Problems: No significant problems. Watch for Spider mites, thrips, aphids, whitefly, and slugs
