Nettleleaf giant hyssop is a tall native perennial with upright stems and spikes of small white to pale purple flowers. It blooms from June through September and goes dormant in winter, returning each spring from its root system.

In an HOA neighborhood

Nettleleaf Giant Hyssop takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Height up to 5 feet may appear too wild for front yards
  • Dies back completely in winter leaving bare stems
  • Natural growth habit lacks formal garden structure

Wildlife value

This plant is excellent for pollinators, attracting bees, butterflies, and hummingbirds throughout its long blooming season. The flowers provide nectar while the seeds feed birds in fall.

Native range data from the USDA PLANTS Database and regional native plant society lists. Pollinator and host plant associations compiled from GBIF, iNaturalist, and published ecological literature.
