Salvia karwinskii is a perennial shrub variety of salvia that grows larger and denser than most varieties of salvia. The larger size of Salvia karwinskii provides a safe space for hummingbirds to shelter in cold weather or during the hummingbird’s hibernation period called torpor. Hummingbirds go into torpor between feedings or during cold weather. When the hummingbird goes into torpor, the bird’s feet lock around a branch and the hummingbird hangs upside down until it awakes.
