  • Hardiness: USDA Zone 6

 

 

 

Perennial for 2004

Autumn Sage

Salvia greggii 'Pink Prefernce'

‘Pink Preference’ is a cultivar of Autumn Sage that was selected for its bright pink flowers. Like the species, it is a heat and drought tolerant perennial that starts blooming in the spring but blooms most in the autumn as other flowers in the garden start to fade. It forms a two to three foot mound and attracts hummingbirds and butterflies to the garden. Pruning to six inches high each spring will help keep Autumn Sage dense and full.

  • Exposure: Full
  • Soil: Well-drained
  • Hardiness: USDA Zone 6

Firebush thrives in the summer heat and attracts hummingbirds and butterflies to the garden.
