Fun Facts
- 🌱 Autumn Sage is one of the few plants that blooms heavily in fall as temperatures drop, when many other flowers fade—this counter-seasonal flowering is reflected in its common name.
- 🌱 The plant's flowers change subtly in shade and intensity based on temperature; cooler fall nights often deepen the red color and promote more prolific blooming.
- 🌱 Autumn Sage 'Autumn Red' is native to the Chihuahuan Desert and requires so little water and nutrients that it actually performs worse in typical well-fertilized, heavily watered garden soils.
