Harvest Tips
Red Sage is ornamental and not typically harvested. However, you can cut flower stems for arrangements when blooms are fully open but not yet fading. Deadhead regularly by pinching or cutting spent flower spikes to the next leaf node to extend the blooming season significantly. In frost-prone zones, cut back plants in fall before frost, or dig and pot up for indoor winter growing.
Fun Facts

- 🌱 The name 'Salvia' comes from the Latin word 'salvus' meaning 'safe' or 'well,' referring to the medicinal properties associated with many sage species.
- 🌱 Hummingbirds are irresistibly attracted to Red Sage's scarlet flowers; the tubular shape perfectly matches a hummingbird's long, slender beak for accessing nectar.
