Salvia splendens is a tender perennial from Brazil grown as a warm-season annual throughout the US. Its vivid, upright flower spikes in brilliant red, purple, and coral are irresistible to hummingbirds, bees, and butterflies. One of the longest-blooming annuals in the landscape — plants bloom from early summer until hard frost with minimal deadheading required.
In Zone 2a, the average last spring frost is around May 30 and the first fall frost is around September 1, giving you a growing season of approximately 94 days.

Growing Tips for Salvia in Zone 2a
Zone 2a has a short growing season (~94 days). Start Salvia indoors early and use season-extension techniques like row covers and cold frames.
Start indoors 8-10 weeks before last frost; seeds need 65-70°F soil and light to germinate (surface-sow, do not cover). Transplant after last frost when soil has warmed. Salvia is frost-sensitive — even a light frost kills plants. Pinch spent spikes to encourage continued bloom. Tolerates heat and humidity well once established. In zones 9b-11b can be grown as a short-lived perennial.
