Vegetative Growth
8-10 weeksPlant develops bushy form with lance-shaped green foliage, reaching 12-18 inches tall
Pinch back growing tips in early summer to encourage branching and fuller shape. Reduce watering frequency as plant matures. No fertilizer needed if soil quality is adequate.
Pre-flowering
3-4 weeksPlant reaches mature height and width, beginning to form flower buds in late summer
Continue light watering during dry spells. Remove any dead or damaged branches. Stop pinching back to allow flowering.
Flowering
8-12 weeks (late August through October/November)Abundant white tubular flowers in terminal spikes appear along branches; plant may reach 2-3 feet tall and wide
Deadhead spent flowers to encourage continuous blooming. Water during extended dry periods. No fertilizing needed; avoid high-nitrogen applications.
Winter Dormancy
3-4 monthsIn colder zones, foliage may die back partially or completely; in warmer zones, plant remains semi-evergreen with minimal new growth
Reduce watering significantly. In zones 8-9, provide light mulch around base. Prune back dead wood in early spring before new growth emerges.

Fun Facts

- 🌱 The name 'Gregg's sage' honors Josiah Gregg, a 19th-century botanist and explorer who documented plants of the American West.
- 🌱 Unlike many sages, Autumn Sage blooms abundantly in fall rather than spring, making it a rare source of late-season color and pollinator food when many other plants are declining.
