Establishment
2-3 weeksYoung transplant with 4-6 leaves, beginning to develop branching structure
Water regularly to keep soil consistently moist but not waterlogged. Pinch back growing tips to encourage bushiness. Avoid fertilizing for first 2 weeks.
Vegetative Growth
4-6 weeksPlant develops full bushy structure with numerous stems and dark green lanceolate leaves
Continue pinching back tips for fuller plant. Apply balanced fertilizer every 2-3 weeks. Maintain consistent moisture. Mulch around base to conserve water and regulate soil temperature.
Flowering
8-12 weeks or until frostDense spikes of tubular deep purple-blue flowers appear on branch tips; flowers open progressively from bottom to top
Deadhead spent flower spikes to encourage continuous blooming. Switch to higher phosphorus fertilizer (higher middle number) every 2-3 weeks to support flower production. Maintain steady watering.
Peak Bloom
4-8 weeks or longerPlant covered with abundant flower spikes; continuous blooms from midsummer to fall; attracts numerous hummingbirds and bees
Continue deadheading regularly. Monitor for spider mites and other pests in hot weather. Reduce nitrogen fertilizer to prevent excessive leafy growth at expense of flowers. Pinch any new vegetative shoots to maintain flowering focus.
Decline/Dormancy
2-4 months (winter)In zones 9-11, growth slows in winter; in colder climates, frost kills plant or stops growth entirely
In warm zones, reduce watering and fertilizing. Can be cut back by half and brought indoors as houseplant in colder regions. Store in bright, cool location (50-60°F) with minimal watering. Resume care in spring.

Fun Facts
- 🌱 Salvia Amistad is a sterile hybrid, meaning it does not produce viable seeds, but this makes it an even better bloomer because the plant continues producing flowers all season rather than redirecting energy to seed production.
- 🌱 The name 'Amistad' means friendship in Spanish, reflecting the hybrid nature of this plant as a cross between two Salvia species working together.
- 🌱 Hummingbirds can visit a single Salvia Amistad plant hundreds of times per day during peak bloom, making it one of the most efficient plants for supporting hummingbird populations in gardens.
