Growth Stages

1

Seedling

2-3 weeks

Tiny emerged seedlings with first true leaves appearing within 7-10 days; very delicate

Keep soil consistently moist but not waterlogged; provide bright light; maintain 70-75°F; thin overcrowded seedlings

2

Vegetative Growth

4-6 weeks

Young plant developing multiple stems and aromatic, gray-green foliage; no flowers yet

Pinch growing tips to encourage bushiness; maintain moderate moisture; begin light fertilizing every 2-3 weeks

3

Pre-flowering

2-3 weeks

Plant reaches 12-18 inches tall with full foliage structure; flower buds beginning to form at branch tips

Continue pinching if desired for fuller shape; increase fertilizer frequency; ensure consistent water during this transition

4

Flowering & Blooming

4-6 months (summer through fall/winter)

Tubular mauve-purple flowers open sequentially along spikes; plant 2-4 feet tall; continuous blooming

Deadhead spent flowers to encourage more blooms; fertilize every 2-3 weeks with balanced or flower-promoting formula; maintain steady water supply

5

Winter Dormancy/Rest

3-4 months

Flowering slows or stops in cold areas; plant may drop foliage in zones below 9; minimal growth

Reduce watering significantly; hold off on fertilizer; protect from hard freezes with frost cloth if temps drop below 25°F; prune in spring

Fun Facts

  • 🌱 Mauve Queen is a relatively recent introduction to horticulture, developed as an improved cultivar of wild Salvia madrensis from Mexico, selected specifically for its larger mauve flowers and prolonged bloom period.
  • 🌱 The plant's name 'Mauve Queen' refers to the distinctive mauve (grayish-purple) color of its flowers, which is named after the synthetic mauve dye first synthesized in 1856.
  • 🌱 Hummingbirds can visit Mauve Queen blooms up to 10-15 times per hour during peak nectar flow, and a single plant can be the primary nectar source for a territory of several birds during the growing season.
