Growth Stages

1

Establishment

4-8 weeks

Young transplants with small linear leaves and woody stems beginning to develop structure

Water regularly to establish root system but allow soil to dry between waterings. Provide full sun. Stake if necessary in windy locations.

2

Vegetative Growth

3-6 months

Compact mounding plant with increasing foliage density; feathery, gray-green needle-like leaves developing full fragrance

Reduce watering as plant establishes. Light pruning to maintain shape and encourage bushiness. No fertilizer needed; thrives in poor soil.

3

Flowering

8-12 weeks (spring through early summer)

Plant covered with dense royal purple flower spikes; each spike topped with distinctive purple petal-like bracts creating a butterfly or crown appearance

Deadhead spent flowers to encourage continued blooming. Water during dry spells but maintain dry conditions. Avoid overhead watering.

4

Summer Rest

6-8 weeks

Flowering slows or ceases as temperatures rise; plant remains evergreen and ornamental with foliage focus

Minimal watering needed. Can pinch back leggy growth. Provide afternoon shade in very hot climates (above 95°F regularly).

5

Fall/Winter Dormancy

3-4 months

Growth slows significantly; plant maintains structure and foliage color; may produce sparse secondary flowers in mild winters

Discontinue fertilizing. Minimal water; only when soil is very dry. Prune lightly in late winter (zone 8) before spring growth resumes. Provide frost protection in zone 7.

Harvest Tips

Harvest flowers in mid-morning after dew dries but before intense heat, when flowers are fully open and color is most vibrant. Cut stems 6-8 inches from base. Dry by hanging in small bundles in a cool, dark, well-ventilated area for 2-3 weeks. For fresh arrangements, strip lower leaves and use within 1-2 weeks. Best harvested during peak blooming period (May-June in zone 9).

Fun Facts

  • 🌱 Spanish lavender gets its common name 'butterfly lavender' from the distinctive purple bracts that crown each flower spike, which resemble colorful butterfly wings and are actually modified leaves, not true petals.
  • 🌱 The 'Royal Purple' Francisco Coloane cultivar was selected and named for its particularly intense deep purple coloration, superior to standard Spanish lavender, and is often used in premium ornamental and Mediterranean garden plantings.
  • 🌱 Unlike English lavender (Lavandula angustifolia), Spanish lavender blooms earlier in spring and for a longer period, making it one of the first lavenders to flower and a valuable early-season nectar source for hungry spring pollinators.
