Growth Stages

1

Seedling/Transplant Establishment

4-6 weeks

Young plants with tender stems and developing silvery foliage; root system establishing in soil

Keep soil evenly moist (not wet) for first 4-6 weeks. Provide afternoon shade in hot climates. Avoid fertilizing; lavender prefers poor soil.

2

Vegetative Growth

6-10 weeks

Plant develops bushy form with increasing silvery-blonde foliage; stems elongating and branching

Reduce watering frequency. Pinch back stem tips in spring to encourage bushier growth. No fertilizer needed; use only if severely stunted.

3

Flowering

6-8 weeks (summer)

Purple flower spikes emerge on terminal stems above foliage; buds open progressively from bottom to top

Deadhead spent flowers regularly to encourage continued blooming and maintain shape. Full sun exposure maximizes flowering. Water only if soil is very dry.

4

Seed Development & Decline

4-6 weeks (late summer to fall)

If not deadheaded, flowers set seed and begin to fade and brown; foliage may become less vibrant as plant energy goes to seed production

Leave some flower heads for seed if desired, or deadhead to maintain vigor. Reduce watering further.

5

Dormancy/Winter Rest

3-4 months (late fall through early spring)

Growth slows dramatically; foliage remains silvery-blonde but may appear slightly muted; plant hardens for winter

No watering needed in most climates. Avoid fertilizing. Prune only minimal dead wood. In zones 4-5, apply mulch around (not touching) base for protection.

Harvest Tips

Cut flower spikes when lower buds are open but upper buds still closed for best fragrance and longevity; harvest in early morning after dew dries. Dry by hanging in bundles in a warm, dark, well-ventilated location for 2-3 weeks. Pinch or shear foliage lightly throughout growing season to maintain shape and encourage bushiness. Prune hard (by 1/3) in early spring or after first frost to rejuvenate.

Fun Facts

  • 🌱 The name 'Platinum Blonde' refers to the unusually pale, silvery-blonde color of the foliage, which is more pronounced than standard English lavender varieties and becomes more vibrant in cooler temperatures.
  • 🌱 Lavender has been cultivated for over 2,500 years and was used by ancient Egyptians in mummification processes and by Romans for bathing rituals.
  • 🌱 The silvery foliage is an adaptation to Mediterranean climates—the fine hairs on the leaves reflect sunlight and reduce water loss, making the plant exceptionally drought-tolerant.
