📏
Spacing: 18-36 depending on mature size (check specific variety) inches
📅
Days to maturity: Varies widely; most reach mature size in 2-3 years
🌱
Planting depth: Plant at same depth as nursery container; do not bury crown

Growth Stages

1

Establishment

4-8 weeks

Young transplants with limited root systems; foliage is compact and emerging

Water regularly (weekly) for first 4-6 weeks to encourage deep rooting. Avoid overwatering. Mulch lightly with gravel. Protect from wind if in exposed location.

2

Vegetative Growth

2-6 months

Rapid expansion of foliage; plant develops deeper root systems; compact bushy form

Reduce watering frequency as roots establish. Prune lightly to encourage bushiness. Remove any dead or damaged stems. Minimal fertilizer needed.

3

Flowering

4-12 weeks depending on species

Colorful flower spikes, clusters, or blooms appear; foliage remains aromatic and dense

Deadhead spent flowers to encourage continued blooming and tidiness. Avoid heavy pruning during flowering. Water only if extremely dry.

4

Dormancy/Winter

3-5 months

Foliage may fade or discolor in cold zones; growth slows dramatically; some evergreen varieties retain color

No watering needed in most climates (winter rain provides moisture). Ensure excellent drainage to prevent root rot. Do not prune in fall; prune in spring after last frost.

5

Rejuvenation

4-8 weeks

Spring growth returns; new shoots emerge from base; plant may benefit from renewal pruning

Prune dead winter damage. Cut back up to 1/3 of plant height in early spring to rejuvenate older plants. Resume light watering if spring is dry.

Companion Planting

Plan your garden →

Plant with:

Santolina Catmint (Nepeta) Russian Sage (Perovskia) Germander (Teucrium) Stonecrop (Sedum) Ornamental grasses (Stipa, Festuca) Thyme Oregano Blanket Flower (Gaillardia) Coreopsis

Avoid planting near:

Water-loving plants (Hostas, Astilbe, Ferns) Heavy feeders requiring rich, moist soil Plants requiring frequent watering (Hydrangea, Oakleaf Hydrangea) Moisture-dependent perennials (Japanese Primrose, Astilboides)

Common Pests

  • Spray with strong water stream; use neem oil or miticide if severe. Increase air circulation around plants.

  • Use yellow sticky traps; spray with insecticidal soap or horticultural oil; encourage beneficial insects.

  • Blast with water; use insecticidal soap; apply neem oil. Release ladybugs for biological control.

  • Prevent with perfect drainage; do not overwater. Remove and destroy infected plants. Improve soil drainage with added sand or gravel.

  • Improve air circulation; avoid overhead watering. Apply sulfur dust or neem oil if needed.

Harvest Tips

Harvest aromatic foliage (lavender, rosemary, sage) in early morning after dew dries but before heat of day. Cut stems just above leaf nodes for continuous branching. Deadhead flowers regularly to extend bloom season. For drying, harvest just as flowers open. Most Mediterranean perennials don't require heavy harvesting; light pruning maintains shape.

Fun Facts

  • 🌱 Mediterranean plants evolved their drought tolerance over millennia to survive summers with virtually no rainfall, developing deep root systems and waxy or hairy leaves that reduce water loss.
  • 🌱 Lavender has been cultivated for over 2,500 years and was used by ancient Romans in bathhouses; it remains the most commercially valuable culinary and medicinal herb globally.
  • 🌱 Many Mediterranean perennials produce essential oils as a drought adaptation—these concentrated compounds help the plant survive heat and attract pollinators, and they're what make these plants so aromatic and valuable to humans.
