Rosemary Seeds – Rosmarinus officinalis | Evergreen Perennial Culinary Herb | Mediterranean Classic

Rosemary (Rosmarinus officinalis, syn. Salvia rosmarinus) is one of the most iconic and indispensable culinary herbs in the world — a fragrant, drought-tolerant, evergreen perennial with needle-like leaves and a piney, resinous aroma that transforms roasted meats, grilled chicken, pasta sauces, herb breads, and cocktails. Native to the sun-drenched rocky slopes of the Mediterranean, rosemary is a naturally tough, low-maintenance shrub that thrives on neglect once established, making it as suited to the landscape as to the kitchen. Beautiful lavender-blue flowers appear in spring and attract bees and beneficial pollinators. Open-pollinated, non-GMO.

Note: Rosmarinus officinalis has been reclassified by botanists as Salvia rosmarinus — both names refer to the same beloved herb.

Why Grow Rosemary from Seed

• Essential Mediterranean herb: Indispensable in Italian, Provençal, Greek, and Spanish cooking; widely used in Caribbean jerk marinades, North African chermoula, and classic French herbs de Provence
• Ornamental evergreen shrub: Compact to upright form (12–36 inches) with silvery-green needle foliage and lavender-blue spring flowers — beautiful in borders, containers, and as a low hedge or topiary
• Deer, drought, and pest resistant: Among the toughest herbs available; thrives on minimal water and poor, lean soil once established
• Container and indoor growing: Grows excellently in pots; bring indoors in winter in Zones below 7 for year-round kitchen access. Protect from temperatures below 28–30°F
• Pollinator plant: Lavender-blue flowers are highly attractive to bees and beneficial insects in late winter and early spring, often among the first blooms available to pollinators

Planting Guide

Important note on germination: Rosemary is one of the more challenging herbs to start from seed — germination rates are naturally lower (30–70%) and slower (14–28 days) than most culinary herbs. Sow more seed than you think you need and treat germination as a success even if only a portion sprout. Starting with a quality seed-starting mix and bottom heat significantly improves results.

• Indoor start: Sow seeds 6–8 weeks before last frost. Surface sow — do not cover; rosemary requires light for germination. Press gently onto the soil surface and mist to settle. Cover with a humidity dome to retain moisture.
• Pre-soak: Soak seeds in warm water for 8–24 hours before sowing to soften the seed coat and improve germination rates.
• Germination conditions: Bottom heat (65–85°F) significantly improves germination speed and rate. Keep consistently moist — do not allow to dry out during germination.
• Transplanting: Transplant outdoors after last frost when seedlings are 3–4 inches tall. Harden off for 7–10 days before final placement.
• Spacing: 12 inches apart; rows 18 inches apart for herb beds. Allow 24–36 inches for large landscape specimens.
• Soil and drainage: Well-drained soil is essential — rosemary is highly susceptible to root rot in wet conditions. Amend heavy clay soils with grit or coarse sand before planting.
• Containers: Use a terracotta pot with drainage holes and a fast-draining cactus or herb mix. Water when the top inch of soil is dry; do not let roots sit in standing water.
