Rosemary is a fragrant, evergreen herb native to the Mediterranean, prized for its needle-like leaves and woody aroma. Perfect for culinary use, ornamental borders, and container gardening, it’s drought-tolerant and highly attractive to pollinators.

Quick Facts

• Botanical name: Salvia rosmarinus (formerly Rosmarinus officinalis)

• Common name: Rosemary

• Plant type: Woody perennial herb

• Days to maturity: 80–100 days from transplant; faster from cuttings

• Height: 24–36 inches (can grow larger in warm climates)

• Sun exposure: Full sun (6+ hours/day)

• Hardiness zones: USDA 7–10 (grow as annual or container plant in colder zones)

• Spacing: 18–24 inches apart

When to Plant

• Indoors: Start seeds 10–12 weeks before last frost (note: slow to germinate).

• Outdoors: Transplant seedlings or rooted cuttings after last frost when soil warms.

• Germination time: 14–28 days at 70–75°F (21–24°C)

• Best method: Rosemary is more reliably grown from cuttings than seed.

How to Plant

1. Soil preparation: Well-drained, sandy or loamy soil. Avoid waterlogged or heavy soils.

2. Sowing depth: Surface sow or barely cover seeds with a light dusting of soil.

3. Watering: Water deeply but infrequently. Allow topsoil to dry out between waterings.

4. Fertilizing: Minimal; rosemary thrives in lean soils. Use light compost or slow-release fertilizer once per season.

Growing Tips

• In colder zones, grow in containers and overwinter indoors.

• Prune regularly to encourage bushiness and prevent woodiness.

• Avoid overwatering—root rot is a common issue in heavy soils.

• Highly deer-resistant and pest-tolerant.

Harvesting & Use

• Fresh use: Snip young sprigs as needed, preferably in the morning.

• Drying: Harvest longer stems, tie in bundles, and hang in a warm, dry place.

• Culinary use: Excellent with roasted meats, potatoes, breads, infused oils, and marinades.

• Other uses: Used in sachets, natural air fresheners, and herbal hair rinses.

Companion Plants

Pairs well with sage, thyme, lavender, and oregano in Mediterranean herb beds. Avoid planting with overly thirsty vegetables like cucumbers.
