History
Cinnamon Basil (Ocimum basilicum) is a treasured heirloom herb believed to have originated from traditional basil varieties cultivated in Mexico and Central America, where the warm, spiced fragrance of its leaves made it a prized culinary and aromatic plant long before it reached European and North American gardens. Distinguished by its striking purple stems, lavender-pink flower spikes, and warm cinnamon-clove fragrance, this basil variety has long been valued as much for its ornamental beauty as its culinary versatility. Today it is a favorite among herb gardeners who want something beyond the ordinary — a basil that perfumes the garden, attracts pollinators, and brings a unique spiced sweetness to teas, desserts, and savory dishes alike. Open-pollinated and non-GMO.

Flavor Profile
Cinnamon Basil offers a sweet basil foundation layered with warm cinnamon and clove-like spice notes — a flavor profile that is immediately recognizable and unlike any other basil variety. The fragrance is warm, exotic, and slightly floral. Fresh leaves add a spiced sweetness to fruit salads, teas, and desserts; dried leaves retain their fragrance beautifully and add an exotic note to potpourri and herbal blends. This is the basil that surprises people — one sniff and they're hooked.
Growth Type & Harvest Yields
Cinnamon Basil is a fast-growing, productive annual that thrives in heat and full sun. Plants develop an upright, bushy habit and produce abundant fragrant foliage throughout the season. The ornamental purple stems and lavender flower spikes make it one of the most visually striking herbs in the garden. Regular harvesting keeps plants productive and delays flowering — pinch flower buds as they appear to extend the leaf harvest. A planting of 4–6 plants provides generous harvests for fresh use, drying, and potpourri all season long.
Disease Resistance
- Generally vigorous and resilient when grown in warm, well-drained conditions
- Proper spacing and airflow help reduce powdery mildew and leaf spot
- Water at soil level — wet foliage in humid conditions invites fungal issues
- Tip: Lean soil produces more intensely fragrant leaves — don't over-fertilize
Growing Tips & Planting Dimensions
- Spacing: 10–12 inches between plants; 18–24 inches between rows
- Sow depth: 1/4 inch — cover lightly with fine seed-starting mix
- Germination: 7–14 days at soil temps of 65–70°F
- Full sun — at least 6–8 hours of direct sunlight daily
- Prefers rich, well-drained soil; keep evenly moist but never waterlogged
- Start indoors 4–6 weeks before last frost; transplant after nights stay consistently above 50°F
- Pinch growing tips regularly to encourage bushy, productive plants
- Remove flower buds if growing primarily for leaf production; let some flower for pollinators
🌱 Good Things Come in Small Packages
Cinnamon Basil seeds are small — but don't let their size fool you. These little seeds carry everything needed to grow into vigorous, fragrant plants. They just ask for a little extra care at germination. Follow these steps and you'll be well on your way.
How to Germinate Successfully:
-
Start with the right foundation. Use a fine seed-starting mix — not garden soil or coarse potting mix. Sift it if needed. Small seeds need a smooth, even surface to make good contact and germinate reliably.
-
Cover lightly — just barely. Press seeds onto the moist surface and cover with no more than 1/8 inch of finely sifted mix. These seeds don't need light to germinate but they don't want to be buried either.
-
Mist, don't drench. Use a spray bottle to keep the surface evenly moist. Watering from above can wash small seeds away before they ever get started.
-
Warmth is your friend. These seeds germinate best at 65–70°F — basically normal room temperature. A heat mat can help if your space runs cool.
-
Trap the humidity. Cover your tray with a humidity dome or a loose piece of plastic wrap. This keeps moisture and warmth stable while you wait.
-
Give them time. Keep conditions consistent, resist the urge to overwater, and trust the process — they will sprout.
-
Thin with scissors, not fingers. Once seedlings appear, snip extras at the soil line rather than pulling. These roots are close together and pulling one can disturb its neighbors.
When to Plant
Start seeds indoors 4–6 weeks before your last frost date. Transplant outdoors after frost danger has passed and soil temperatures are consistently above 60°F. Find your frost dates and hardiness zone at the USDA Plant Hardiness Zone Map.
