Ocimum basilicum 'Cinnamon' (Cinnamon Basil)
Ocimum basilicum 'Cinnamon' (Cinnamon Basil)
Contents
Introduction & History
Cinnamon basil is a warmly spiced variety that brings a Mexican and Central American accent to the basil family. Its leaves release a genuine cinnamon-like aroma with sweet basil undertones — a flavor combination that works beautifully in desserts, fruit salads, and spiced beverages. With its attractive pink flowers and bronze-tinged stems, cinnamon basil is one of the more ornamental culinary basils.
History & Origin
Cinnamon basil originated in Mexico and Central America, where it has been cultivated for centuries by indigenous communities. The methyl cinnamate content is a natural mutation selected and maintained by Mexican farmers. In traditional Mexican herbalism, cinnamon basil (albahaca canela) is used for teas and digestive remedies. It reached wider cultivation through seed exchanges and is now available from most herb seed suppliers.
Botanical Description
Cinnamon basil grows 40–50 cm tall with a moderately bushy habit. Stems are dark green with purple-bronze tones, particularly at the nodes. Leaves are medium-sized (4–6 cm), ovate, dark green with a slight glossy sheen. The most distinctive feature besides the aroma is the flower spikes: dense, with pink to mauve flowers emerging from purple-bronze calyces. The cinnamate ester methyl cinnamate, responsible for the cinnamon aroma, gives this variety its unique profile.
Stem: Square (quadrangular) — diagnostic for Lamiaceae • Leaves: Opposite, decussate arrangement • Height: 50 cm at maturity • Spread: 30 cm • Foliage: green • Flowers: pink (summer)
Planting & Cultivation
Sow indoors 6–8 weeks before last frost at 21–25°C, or direct sow after frost into warm soil. Germination in 7–10 days. Plant in full sun, 30 cm apart, in well-drained soil with pH 6.0–7.0. Cinnamon basil is slightly more tolerant of less-than-ideal conditions than Genovese. Full sun intensifies the cinnamon aroma; partial shade produces larger but less aromatic leaves.
| Sun exposure | Full Sun |
| Soil pH | 6.0-7.0 |
| Spacing | 30 cm |
| Seed depth | 3–6 mm (surface-sow if light-dependent germinator) |
| Water needs | Moderate |
| Soil type | Well-drained, humus-rich loam; add perlite or grit for drainage |
Cultivation Details
Cinnamon basil has a somewhat slower growth rate than sweet basil but produces reliably over a longer season. It bolts later than Genovese in hot weather. The ornamental flower spikes are attractive enough that some growers allow partial blooming for display. Pinch growing tips at 15 cm for bushier growth. Water consistently but avoid soggy soil. Feed monthly with balanced liquid fertilizer.
Climate & Hardiness
Tender annual killed by frost. Optimal growth 20–30°C. Handles heat well — Mexican origin gives it better heat tolerance than European basils. Growth stalls below 10°C. In tropical and subtropical zones (9–12), cinnamon basil can persist for 2 seasons. Slightly more drought-tolerant than Genovese basil once established.
USDA zones: 10-11
Minimum temperature: 2°C
Indoor growing: Suitable for windowsill culture with 6+ hours light
Seasonal Care
Spring: Start seeds indoors or buy transplants. Harden off before planting out after frost. Summer: Harvest regularly by cutting stems above nodes. Allow some flower spikes for ornamental value. Water 2–3 times weekly. Monthly feeding. Autumn: Heavy harvest before first frost. Process into cinnamon basil sugar or syrup. Collect seed. Winter: Not cold-hardy. Indoor growing is marginal.
Propagation
Seed is reliable and the standard method. Cinnamon basil comes true from seed with consistent cinnamon aroma. Fresh seed has high germination rates (80%+). Stem cuttings root easily in water in 7–10 days. Self-sows in warm climates if allowed to flower and set seed.
| Method | Success rate | Time | Notes |
|---|---|---|---|
| Direct sowing | 85–95% | 7–21 days | Sow after last frost, 3–6 mm deep |
| Indoor start | 90–98% | 6–8 weeks early | Use seed trays, transplant after hardening off |
| Succession sowing | — | Every 3–4 weeks | Ensures continuous harvest all season |

Native origin: Mexico
Diseases & Pests
Similar disease profile to sweet basil but with slightly better overall resistance. Fusarium wilt is less common than in Genovese types. Downy mildew can occur in humid conditions. Japanese beetles and slugs are the main pests. Good air circulation prevents most fungal issues.
Culinary Uses
Bridges savory and sweet. Desserts: infuse cream for ice cream, panna cotta, or custard; add to fruit salads (especially strawberry, peach, and mango). Beverages: outstanding in teas, both hot and iced; muddle into cocktails with dark rum or bourbon. Savory: adds complexity to Mexican mole sauces, spiced rice dishes. Try it in chocolate-based recipes — cinnamon basil and dark chocolate is a superb pairing.
| Category | Pairing suggestions |
|---|---|
| Poultry | Chicken, turkey, duck |
| Fish | White fish, salmon, prawns |
| Vegetables | Tomatoes, courgettes, aubergine |
| Dairy | Soft cheeses, butter, cream sauces |
Medicinal & Aromatherapy
Essential oil is dominated by methyl cinnamate (50–70%) rather than the linalool of sweet basil. Methyl cinnamate has anti-inflammatory and mild analgesic properties. Traditional Mexican herbalism uses cinnamon basil tea for digestive comfort and menstrual cramp relief. The warm, spicy aroma is used in aromatherapy for comfort and grounding.
| Compound | Properties |
|---|---|
| myrcene | herbaceous, earthy |
| linalool | floral |
| geraniol | rose-like |
| citral | lemony |
| apigenin | mild sedative flavonoid |
Container & Companion Growing
Container Growing
Good container performance in 20+ cm pots. The pink flowers and bronze-tinted stems make it more decorative than green basil varieties. Standard potting mix with good drainage. Water when top 2 cm dries. Feed every 2 weeks. Place in sunniest available position for maximum aroma.
• Minimum pot size: 20–25 cm Ø, 5 L+
• Shallow roots; frequent watering needed
• Use free-draining potting compost with 20–30% perlite or grit
• Ensure drainage holes; stand on pot feet to prevent waterlogging
• Feed with dilute liquid fertiliser (half-strength) every 2–3 weeks in growing season
• Indoor: Place on brightest windowsill (south-facing ideal); supplement with grow lights in winter
Companion Planting
Plant alongside tomatoes, peppers, and squash for pest deterrence. The pink flowers attract pollinators. Grows well alongside other basil varieties — makes an attractive mixed basil planting. Good companion for marigolds and zinnias in ornamental-edible borders.
| ✓ Good companions | Tomatoes, Peppers, Strawberries, Carrots |
| ✗ Avoid planting with | Fennel, Rue |
Common Mistakes to Avoid
1. Expecting sweet basil flavor — cinnamon basil is distinctly different. 2. Removing all flowers — unlike sweet basil, cinnamon basil flowers are ornamental and the leaf decline is less severe. 3. Drying for long-term storage — the cinnamon volatiles fade faster than thymol. 4. Using in heavy savory dishes where the cinnamon note might clash.
Harvesting & Preservation
Harvest stems above leaf nodes as with all basils. Best used fresh. Cinnamon basil sugar: layer fresh leaves with granulated sugar in a sealed jar for 2 weeks — the sugar absorbs the aroma beautifully. Makes excellent infused honey. Freeze leaves in ice cube trays with water or simple syrup for cocktails and desserts. The dried flower heads retain more cinnamon character than the dried leaves.
• Time of day: Early morning, after dew has evaporated but before intense midday heat volatilises essential oils
• Growth stage: Just before flowering, when essential oil concentration peaks. Once flowers open, the plant redirects energy from leaf production
• Season: Summer
• Part harvested: Leaves
• Harvest rule: Never remove more than ⅓ of the plant at once; this ensures continued vigorous regrowth
• Technique: Cut stems cleanly above a leaf node with sharp scissors or secateurs. Tearing damages tissue and invites disease

Frequently Asked Questions
Does cinnamon basil actually taste like cinnamon?
It contains methyl cinnamate, a compound also found in true cinnamon bark, so the cinnamon aroma is genuine. However, it’s cinnamon layered with sweet basil undertones — a more complex, herbal version of cinnamon.
Can I use cinnamon basil in pesto?
You can, but expect a very different result. Cinnamon basil pesto has a warm, spiced character that works surprisingly well with butternut squash ravioli and roasted beet salads. For a milder approach, blend 50/50 with sweet basil.
Are the pink flowers edible?
Yes, fully edible with a concentrated cinnamon-spice flavor milder than the leaves. They make stunning garnishes for desserts and cocktails.
