Cinnamon basil contains high levels of cinnamate (specifically methyl cinnamate), the organic compound responsible for giving cinnamon its characteristic warm, spicy aroma and taste.

If you are growing cinnamon basil primarily for culinary use, it is best to pinch off flower buds as soon as they appear. Allowing the plant to bloom signals it to stop foliage production, which can cause the leaves to become bitter. However, the purple flower spikes are edible and attract pollinators if you choose to let a few bloom!

Freshly harvested cinnamon basil stems are best kept at room temperature with their bottom cut ends placed in a glass of water, much like a bouquet of flowers. Storing basil in the refrigerator can cause the leaves to brown and blacken due to cold damage. For long-term storage, freeze whole leaves in oil or preserve them in herbal teas and syrups.

Yes! Cinnamon basil grows exceptionally well indoors in pots on a bright, south-facing windowsill or under dedicated LED grow lights. As long as soil temperatures stay warm and the plant receives 6–8 hours of bright light daily, you can enjoy fresh basil harvests all year long.
