Persian basil grows very similar to other basils. It does well in fertile, well-draining soils, and can tolerate some drought. It has been much slower to flower than the common Genovese basil and more resistant to bolting in hot, dry weather.
Taste and Smell
Persian basil is very mild in flavor. It can be used fresh in salads as whole or chopped leaves. It has a hint of licorice and mint as well as the savory, green flavor common to most basil. The leaves are a bit meatier than Italian-style basils.
There is a hint of cinnamon in the flower blossoms. The leaves smell more strongly of licorice than some other basils. Overall, though the aroma is mild like the flavor.
Persian basil has green leaves with purple hued stems and veins. The leaf color is darker and more subdued than the shiny, brightness of the more common Genovese basil. The leaves are also more narrow and elongated in shape.
Persian basil has purple flower stakes with white flower blooms. The stakes grow from the center of the leaves starting the size of a button and growing to 3-4 inches in length.
The plants are about 1 foot wide with minimal pinching. However they can spread out a few feet if you continually pinch growing heads to encourage bushiness.
They also seem perfectly happy to grow in large , overcrowded groups, and do an excellent job at stifling weeds. The plants along the outer perimeter will lean over to get sun and air and then set new roots and spread. Even well-shaded inner leaves show no signs of discoloration. So, I suspect this plant can even tolerate a fair amount of shade or being grown in indirect window sunlight.
Mature height in fertile soil ranges between about 3-4 feet. The plants are shorter in drier, less fertile soil.
- Starts easily from seed. Can be direct planted or transplanted.
- This basil grows slower than other basils at first. So it may need weeding for the first few weeks. But then it catches up quickly and does exceptionally well growing through hot weather.
- Needs warm temperatures to germinate. Seeds started in late May in North Carolina, in 80 degrees F germinated in 2-3 days.
- Water daily until plants are at least a few inches tall for faster growth rates.
- Thinning is optional. This plant seems to self-select the winners if you over seed and then adjusts well to overcrowding.
- It’s beautiful to plant in bunches for more impact than from individual plants.
