Basil is a popular herb grown by gardeners and cooks alike, and for a good reason. Plants are easy to grow if you provide enough heat and light. They reward you with a bounty of fragrant, delicious leaves perfect for making pesto, putting on pizza, or adding to your favorite tomato-based recipes.
Why You Should Try Different Types Of Basil
There are thought to be an estimated fifty to one hundred and fifty different species of basil, with almost all of them cultivated as a culinary herb. One of the best parts about the plants is they offer different flavors and aromas. If you haven’t tried other types, you should add one or two new varieties to your garden.
Basil Varieties To Try
1. African Blue Basil (Ocimum kilimandscharicum × basilicum ‘Dark Opal’)
Sun Requirements: Full sun
Mature Height: 36″
Mature Spread: 36″
African blue basil stands out from other types. It is a sterile hybrid cross between camphor and dark opal basil that grows about three feet tall with a spicy fragrance. Plants produce abundant pink flowers with a deep purple base. Since they are sterile and don’t produce seed, the flowers don’t need to be pinched back like other types.
The flavor profile is different from more traditional types, though, as it inherited the camphor flavor, not everyone finds it appealing.
2. Cardinal Basil (Ocimum basilicum ‘Cardinal’)
Sun Requirements: Full sun
Mature Height: 24 to 30″
