Perennial Basil – Two Great Varieties & How to Propagate Them
Basil is known to be an annual herb, but some varieties like African Blue and Thai are termed perennial basil because they keep producing new leaves year after year. Both species are raised in tropical areas where the climate is warm and humid. Warm, tropical zones can enjoy fresh perennial basil like African Blue and Thai all year round while areas with colder climates present some challenges when it comes to raising perennial basil, but it is not impossible if you keep it sheltered throughout the winter.
